Rear Seats  
{ CAUTION:  
Rear Seat Operation  
Sitting in a reclined position when the vehicle is in  
motion can be dangerous. Even if when buckled  
up, the safety belts cannot do their job when  
reclined like this.  
Removing the Rear Seat  
Disconnect the quick release latch plates for the  
lap-shoulder belts on the bench seat to be removed.  
The shoulder belt cannot do its job because it will  
not be against your body. Instead, it will be in front  
of you. In a crash, you could go into it, receiving  
neck or other injuries.  
1. To do this, press the tip  
of a key into the release  
hole of the safety belt  
buckle while pulling up  
on the safety belt.  
The lap belt cannot do its job either. In a crash,  
the belt could go up over your abdomen. The belt  
forces would be there, not at your pelvic bones.  
This could cause serious internal injuries.  
For proper protection when the vehicle is in  
motion, have the seatback upright. Then sit well  
back in the seat and wear the safety belt properly.  
Do not have a seatback reclined if the vehicle is  
moving.  
2. Locate the pins.  
On a three passenger seat there are two pins  
located on the inboard sides of the rear seats.

4. Repeat this procedure for the other pins.  
{ CAUTION:  
5. Pull the seat rearward about 2 inches (5 cm) and  
then lift the seat from the floor rails.  
6. Remove the seat from the vehicle.  
A seat that is not locked into place properly can  
move around in a collision or sudden stop. People  
in the vehicle could be injured. Be sure to lock the  
seat into place properly when installing it.  
7. For the first row rear  
seat, stow the safety  
belt latch by attaching  
the clip on the safety  
belt latch to the trim just  
inside the side door.  
{ CAUTION:  
A safety belt that is improperly routed, not properly  
attached, or twisted will not provide the protection  
needed in a crash. The person wearing the belt  
could be seriously injured. After raising the rear  
seatback, always check to be sure that the safety  
belts are properly routed and attached, and are  
not twisted.  
For the remaining rear seats, stow the safety belt  
latch plate on the clip at the window trim.  
1. Position the seat into the open slots in both rails.  
Push the seat forward in the rail, hooking both  
seat bases onto the pins inside of the rails.

Safety Belts  
{ CAUTION:  
Safety Belts: They Are for Everyone  
It is extremely dangerous to ride in a cargo area,  
inside or outside of a vehicle. In a collision, people  
riding in these areas are more likely to be seriously  
injured or killed. Do not allow people to ride in any  
area of your vehicle that is not equipped with seats  
and safety belts. Be sure everyone in your vehicle is  
in a seat and using a safety belt properly.  
This section of the manual describes how to use  
safety belts properly. It also describes some things not  
to do with safety belts.  
{ CAUTION:  
Do not let anyone ride where a safety belt cannot  
be worn properly. In a crash, if you or your  
passenger(s) are not wearing safety belts, the  
injuries can be much worse. You can hit things  
inside the vehicle harder or be ejected from the  
vehicle. You and your passenger(s) can be  
seriously injured or killed. In the same crash, you  
might not be, if you are buckled up. Always fasten  
your safety belt, and check that your passenger(s)  
are restrained properly too.  
This vehicle has indicators as a reminder to buckle the  
safety belts. See Safety Belt Reminders on page 3-26  
for additional information.  
In most states and in all Canadian provinces, the law  
requires wearing safety belts. Here is why:  
You never know if you will be in a crash. If you do have  
a crash, you do not know if it will be a serious one.  
A few crashes are mild, and some crashes can be so  
serious that even buckled up, a person would not survive.  
But most crashes are in between. In many of them,  
people who buckle up can survive and sometimes walk  
away. Without safety belts, they could have been badly  
hurt or killed.  
After more than 40 years of safety belts in vehicles,  
the facts are clear. In most crashes buckling up does  
matter... a lot!

Why Safety Belts Work  
When you ride in or on anything, you go as fast as  
it goes.  
Put someone on it.  
Take the simplest vehicle. Suppose it is just a seat on  
wheels.

Get it up to speed. Then stop the vehicle. The rider  
does not stop.  
The person keeps going until stopped by something.  
In a real vehicle, it could be the windshield...

or the instrument panel...  
or the safety belts!  
With safety belts, you slow down as the vehicle does.  
You get more time to stop. You stop over more distance,  
and your strongest bones take the forces. That is why  
safety belts make such good sense.

Questions and Answers About  
Safety Belts  
Q: If I am a good driver, and I never drive far from  
home, why should I wear safety belts?  
A: You may be an excellent driver, but if you are in a  
crash — even one that is not your fault — you and  
your passenger(s) can be hurt. Being a good driver  
does not protect you from things beyond your  
control, such as bad drivers.  
Q: Will I be trapped in the vehicle after a crash if I  
am wearing a safety belt?  
A: You could be — whether you are wearing a safety  
belt or not. But your chance of being conscious  
during and after an accident, so you can unbuckle  
and get out, is much greater if you are belted.  
And you can unbuckle a safety belt, even if you  
are upside down.  
Most accidents occur within 25 miles (40 km) of  
home. And the greatest number of serious injuries  
and deaths occur at speeds of less than 40 mph  
(65 km/h).  
Safety belts are for everyone.  
Q: If my vehicle has airbags, why should I have to  
wear safety belts?  
A: Airbags are supplemental systems only; so they  
work with safety belts — not instead of them.  
Whether or not an airbag is provided, all occupants  
still have to buckle up to get the most protection.  
That is true not only in frontal collisions, but  
especially in side and other collisions.

How to Wear Safety Belts Properly  
This section is only for people of adult size.  
Be aware that there are special things to know about  
safety belts and children. And there are different rules for  
smaller children and infants. If a child will be riding in the  
vehicle, see Older Children on page 1-29 or Infants and  
Young Children on page 1-32. Follow those rules for  
everyone’s protection.  
It is very important for all occupants to buckle up.  
Statistics show that unbelted people are hurt more often  
in crashes than those who are wearing safety belts.  
Occupants who are not buckled up can be thrown out of  
the vehicle in a crash. And they can strike others in  
the vehicle who are wearing safety belts.  
First, before you or your passenger(s) wear a safety  
belt, there is important information you should know.  
Sit up straight and always keep your feet on the  
floor in front of you. The lap part of the belt should be  
worn low and snug on the hips, just touching the thighs.  
In a crash, this applies force to the strong pelvic bones  
and you would be less likely to slide under the lap belt.  
If you slid under it, the belt would apply force on your  
abdomen. This could cause serious or even fatal injuries.  
The shoulder belt should go over the shoulder and across  
the chest. These parts of the body are best able to take  
belt restraining forces.  
The shoulder belt locks if there is a sudden stop or  
crash.

Q: What is wrong with this?  
{ CAUTION:  
You can be seriously hurt if your shoulder belt is  
too loose. In a crash, you would move forward too  
much, which could increase injury. The shoulder  
belt should fit snugly against your body.  
A: The shoulder belt is too loose. It will not give as  
much protection this way.

Q: What is wrong with this?  
{ CAUTION:  
You can be seriously injured if you wear the  
shoulder belt under your arm. In a crash, your  
body would move too far forward, which would  
increase the chance of head and neck injury. Also,  
the belt would apply too much force to the ribs,  
which are not as strong as shoulder bones. You  
could also severely injure internal organs like your  
liver or spleen. The shoulder belt should go over  
the shoulder and across the chest.  
A: The shoulder belt is worn under the arm. It should  
be worn over the shoulder at all times.

Lap-Shoulder Belt  
All seating positions in the vehicle have a lap-shoulder  
belt. If you are using a rear seating position with a  
detachable safety belt and the safety belt is not attached,  
see Rear Seat Operation on page 1-5 for instruction on  
reconnecting the safety belt to the mini-buckle.  
The following instructions explain how to wear a  
lap-shoulder belt properly.  
1. Adjust the seat, if the seat is adjustable, so you can  
sit up straight. To see how, see “Seats” in the Index.  
2. Pick up the latch plate and pull the belt across you.  
Do not let it get twisted.  
The lap-shoulder belt may lock if you pull the belt  
across you very quickly. If this happens, let the belt  
go back slightly to unlock it. Then pull the belt  
across you more slowly.  
3. Push the latch plate into the buckle until it clicks.  
Pull up on the latch plate to make sure it is secure.  
If the belt is not long enough, see Safety Belt  
Extender on page 1-28.  
If the shoulder portion of a passenger belt is pulled  
out all the way, the child restraint locking feature  
may be engaged. If this happens, let the belt  
go back all the way and start again.  
Position the release button on the buckle so that  
the safety belt could be quickly unbuckled if  
necessary.  
4. If equipped with a shoulder belt height  
adjuster, move it to the height that is right for you.  
See “Shoulder Belt Height Adjustment” later in this  
section for instructions on use and important safety  
information.  
1-23

5. To make the lap part tight, pull up on the  
shoulder belt.  
To unlatch the belt, push the button on the buckle.  
The belt should return to its stowed position. Slide the  
latch plate up the safety belt webbing when the safety belt  
is not in use. The latch plate should rest on the stitching  
on the safety belt, near the guide loop on the side wall.  
It may be necessary to pull stitching on the safety  
belt through the latch plate to fully tighten the  
lap belt on smaller occupants.  
Before a door is closed, be sure the safety belt is out  
of the way. If a door is slammed against a safety belt,  
damage can occur to both the safety belt and the vehicle.

Shoulder Belt Height Adjuster  
Safety Belt Pretensioners  
The vehicle has a shoulder belt height adjuster for the  
driver and right front passenger positions.  
If the GVWR (Gross Vehicle Weight Rating) of the  
vehicle is below 8,500 lb (3 855 kg) then the vehicle has  
safety belt pretensioners for the front outboard  
occupants. See Loading the Vehicle on page 4-19 to  
locate the certification label which contains the GVWR.  
Adjust the height so that the shoulder portion of the belt  
is centered on the shoulder. The belt should be away  
from the face and neck, but not falling off of the  
shoulder. Improper shoulder belt height adjustment  
could reduce the effectiveness of the safety belt  
in a crash.  
Although the safety belt pretensioners cannot be  
seen, they are part of the safety belt assembly. They  
can help tighten the safety belts during the early stages  
of a moderate to severe frontal, near frontal, or rear  
crash if the threshold conditions for pretensioner  
activation are met. And, if the vehicle has side impact  
airbags, safety belt pretensioners can help tighten  
the safety belts in a side crash or a rollover event.  
To move it down, pull on  
the center adjuster control  
labeled PULL. You can  
move the height adjuster  
up just by pushing up  
Pretensioners work only once. If the pretensioners  
activate in a crash, they will need to be replaced, and  
probably other new parts for the vehicle’s safety  
After a Crash on page 1-76.  
on the shoulder belt guide.  
After the adjuster is set to the desired position, try to  
move it down without pushing in to make sure it  
has locked into position.

Rear Safety Belt Comfort Guides  
Rear shoulder belt comfort guides may provide added  
safety belt comfort for older children who have outgrown  
booster seats and for some adults. When installed on  
a shoulder belt, the comfort guide positions the shoulder  
belt away from the neck and head.  
There is one guide for each outboard passenger  
position in the rear seats. Here is how to install a  
comfort guide to the safety belt:  
2. Place the guide over the belt, and insert the two  
edges of the belt into the slots of the guide.  
1. Locate the guide in a pocket on the side of the  
seatback.  
1-26  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3. Be sure that the belt is not twisted and it lies flat.  
The elastic cord must be under the belt and the  
guide on top.  
4. Buckle, position, and release the safety belt as  
described in previously in this section. Make  
sure that the shoulder belt crosses the shoulder.  
To remove and store the comfort guide, squeeze the  
belt edges together so that the safety belt can be  
removed from the guide. Slide the guide into its storage  
pocket on the side of the seatback.  
{ CAUTION:  
A safety belt that is not properly worn may not  
provide the protection needed in a crash. The  
person wearing the belt could be seriously injured.  
The shoulder belt should go over the shoulder and  
across the chest. These parts of the body are best  
able to take belt restraining forces.

The best way to protect the fetus is to protect  
the mother. When a safety belt is worn properly,  
it is more likely that the fetus will not be hurt in a crash.  
For pregnant women, as for anyone, the key to making  
safety belts effective is wearing them properly.  
Safety Belt Use During Pregnancy  
Safety belts work for everyone, including pregnant  
women. Like all occupants, they are more likely to be  
seriously injured if they do not wear safety belts.  
Safety Belt Extender  
If the vehicle’s safety belt will fasten around you, you  
should use it.  
But if a safety belt is not long enough, your dealer/  
retailer will order you an extender. When you go in to  
order it, take the heaviest coat you will wear, so the  
extender will be long enough for you. To help avoid  
personal injury, do not let someone else use it, and use it  
only for the seat it is made to fit. The extender has been  
designed for adults. Never use it for securing child seats.  
To wear it, attach it to the regular safety belt. For more  
information, see the instruction sheet that comes with the  
extender.  
A pregnant woman should wear a lap-shoulder belt,  
and the lap portion should be worn as low as possible,  
below the rounding, throughout the pregnancy.

The manufacturer’s instructions that come with the  
booster seat state the weight and height limitations for  
that booster. Use a booster seat with a lap-shoulder belt  
until the child passes the below fit test:  
Child Restraints  
Older Children  
Sit all the way back on the seat. Do the knees bend  
at the seat edge? If yes, continue. If no, return to  
the booster seat.  
Buckle the lap-shoulder belt. Does the shoulder belt  
rest on the shoulder? If yes, continue. If no, try  
using the rear safety belt comfort guide. See “Rear  
Safety Belt Comfort Guides” under Lap-Shoulder  
Belt on page 1-23 for more information. If the  
shoulder belt still does not rest on the shoulder,  
then return to the booster seat.  
Does the lap belt fit low and snug on the hips,  
touching the thighs? If yes, continue. If no, return  
to the booster seat.  
Can proper safety belt fit be maintained for the  
length of the trip? If yes, continue. If no, return  
to the booster seat.  
Older children who have outgrown booster seats should  
wear the vehicle’s safety belts.  
If you have the choice, a child should sit in a  
position with a lap-shoulder belt and get the  
additional restraint a shoulder belt can provide.

Q: What is the proper way to wear safety belts?  
{ CAUTION:  
A: An older child should wear a lap-shoulder belt and  
get the additional restraint a shoulder belt can  
provide. The shoulder belt should not cross the face  
or neck. The lap belt should fit snugly below the hips,  
just touching the top of the thighs. This applies belt  
force to the child’s pelvic bones in a crash. It should  
never be worn over the abdomen, which could cause  
severe or even fatal internal injuries in a crash.  
Never do this.  
Never allow two children to wear the same safety  
belt. The safety belt can not properly spread the  
impact forces. In a crash, the two children can be  
crushed together and seriously injured. A safety  
belt must be used by only one person at a time.  
Also see “Rear Safety Belt Comfort Guides” under  
Lap-Shoulder Belt on page 1-23.  
According to accident statistics, children and infants  
are safer when properly restrained in a child restraint  
system or infant restraint system secured in a rear

{ CAUTION:  
Never do this.  
Never allow a child to wear the safety belt with the  
shoulder belt behind their back. A child can be  
seriously injured by not wearing the lap-shoulder  
belt properly. In a crash, the child would not be  
restrained by the shoulder belt. The child could  
move too far forward increasing the chance of  
head and neck injury. The child might also slide  
under the lap belt. The belt force would then be  
applied right on the abdomen. That could cause  
serious or fatal injuries. The shoulder belt should  
go over the shoulder and across the chest.

system is designed for them. Every time infants and  
young children ride in vehicles, they should have the  
protection provided by appropriate child restraints.  
Infants and Young Children  
Everyone in a vehicle needs protection! This includes  
infants and all other children. Neither the distance  
traveled nor the age and size of the traveler changes  
the need, for everyone, to use safety restraints. In fact,  
the law in every state in the United States and in every  
Canadian province says children up to some age must  
be restrained while in a vehicle.  
Children who are not restrained properly can strike other  
people, or can be thrown out of the vehicle.  
{ CAUTION:  
Never do this.  
{ CAUTION:  
Never hold an infant or a child while riding in a  
vehicle. Due to crash forces, an infant or a child  
will become so heavy it is not possible to hold it  
during a crash. For example, in a crash at only  
25 mph (40 km/h), a 12 lb (5.5 kg) infant will  
suddenly become a 240 lb (110 kg) force on a  
person’s arms. An infant should be secured in an  
appropriate restraint.  
Children can be seriously injured or strangled if a  
shoulder belt is wrapped around their neck and  
the safety belt continues to tighten. Never leave  
children unattended in a vehicle and never allow  
children to play with the safety belts.  
Airbags plus lap-shoulder belts offer protection for adults  
and older children, but not for young children and infants.

If you must secure a forward-facing child restraint  
in the right front seat, always move the front  
passenger seat as far back as it will go.  
{ CAUTION:

Q: What are the different types of add-on child  
restraints?  
{ CAUTION:  
A: Add-on child restraints, which are purchased by the  
vehicle’s owner, are available in four basic types.  
Selection of a particular restraint should take into  
consideration not only the child’s weight, height,  
and age but also whether or not the restraint will  
be compatible with the motor vehicle in which it  
will be used.  
To reduce the risk of neck and head injury during  
a crash, infants need complete support. This is  
because an infant’s neck is not fully developed  
and its head weighs so much compared with  
the rest of its body. In a crash, an infant in a  
rear-facing child restraint settles into the restraint,  
so the crash forces can be distributed across the  
strongest part of an infant’s body, the back and  
shoulders. Infants should always be secured in  
rear-facing child restraints.  
For most basic types of child restraints, there are  
many different models available. When purchasing a  
child restraint, be sure it is designed to be used in a  
motor vehicle. If it is, the restraint will have a label  
saying that it meets federal motor vehicle safety  
standards.  
The restraint manufacturer’s instructions that  
come with the restraint state the weight and height  
limitations for a particular child restraint. In addition,  
there are many kinds of restraints available for  
children with special needs.

Child Restraint Systems  
{ CAUTION:  
A rear-facing infant  
seat (A) provides restraint  
with the seating surface  
against the back of  
the infant.  
A young child’s hip bones are still so small that  
the vehicle’s regular safety belt may not remain  
low on the hip bones, as it should. Instead, it may  
settle up around the child’s abdomen. In a crash,  
the belt would apply force on a body area that is  
unprotected by any bony structure. This alone  
could cause serious or fatal injuries. To reduce  
the risk of serious or fatal injuries during a crash,  
young children should always be secured in  
appropriate child restraints.  
The harness system holds the infant in place and, in a  
crash, acts to keep the infant positioned in the restraint.  
A forward-facing child  
seat (B) provides restraint  
for the child’s body  
with the harness.

Securing an Add-On Child Restraint in  
the Vehicle  
{ CAUTION:  
A child can be seriously injured or killed in a crash  
if the child restraint is not properly secured in the  
vehicle. Secure the child restraint properly in the  
vehicle using the vehicle’s safety belt or LATCH  
system, following the instructions that came with  
that child restraint and the instructions in this  
manual.  
A booster seat (C-D) is a child restraint designed to  
improve the fit of the vehicle’s safety belt system.  
A booster seat can also help a child to see out the  
window.  
To help reduce the chance of injury, the child restraint  
must be secured in the vehicle. Child restraint systems  
must be secured in vehicle seats by lap belts or the  
lap belt portion of a lap-shoulder belt, or by the LATCH  
(LATCH) on page 1-39 for more information. A child can  
be endangered in a crash if the child restraint is not  
properly secured in the vehicle.

When securing an add-on child restraint, refer to the  
instructions that come with the restraint which may be  
on the restraint itself or in a booklet, or both, and to this  
manual. The child restraint instructions are important,  
so if they are not available, obtain a replacement  
copy from the manufacturer.  
Where to Put the Restraint  
According to accident statistics, children and infants are  
safer when properly restrained in a child restraint system  
or infant restraint system secured in a rear seating  
position.  
Keep in mind that an unsecured child restraint can  
move around in a collision or sudden stop and injure  
people in the vehicle. Be sure to properly secure  
any child restraint in the vehicle — even when no  
child is in it.  
We recommend that children and child restraints  
be secured in a rear seat, including: an infant or a child  
riding in a rear-facing child restraint; a child riding in  
a forward-facing child seat; an older child riding in  
a booster seat; and children, who are large enough,  
using safety belts.  
Securing the Child Within the Child  
Restraint  
If a child restraint is secured in the right front passenger  
seat, there may be a switch on the instrument panel  
to manually turn off the right front passenger airbag.  
See Airbag Off Switch on page 1-65 and Securing  
(With Airbag On-Off Switch) on page 1-52 for more  
information, including important safety information.  
{ CAUTION:  
A child can be seriously injured or killed in a crash  
if the child is not properly secured in the child  
restraint. Secure the child properly following the  
instructions that came with that child restraint.

A label on the sun visor says, “Never put a rear-facing  
child seat in the front.” This is because the risk to  
the rear-facing child is so great, if the airbag deploys.  
CAUTION: (Continued)  
Secure rear-facing child restraints in a rear  
seat, even if the airbag is off. If you secure a  
forward-facing child restraint in the right front seat,  
always move the front passenger seat as far back  
as it will go. It is better to secure the child restraint in  
a rear seat.  
{ CAUTION:  
A child in a rear-facing child restraint can be  
seriously injured or killed if the right front  
passenger airbag inflates. This is because the  
back of the rear-facing child restraint would be  
very close to the inflating airbag. A child in a  
forward-facing child restraint can be seriously  
injured or killed if the right front passenger airbag  
inflates and the passenger seat is in a forward  
position.  
When securing a child restraint in a rear seating  
position, study the instructions that came with the child  
restraint to make sure it is compatible with this vehicle.  
If the vehicle does not have a rear seat that will  
accommodate a rear-facing child restraint, a rear-facing  
child restraint should not be installed in the vehicle,  
even if the airbag is off.  
Even if the passenger sensing system or airbag  
switch has turned off the right front passenger  
frontal airbag, no system is fail-safe. No one can  
guarantee that an airbag will not deploy under  
some unusual circumstance, even though it is  
turned off.  
Wherever a child restraint is installed, be sure to secure  
the child restraint properly.  
Keep in mind that an unsecured child restraint can move  
around in a collision or sudden stop and injure people in  
the vehicle. Be sure to properly secure any child restraint  
in the vehicle — even when no child is in it.

Lower Anchors  
Lower Anchors and Tethers for  
Children (LATCH)  
The LATCH system holds a child restraint during driving  
or in a crash. This system is designed to make installation  
of a child restraint easier. The LATCH system uses  
anchors in the vehicle and attachments on the child  
restraint that are made for use with the LATCH system.  
Make sure that a LATCH-compatible child restraint is  
properly installed using the anchors, or use the vehicle’s  
safety belts to secure the restraint, following the  
instructions that came with that restraint, and also the  
instructions in this manual. When installing a child  
restraint with a top tether, you must also use either the  
lower anchors or the safety belts to properly secure the  
child restraint. A child restraint must never be installed  
using only the top tether strap and anchor.  
Lower anchors (A) are metal bars built into the vehicle.  
There are two lower anchors for each LATCH seating  
position that will accommodate a child restraint with  
lower attachments (B).  
In order to use the LATCH system in your vehicle,  
you need a child restraint that has LATCH attachments.  
The child restraint manufacturer will provide you with  
instructions on how to use the child restraint and its  
attachments. The following explains how to attach a  
child restraint with these attachments in your vehicle.  
Not all vehicle seating positions or child restraints have  
lower anchors and attachments or top tether anchors  
and attachments.  
1-39  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Some child restraints that have a top tether are  
designed for use with or without the top tether being  
attached. Others require the top tether always to be  
attached. In Canada, the law requires that forward-facing  
child restraints have a top tether, and that the tether be  
attached. Be sure to read and follow the instructions for  
your child restraint.  
Top Tether Anchor  
If the child restraint does not have a top tether, one  
can be obtained, in kit form, for many child restraints.  
Ask the child restraint manufacturer whether or not a kit  
is available.  
Lower Anchor and Top Tether Anchor  
Locations  
i (Top Tether Anchor):  
Seating positions with top  
tether anchors.  
A top tether (A, C) anchors the top of the child restraint  
to the vehicle. A top tether anchor is built into the  
vehicle. The top tether attachment (B) on the child  
restraint connects to the top tether anchor in the vehicle  
in order to reduce the forward movement and rotation  
of the child restraint during driving or in a crash.  
j (Lower Anchor): Seating  
positions with two lower  
anchors.  
Your child restraint may have a single tether (A) or a  
dual tether (C). Either will have a single attachment (B)

additional information.  
Securing a Child Restraint Designed for  
the LATCH System  
{ CAUTION:  
If a LATCH-type child restraint is not attached to  
anchors, the child restraint will not be able to  
protect the child correctly. In a crash, the child  
could be seriously injured or killed. Install a  
LATCH-type child restraint properly using the  
anchors, or use the vehicle’s safety belts to secure  
the restraint, following the instructions that came  
with the child restraint and the instructions in this  
manual.  
Front Passenger Position  
There is a top tether anchor for the front passenger  
position with a front passenger seat. The anchor  
is located at the rear of the seat cushion on the right  
front passenger’s seat.  
Do not secure a child restraint in a position without a  
top tether anchor if a national or local law requires that  
the top tether be attached, or if the instructions that  
come with the child restraint say that the top tether  
must be attached.

Notice: Do not let the LATCH attachments rub  
against the vehicle’s safety belts. This may damage  
these parts. If necessary, move buckled safety  
belts to avoid rubbing the LATCH attachments.  
{ CAUTION:  
Do not attach more than one child restraint to  
a single anchor. Attaching more than one child  
restraint to a single anchor could cause the anchor  
or attachment to come loose or even break during a  
crash. A child or others could be injured. To reduce  
the risk of serious or fatal injuries during a crash,  
attach only one child restraint per anchor.  
Do not fold the empty rear seat with a safety belt  
buckled. This could damage the safety belt or  
the seat. Unbuckle and return the safety belt to  
its stowed position, before folding the seat.  
1. Attach and tighten the lower attachments to the  
lower anchors. If the child restraint does not have  
lower attachments or the desired seating position  
does not have lower anchors, secure the child  
restraint with the top tether and the safety belts.  
Refer to your child restraint manufacturer  
instructions and the instructions in this manual.  
{ CAUTION:  
1.1. Find the lower anchors for the desired  
seating position.  
Children can be seriously injured or strangled if a  
shoulder belt is wrapped around their neck and  
the safety belt continues to tighten. Buckle any  
unused safety belts behind the child restraint so  
children cannot reach them. Pull the shoulder belt  
all the way out of the retractor to set the lock, if  
your vehicle has one, after the child restraint has  
been installed.

2. If the child restraint manufacturer recommends that  
the top tether be attached, attach and tighten the  
top tether to the top tether anchor, if equipped.  
Refer to the child restraint instructions and  
the following steps:  
If the position you are  
using does not have a  
headrest or head restraint  
and you are using a  
dual tether, route the tether  
over the seatback.  
2.1. Find the top tether anchor.

three passenger seats only, in the rear driver  
side seating positions, use anchor point (A).  
For the rear passenger side seating positions,  
use anchor point (B). For the center seating  
positions, use anchor point (B). Never install  
two top tethers using the same top tether  
anchor.  
If the position you are  
using has an integrated  
headrest or head restraint  
and you are using a  
dual tether, route the tether  
around the headrest or  
head restraint.  
2.3. Route and tighten the top tether according  
to your child restraint instructions and the  
following instructions:  
If the position you are

Here are the most important things to know about the  
airbag system:  
{ CAUTION:  
{ CAUTION:  
Airbags inflate with great force, faster than the  
blink of an eye. Anyone who is up against, or very  
close to, any airbag when it inflates can be seriously  
injured or killed. Do not sit unnecessarily close to  
the airbag, as you would be if you were sitting on  
the edge of your seat or leaning forward. Safety  
belts help keep you in position before and during a  
crash. Always wear your safety belt, even with  
airbags. The driver should sit as far back as  
possible while still maintaining control of the  
vehicle.  
You can be severely injured or killed in a crash if  
you are not wearing your safety belt — even if you  
have airbags. Airbags are designed to work with  
safety belts, but do not replace them. Also, airbags  
are not designed to deploy in every crash. In some  
crashes safety belts are your only restraint.  
Wearing your safety belt during a crash helps  
reduce your chance of hitting things inside the  
vehicle or being ejected from it. Airbags are  
“supplemental restraints” to the safety belts.  
Everyone in your vehicle should wear a safety  
belt properly — whether or not there is an airbag  
for that person.  
Occupants should not lean on or sleep against the  
door or side windows in seating positions with  
roof-rail airbags.

Where Are the Airbags?  
{ CAUTION:  
Children who are up against, or very close to,  
any airbag when it inflates can be seriously injured  
or killed. Airbags plus lap-shoulder belts offer  
protection for adults and older children, but not for  
young children and infants. Neither the vehicle’s  
safety belt system nor its airbag system is designed  
for them. Young children and infants need the  
protection that a child restraint system can provide.  
Always secure children properly in your vehicle.  
To read how, see Older Children on page 1-29 or  
There is an airbag  
readiness light on the  
instrument panel, which  
shows the airbag symbol.  
The driver frontal airbag is in the middle of the steering  
wheel.  
The system checks the airbag electrical system for  
malfunctions. The light tells you if there is an electrical  
problem. See Airbag Readiness Light on page 3-27  
for more information.

Driver Side shown, Passenger Side similar  
If the vehicle has one, the right front passenger airbag  
is in the instrument panel on the passenger side.  
If the vehicle is a cargo or passenger van with a sliding  
door and it has a roof-rail airbag for the driver and right  
front passenger position, the roof-rail airbags are in the  
ceiling above the side window.  
1-59

For passenger vans with a sliding door, on the  
passenger side of the vehicle, you will have a separate  
roof-rail airbag for the passenger seated directly  
behind the right front passenger and the third row  
outboard passenger position.  
{ CAUTION:  
If something is between an occupant and an  
airbag, the airbag might not inflate properly or it  
might force the object into that person causing  
severe injury or even death. The path of an inflating  
airbag must be kept clear. Do not put anything  
between an occupant and an airbag, and do not  
attach or put anything on the steering wheel hub  
or on or near any other airbag covering.  
Driver Side shown, Passenger Side similar  
Never secure anything to the roof of a vehicle  
with roof-rail airbags by routing a rope or tie down  
through any door or window opening. If you do, the  
path of an inflating roof-rail airbag will be blocked.  
If the vehicle has roof-rail airbags for the driver, right  
front passenger, passengers behind the driver and right  
front passenger, and the third row outboard passengers,  
the roof-rail airbags are in the ceiling above the side  
windows. On the driver side of the vehicle, there is one  
single roof-rail airbag for either vehicles with a hinged  
door or a sliding door.

Frontal airbags may inflate at different crash speeds.  
For example:  
When Should an Airbag Inflate?  
Frontal airbags are designed to inflate in moderate to  
severe frontal or near-frontal crashes to help reduce the  
potential for severe injuries mainly to the driver’s or right  
front passenger’s head and chest. However, they are only  
designed to inflate if the impact exceeds a predetermined  
deployment threshold. Deployment thresholds are used  
to predict how severe a crash is likely to be in time for the  
airbags to inflate and help restrain the occupants.  
If the vehicle hits a stationary object, the airbags  
could inflate at a different crash speed than if the  
vehicle hits a moving object.  
If the vehicle hits an object that deforms, the  
airbags could inflate at a different crash speed than  
if the vehicle hits an object that does not deform.  
If the vehicle hits a narrow object (like a pole), the  
airbags could inflate at a different crash speed  
than if the vehicle hits a wide object (like a wall).  
Whether the frontal airbags will or should deploy is not  
based on how fast the vehicle is traveling. It depends  
largely on what you hit, the direction of the impact,  
and how quickly the vehicle slows down.  
If the vehicle goes into an object at an angle, the  
airbags could inflate at a different crash speed  
than if the vehicle goes straight into the object.  
Thresholds can also vary with specific vehicle design.  
Frontal airbags are not intended to inflate during vehicle  
rollovers, rear impacts, or in many side impacts.  
1-61  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
The vehicle may or may not have roof-rail airbags.  
See Airbag System on page 1-56. Roof-rail airbags are  
intended to inflate in moderate to severe side crashes.  
In addition, these roof-rail airbags are intended to inflate  
during a rollover. Roof-rail airbags will inflate if the crash  
severity is above the system’s designed threshold level.  
The threshold level can vary with specific vehicle design.  
Single Stage vs. Dual Stage Airbags  
Depending on the weight of the vehicle, you will have  
either “Single Stage Airbags” or “Dual Stage Airbags.”  
Vehicles that have a passenger sensing system  
also have dual stage airbags. See Passenger Airbag  
System on page 1-68.  
Roof-rail airbags are not intended to inflate in frontal  
impacts, near-frontal impacts, or rear impacts. All roof-rail  
airbags will deploy when either side of the vehicle is  
struck.  
If the GVWR (Gross Vehicle Weight Rating) of the  
vehicle is 8,500 lb (3 855 kg) or above, the vehicle may  
have single stage airbags. If the GVWR is below 8,500 lb  
(3 855 kg) then the vehicle may have dual stage airbags.  
You can find the GVWR on the certification label on the  
rear edge of the driver door. See Loading the Vehicle on  
page 4-19 for more information.  
In any particular crash, no one can say whether an  
airbag should have inflated simply because of the  
damage to a vehicle or because of what the repair costs  
were. For frontal airbags, inflation is determined by what  
the vehicle hits, the angle of the impact, and how quickly  
the vehicle slows down. For roof-rail airbags, deployment  
is determined by the location and severity of the side  
impact.  
In addition, the vehicle may have dual-stage frontal  
airbags. Dual-stage airbags adjust the restraint according  
to crash severity. The vehicle has electronic frontal  
sensors, which help the sensing system distinguish  
between a moderate frontal impact and a more severe  
frontal impact. For moderate frontal impacts, dual-stage  
airbags inflate at a level less than full deployment.  
For more severe frontal impacts, full deployment occurs.  
1-62  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Airbags supplement the protection provided by safety  
belts. Frontal airbags distribute the force of the  
impact more evenly over the occupant’s upper body,  
stopping the occupant more gradually. Roof-rail airbags  
distribute the force of the impact more evenly over  
the occupant’s upper body.  
What Makes an Airbag Inflate?  
In a deployment event, the sensing system sends  
an electrical signal triggering a release of gas from the  
inflator. Gas from the inflator fills the airbag causing the  
bag to break out of the cover and deploy. The inflator,  
the airbag, and related hardware are all part of the airbag  
module.  
Rollover capable roof-rail airbags are designed to help  
contain the head and chest of occupants in the outboard  
seating positions in the first, second, and third rows,  
if equipped. The rollover capable roof-rail airbags are  
designed to help reduce the risk of full or partial ejection  
in rollover events, although no system can prevent all  
such ejections.  
Frontal airbag modules are located inside the steering  
wheel and instrument panel. For vehicles with roof-rail  
airbags, there are airbag modules in the ceiling of the  
vehicle, near the side windows for the first, second, and  
third rows (if equipped). See Where Are the Airbags?  
on page 1-58 for more information.  
But airbags would not help in many types of collisions,  
primarily because the occupant’s motion is not toward  
those airbags. See When Should an Airbag Inflate? on  
page 1-61 for more information.  
How Does an Airbag Restrain?  
In moderate to severe frontal or near frontal collisions,  
even belted occupants can contact the steering wheel  
or the instrument panel. In moderate to severe side  
collisions, even belted occupants can contact the inside  
of the vehicle.  
Airbags should never be regarded as anything more  
than a supplement to safety belts.

What Will You See After an Airbag  
Inflates?  
{ CAUTION:  
After the frontal airbags inflate, they quickly deflate,  
so quickly that some people may not even realize  
an airbag inflated. Roof-rail airbags may still be at  
least partially inflated for some time after they deploy.  
Some components of the airbag module may be hot  
for several minutes. For location of the airbag modules,  
When an airbag inflates, there may be dust in the  
air. This dust could cause breathing problems for  
people with a history of asthma or other breathing  
trouble. To avoid this, everyone in the vehicle  
should get out as soon as it is safe to do so. If you  
have breathing problems but cannot get out of the  
vehicle after an airbag inflates, then get fresh air  
by opening a window or a door. If you experience  
breathing problems following an airbag deployment,  
you should seek medical attention.  
The parts of the airbag that come into contact with you  
may be warm, but not too hot to touch. There may be  
some smoke and dust coming from the vents in the  
deflated airbags. Airbag inflation does not prevent the  
driver from seeing out of the windshield or being able to  
steer the vehicle, nor does it prevent people from leaving  
the vehicle.  
The vehicle has a feature that may automatically unlock  
the doors (if equipped with power door locks), turn the  
interior lamps on, and turn the hazard warning flashers on  
when the airbags inflate. You can lock the doors, turn the  
interior lamps off, and turn the hazard warning flashers off  
by using the controls for those features.

In many crashes severe enough to inflate the airbag,  
windshields are broken by vehicle deformation.  
Additional windshield breakage may also occur  
from the right front passenger airbag.  
Airbag Off Switch  
If the instrument panel has one of the switches pictured  
in the following illustrations, the vehicle has an airbag  
on-off switch that you can use to manually turn on or off  
the right front passenger airbag.  
Airbags are designed to inflate only once. After an  
airbag inflates, you will need some new parts for the  
airbag system. If you do not get them, the airbag  
system will not be there to help protect you in another  
crash. A new system will include airbag modules and  
possibly other parts. The service manual for the  
vehicle covers the need to replace other parts.  
The vehicle has a crash sensing and diagnostic  
module which records information after a crash.

The passenger sensing system works with sensors that

inflating airbag. A child in a forward-facing child  
restraint can be seriously injured or killed if the  
right front passenger airbag inflates and the  
passenger seat is in a forward position.  
Accident statistics show that children are safer if  
they are restrained in the rear rather than the front seat.  
We recommend that children be secured in a rear  
seat, including: an infant or a child riding in a rear-facing  
child restraint; a child riding in a forward-facing child  
seat; an older child riding in a booster seat; and children,  
who are large enough, using safety belts.  
Even if the passenger sensing system has turned  
off the right front passenger frontal airbag, no  
system is fail-safe. No one can guarantee that  
an airbag will not deploy under some unusual  
circumstance, even though the airbag is turned off.  
A label on the sun visor says, “Never put a rear-facing  
child seat in the front.” This is because the risk to  
the rear-facing child is so great, if the airbag deploys.  
Secure rear-facing child restraints in a rear  
seat, even if the airbag is off. If you secure a  
forward-facing child restraint in the right front seat,  
always move the front passenger seat as far back  
as it will go. It is better to secure the child restraint in  
a rear seat.  
{ CAUTION:  
A child in a rear-facing child restraint can be  
seriously injured or killed if the right front passenger  
airbag inflates. This is because the back of the

The right front passenger seat is unoccupied.  
For some children, including those in child restraints,  
and for very small adults, the passenger sensing system  
may or may not turn off the right front passenger frontal  
airbag, depending upon the person’s seating posture  
and body build. Everyone in your vehicle who has  
outgrown child restraints should wear a safety belt  
properly — whether or not there is an airbag for that

If the On Indicator is Lit for a  
Child Restraint  
If the Off Indicator is Lit for an  
Adult-Size Occupant  
If a child restraint has been installed and the on  
indicator is lit:  
1. Turn the vehicle off.  
2. Remove the child restraint from the vehicle.  
3. Remove any additional items from the seat such  
as blankets, cushions, seat covers, seat heaters,  
or seat massagers.  
4. Reinstall the child restraint following the directions  
provided by the child restraint manufacturer and  
refer to Securing a Child Restraint in the Right Front  
Seat Position (With Passenger Sensing System)  
in the Index.  
5. If, after reinstalling the child restraint and restarting  
the vehicle, the on indicator is still lit, turn the vehicle  
off. Then slightly recline the vehicle seatback and  
adjust the seat cushion, if adjustable, to make sure  
that the vehicle seatback is not pushing the child  
restraint into the seat cushion.  
If a person of adult-size is sitting in the right front  
passenger seat, but the off indicator is lit, it could be  
because that person is not sitting properly in the seat.  
6. Restart the vehicle.

Additional Factors Affecting System  
Operation  
Safety belts help keep the passenger in position on the  
seat during vehicle maneuvers and braking, which helps  
the passenger sensing system maintain the passenger  
airbag status. See “Safety Belts” and “Child Restraints” in  
the Index for additional information about the importance  
of proper restraint use.  
1. Turn the vehicle off.  
2. Remove any additional material from the seat, such  
as blankets, cushions, seat covers, seat heaters, or  
seat massagers.  
3. Place the seatback in the fully upright position.  
4. Have the person sit upright in the seat, centered on  
the seat cushion, with legs comfortably extended.  
If you ever pull the shoulder portion of the belt out  
all the way, you will engage the child restraint locking  
feature. This may unintentionally cause the passenger  
sensing system to turn the airbag(s) off for some adult  
size occupants. If this happens, just let the belt go back  
all the way and start again.  
5. Restart the vehicle and have the person remain in  
this position for two to three minutes after the on  
indicator is lit.  
This allows the system to detect that person and then  
enable the right front passenger frontal airbag.

sheet metal, they may keep the airbag system from  
working properly. Changing or moving any parts  
of the front seats, safety belts, the airbag sensing  
and diagnostic module, steering wheel, instrument  
panel, roof-rail airbag modules, ceiling headliner  
or pillar garnish trim, front sensors, or airbag wiring  
can affect the operation of the airbag system.  
If the vehicle has rollover roof-rail airbags, see  
additional important information.  
Q: Because I have a disability, I have to get my  
vehicle modified. How can I find out whether  
this will affect my airbag system?  
In addition, the vehicle may have a passenger  
sensing system for the right front passenger  
position, which includes sensors that are part of  
the passenger seat. The passenger sensing system  
may not operate properly if the original seat trim is  
replaced with non-GM covers, upholstery or trim,  
or with GM covers, upholstery or trim designed for a  
different vehicle. Any object, such as an aftermarket  
seat heater or a comfort enhancing pad or device,  
installed under or on top of the seat fabric, could also  
interfere with the operation of the passenger sensing  
A: If you have questions, call Customer Assistance.  
The phone numbers and addresses for Customer  
Assistance are in Step Two of the Customer  
Satisfaction Procedure in this manual. See  
In addition, your dealer/retailer and the service manual  
have information about the location of the airbag sensors,  
sensing and diagnostic module and airbag wiring.

Airbags  
Restraint System Check  
The airbag system does not need regularly scheduled  
maintenance or replacement. Make sure the airbag  
readiness light is working. See Airbag Readiness Light  
on page 3-27 for more information.  
Checking the Restraint Systems  
Safety Belts  
Notice: If an airbag covering is damaged, opened,  
or broken, the airbag may not work properly.  
Do not open or break the airbag coverings. If there  
are any opened or broken airbag covers, have  
the airbag covering and/or airbag module replaced.  
For the location of the airbag modules, see What  
Makes an Airbag Inflate? on page 1-63. See  
your dealer/retailer for service.  
Now and then, check that the safety belt reminder light,  
safety belts, buckles, latch plates, retractors, and  
anchorages are all working properly.  
Look for any other loose or damaged safety belt system  
parts that might keep a safety belt system from doing  
its job. See your dealer/retailer to have it repaired.  
Torn or frayed safety belts may not protect you  
in a crash. They can rip apart under impact forces.  
If a belt is torn or frayed, get a new one right away.  
Make sure the safety belt reminder light is working.  
See Safety Belt Reminders on page 3-26 for more  
information.  
Keep safety belts clean and dry. See Care of Safety  
Belts on page 5-102.

If the vehicle has the LATCH system and it was being  
used during a crash, you may need new LATCH  
system parts.  
Replacing Restraint System Parts  
After a Crash  
New parts and repairs may be necessary even if the  
safety belt or LATCH system (if equipped), was  
not being used at the time of the crash.  
{ CAUTION:  
If an airbag inflates, you will need to replace airbag  
system parts. See the part on the airbag system earlier  
in this section.  
A crash can damage the restraint systems in your  
vehicle. A damaged restraint system may not  
properly protect the person using it, resulting in  
serious injury or even death in a crash. To help  
make sure your restraint systems are working  
properly after a crash, have them inspected and  
any necessary replacements made as soon as  
possible.  
Have the safety belt pretensioners checked if the  
vehicle has been in a crash, if the airbag readiness light  
stays on after the vehicle is started, or while you are  
driving. See Airbag Readiness Light on page 3-27.  
If the vehicle has been in a crash, do you need new  
safety belts or LATCH system (if equipped) parts?  
After a very minor crash, nothing may be necessary.  
But the safety belt assemblies that were used during  
any crash may have been stressed or damaged.  
See your dealer/retailer to have the safety belt  
assemblies inspected or replaced.

PASS-Key® III+ Electronic  
Immobilizer  
The PASS-Key III+ system operates on a radio  
frequency subject to Federal Communications  
Commission (FCC) Rules and with Industry Canada.  
PASS-Key® III+ Electronic  
Immobilizer Operation  
Your vehicle is equipped with the PASS-Key® III+  
(Personalized Automotive Security System)  
theft-deterrent system. PASS-Key® III+ is a passive  
theft-deterrent system.  
This device complies with Part 15 of the FCC Rules.  
Operation is subject to the following two conditions:  
The system is automatically armed when the key is  
removed from the ignition.  
1. This device may not cause harmful interference.  
You do not have to manually arm or disarm the system.  
2. This device must accept any interference received,  
including interference that may cause undesired  
operation.  
The security light will come on if there is a problem  
with arming or disarming the theft-deterrent system.  
When the PASS-Key® III+ system senses that someone  
is using the wrong key, it shuts down the vehicle’s  
starter and fuel systems. The starter will not work and  
fuel will stop being delivered to the engine. Anyone  
using a trial-and-error method to start the vehicle will be  
discouraged because of the high number of electrical  
key codes.  
This device complies with RSS-210 of Industry Canada.  
Operation is subject to the following two conditions:  
1. This device may not cause interference.  
2. This device must accept any interference received,  
including interference that may cause undesired  
operation of the device.  
Changes or modifications to this system by other than  
an authorized service facility could void authorization to  
use this equipment.  
PASS-Key III+ uses a radio frequency transponder in  
the key that matches a decoder in the vehicle.  
2-17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
If the engine does not start and the security message  
comes on, the key may have a damaged transponder.  
Turn the ignition off and try again.  
To program the new key:  
1. Verify the new key has 1 stamped on it.  
2. Insert the original, already programmed key  
into the ignition lock cylinder and start the engine.  
If the engine will not start, see your dealer/retailer  
for service.  
If the engine still does not start, and the key appears to  
be undamaged, try another ignition key. At this time,  
you may also want to check the instrument panel  
PASS KEY fuse. If the engine still does not start with  
the other key, your vehicle needs service. If your vehicle  
does start, the first key may be faulty. See your  
dealer/retailer or a locksmith who can service the  
PASS-Key® III+ to have a new key made. See Fuses  
and Circuit Breakers on page 5-108.  
3. After the engine has started, turn the key to  
LOCK/OFF and remove the key.  
4. Insert the key to be programmed and turn it to  
ON/RUN within 10 seconds of removing the  
previous key.  
It is possible for the PASS-Key® III+ decoder to learn  
the transponder value of a new or replacement key.  
Up to 10 keys may be programmed for the vehicle.  
This procedure is for learning additional keys only. If all  
the currently programmed keys are lost or do not  
operate, you must see your dealer/retailer or a locksmith  
who can service PASS-Key® III+ to have keys made  
and programmed to the system.  
The security message will turn off once the key has  
been programmed. It may not be apparent that  
the security message went on due to how quickly  
the key is programmed.  
5. Repeat Steps 1 through 4 if additional keys are to  
be programmed.  
If you lose or damage a PASS-Key® III+ key,  
see your dealer/retailer or a locksmith who can  
service PASS-Key® III+ to have a new key made.  
See your dealer/retailer or a locksmith who can service  
PASS-Key® III+ to get a new key blank that is cut  
exactly as the ignition key that operates the system.  
Do not leave the key or device that disarms or  
deactivates the theft deterrent system in the vehicle.

Ignition Positions  
Starting and Operating  
Your Vehicle  
The ignition switch has  
four different positions.  
New Vehicle Break-In  
Notice: The vehicle does not need an elaborate  
break-in. But it will perform better in the long run if  
you follow these guidelines:  
Keep your speed at 55 mph (88 km/h) or less for  
the first 500 miles (805 km).  
Do not drive at any one constant speed, fast or  
slow, for the first 500 miles (805 km). Do not  
make full-throttle starts. Avoid downshifting to  
brake or slow the vehicle.  
To shift out of P (Park), the ignition must be in ON/RUN  
and the regular brake pedal applied.  
Avoid making hard stops for the first 200 miles  
(322 km) or so. During this time the new brake  
linings are not yet broken in. Hard stops  
A (LOCK/OFF): This position locks the ignition and  
transmission. You will only be able to remove the key  
when the ignition is turned to LOCK/OFF.  
with new linings can mean premature wear and  
earlier replacement. Follow this breaking-in  
guideline every time you get new brake linings.  
Notice: Using a tool to force the key to turn in the  
ignition could cause damage to the switch or break  
the key. Use the correct key, make sure it is all the  
way in, and turn it only with your hand. If the key  
cannot be turned by hand, see your dealer/retailer.  
Do not tow a trailer during break-in. See Towing  
a Trailer on page 4-27 for the trailer towing  
capabilities of the vehicle and more information.  
Following break-in, engine speed and load can be  
gradually increased.

B (ACC/ACCESSORY): This is the position in which  
you can operate things like the radio and the windshield  
wipers when the engine is off.  
Retained Accessory Power (RAP)  
These vehicle accessories can be used for up to  
10 minutes after the engine is turned off:  
C (ON/RUN): This position can be used to operate the  
electrical accessories and to display some instrument  
panel cluster warning and indicator lights. The switch  
stays in this position when the engine is running.  
Audio System  
Power Windows (if equipped)  
These features will work when the ignition key is in  
ON/RUN or ACC/ACCESSORY. Once the key is turned  
from ON/RUN to LOCK/OFF, power to the radio will  
continue to work 10 minutes or until the driver door is  
opened. The power windows will continue to work for  
up to 10 minutes or until any door is opened.  
If you leave the key in the ACC/ACCESSORY or  
ON/RUN position with the engine off, the battery could  
be drained. You may not be able to start the vehicle  
if the battery is allowed to drain for an extended period  
of time.  
D (START): This is the position that starts the engine.  
When the engine starts, release the key. The ignition  
switch returns to ON/RUN for driving.  
Starting the Engine  
If the vehicle has the DURAMAX® Diesel engine, see  
the DURAMAX® Diesel manual for more information.

2. If the engine does not start after 5-10 seconds,  
especially in very cold weather (below 0°F  
or 18°C), it could be flooded with too much  
gasoline. Try pushing the accelerator pedal all  
the way to the floor and holding it there as you  
hold the key in START for up to 15 seconds.  
Wait at least 15 seconds between each try,  
to allow the cranking motor to cool down.  
When the engine starts, let go of the key and  
accelerator. If the vehicle starts briefly but then  
stops again, do the same thing. This clears the extra  
gasoline from the engine. Do not race the engine  
immediately after starting it. Operate the engine and  
transmission gently until the oil warms up and  
lubricates all moving parts.  
Starting Procedure  
1. With your foot off the accelerator pedal, turn the  
ignition key to START. When the engine starts,  
let go of the key. The idle speed will go down as  
your engine gets warm. Do not race the engine  
immediately after starting it. Operate the engine and  
transmission gently to allow the oil to warm up  
and lubricate all moving parts.  
The vehicle has a Computer-Controlled Cranking  
System. This feature assists in starting the  
engine and protects components. If the ignition key  
is turned to the START position, and then  
released when the engine begins cranking, the  
engine will continue cranking for a few seconds or  
until the vehicle starts. If the engine does not  
start and the key is held in START for many  
seconds, cranking will be stopped after 15 seconds  
to prevent cranking motor damage. To prevent  
gear damage, this system also prevents cranking if  
the engine is already running. Engine cranking  
can be stopped by turning the ignition switch to the  
ACC/ACCESSORY or LOCK/OFF position.  
Notice: The engine is designed to work with the  
electronics in the vehicle. If you add electrical parts  
or accessories, you could change the way the  
engine operates. Before adding electrical equipment,  
check with your dealer/retailer. If you do not, the  
engine might not perform properly. Any resulting  
damage would not be covered by the vehicle  
warranty.  
Notice: Cranking the engine for long periods of  
time, by returning the key to the START position  
immediately after cranking has ended, can overheat  
and damage the cranking motor, and drain the  
battery. Wait at least 15 seconds between each try,  
to let the cranking motor cool down.

Engine Coolant Heater  
{ CAUTION:  
If the vehicle has the DURAMAX Diesel engine, see the  
DURAMAX Diesel manual for more information.  
Plugging the cord into an ungrounded outlet could  
cause an electrical shock. Also, the wrong kind of  
extension cord could overheat and cause a fire.  
You could be seriously injured. Plug the cord into  
a properly grounded three-prong 110-volt AC  
outlet. If the cord will not reach, use a heavy-duty  
three-prong extension cord rated for at least  
15 amps.  
The engine coolant heater can provide easier starting  
and better fuel economy during engine warm-up in  
cold weather conditions at or below 0°F (18°C).  
Vehicles with an engine coolant heater should be  
plugged in at least four hours before starting. An internal  
thermostat in the plug-end of the cord may exist  
which will prevent engine coolant heater operation at  
temperatures above 0°F (18°C).  
To Use the Engine Coolant Heater  
4. Before starting the engine, be sure to unplug and  
store the cord as it was before to keep it away  
from moving engine parts and prevent damage.  
1. Turn off the engine.  
2. Open the hood and unwrap the electrical cord.  
The cord for the engine coolant heater is located  
on the driver side of the engine compartment and is  
attached to the hose for the power steering  
reservoir.  
The length of time the heater should remain plugged in  
depends on several factors. Ask a dealer/retailer in  
the area where you will be parking the vehicle for the  
best advice on this.  
3. Plug it into a normal, grounded 110-volt AC outlet.

Automatic Transmission Operation  
{ CAUTION:  
It is dangerous to get out of the vehicle if the shift  
lever is not fully in P (Park) with the parking brake  
firmly set. The vehicle can roll.  
Do not leave the vehicle when the engine is  
running unless you have to. If you have left the  
engine running, the vehicle can move suddenly.  
You or others could be injured. To be sure the  
vehicle will not move, even when you are on fairly  
level ground, always set the parking brake and  
move the shift lever to P (Park). See Shifting Into  
Park on page 2-29. If you are pulling a trailer,  
see Towing a Trailer on page 4-27.  
There are several different positions for your shift lever.  
P (Park): This position locks your rear wheels. It is  
the best position to use when you start the engine  
because the vehicle cannot move easily.  
Make sure the shift lever is fully in P (Park) before  
starting the engine. The vehicle has an automatic  
transmission shift lock control system. You must first  
press the brake pedal before you can shift from P (Park)  
with the ignition in ON/RUN.  
2-24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
If you cannot shift out of P (Park), ease pressure on the  
shift lever and push the shift lever all the way into  
P (Park) as you maintain brake application. Then move  
the shift lever into another gear. See Shifting Out of  
Park on page 2-30.  
{ CAUTION:  
Shifting into a drive gear while the engine is  
running at high speed is dangerous. Unless your  
foot is firmly on the brake pedal, the vehicle could  
move very rapidly. You could lose control and hit  
people or objects. Do not shift into a drive gear  
while the engine is running at high speed.  
R (Reverse): Use this gear to back up.  
Notice: Shifting to R (Reverse) while the vehicle is  
moving forward could damage the transmission.  
The repairs would not be covered by the vehicle  
warranty. Shift to R (Reverse) only after the vehicle  
is stopped.  
Notice: Shifting out of P (Park) or N (Neutral) with  
the engine running at high speed may damage  
the transmission. The repairs would not be covered  
by the vehicle warranty. Be sure the engine is  
not running at high speed when shifting the vehicle.  
To rock the vehicle back and forth to get out of snow,  
ice or sand without damaging the transmission, see  
page 4-18.  
N (Neutral): In this position, the engine does not  
connect with the wheels. To restart the engine when  
the vehicle is already moving, use N (Neutral) only.  
Also, use N (Neutral) when the vehicle is being towed.  
2-25  
Download from Www.Somanuals.com. All Manuals Search And Download.  
D (Drive): This position is for normal driving. It provides  
the best fuel economy. If you need more power for  
passing, and you are:  
2 (Second): This position reduces vehicle speed even  
more than 3 (Third) without using the brakes. You can  
use 2 (Second) on hills. It can help control vehicle speed  
as you go down steep mountain roads, but then you  
would also want to use the brakes off and on.  
Going less than about 35 mph (55 km/h), push the  
accelerator pedal about halfway down.  
You may use this feature for reducing torque to the rear  
wheels when you are trying to start the vehicle from  
a stop on slippery road surfaces.  
Going about 35 mph (55 km/h) or more, push the  
accelerator all the way down.  
You will shift down to the next gear and have more  
power.  
1 (First): This position reduces vehicle speed even  
more than 2 (Second) without using the brakes. You can  
use it on very steep hills, or in deep snow or mud.  
If the shift lever is put in 1 (First) while the vehicle is  
moving forward, the transmission will not shift into first  
gear until the vehicle is going slowly enough.  
Downshifting the transmission in slippery road conditions  
could result in skidding, see “Skidding” under Loss of  
Control on page 4-11.  
3 (Third): This position is also used for normal driving.  
However it reduces vehicle speed more than D (Drive)  
without using the brakes. You might choose 3 (Third)  
instead of D (Drive) when driving on hilly, winding roads,  
when towing a trailer, so there is less shifting between  
gears and when going down a steep hill.  
Notice: Spinning the tires or holding the vehicle  
in one place on a hill using only the accelerator  
pedal may damage the transmission. The repair will  
not be covered by the vehicle warranty. If you are  
stuck, do not spin the tires. When stopping on a hill,  
use the brakes to hold the vehicle in place.  
You should use 3 (Third) (or a lower gear as needed)  
when towing a trailer to minimize heat build-up and  
extend the life of the transmission.

Tow/Haul Mode  
Tow/haul is designed to assist while the vehicle is  
pulling a large or heavy load or trailer. Tow/haul is most  
useful while pulling such a load in rolling terrain, in  
stop-and-go traffic, or when you need improved  
low-speed control, such as when parking. The purpose  
of the tow/haul mode is to:  
Reduce the frequency and improve the predictability  
of transmission shifts,  
Tow/haul mode will turn off automatically when the  
ignition is turned off. See Tow/Haul Mode Light  
on page 3-40.  
provide the same solid shift feel when pulling a  
heavy load as when the vehicle is unloaded,  
Tow/haul is most effective when the vehicle and trailer  
combined weight is at least 75 percent of the vehicle’s  
Gross Combined Weight Rating (GCWR). See “Weight  
of the Trailer” later in this section.  
improve control of vehicle speed while requiring  
less throttle pedal activity.  
Press this button located  
to the right of the steering  
wheel on the instrument  
panel to turn tow/haul  
mode on and off.  
Driving with tow/haul activated without a heavy load will  
cause reduced fuel economy and unpleasant engine  
and transmission driving characteristics, but will not  
cause damage.

The shift lock control system is designed to do the  
following:  
Torque Lock  
If you are parking on a hill and you do not shift the  
vehicle into P (Park) properly, the weight of the vehicle  
may put too much force on the parking pawl in the  
transmission. You may find it difficult to pull the shift  
lever out of P (Park). This is called torque lock.  
To prevent torque lock, set the parking brake and  
then shift into P (Park) properly before you leave the  
driver seat. To find out how, see Shifting Into Park  
on page 2-29.  
Prevent the ignition key from being removed  
unless the shift lever is in P (Park).  
Prevent movement of the shift lever out of P (Park),  
unless the ignition is in ON/RUN and the regular  
brake pedal is applied.  
The shift lock control system is always functional  
except in the case of a dead battery or low voltage  
(less than 9 V) battery.  
When you are ready to drive, move the shift lever out of  
P (Park) before you release the parking brake.  
If the vehicle has an uncharged battery or a battery with  
low voltage, try charging or jump starting the battery.  
See Jump Starting on page 5-41 for more information.  
If torque lock does occur, you may need to have another  
vehicle push yours a little uphill to take some of the  
pressure from the parking pawl in the transmission,  
so you can pull the shift lever out of P (Park).  
To shift out of P (Park) use the following:  
1. Apply the brake pedal.  
2. Move the shift lever to the desired position.  
If you still are unable to shift out of P (Park):  
1. Ease the pressure on the shift lever.  
Shifting Out of Park  
The vehicle has an automatic transmission shift lock  
control system. You have to fully apply the brakes before  
you can shift from P (Park) when the ignition is in  
page 2-24.  
2. While holding down the brake pedal, push the shift  
lever all the way into P (Park)  
3. Move the shift lever to the desired position.  
If you are still having a problem shifting, then have the  
vehicle serviced.

Cruise control can be dangerous on slippery  
roads. On such roads, fast changes in tire traction  
can cause excessive wheel slip, and you could  
lose control. Do not use cruise control on slippery  
roads.  
In freezing weather, do not use your washer until  
the windshield is warmed. Otherwise the washer  
fluid can form ice on the windshield, blocking  
your vision.  
With cruise control, a speed of about 25 mph (40 km/h)  
or more can be maintained without keeping your foot  
on the accelerator. Cruise control does not work  
at speeds below about 25 mph (40 km/h).  
When the brakes are applied, cruise control is turned off.  
If the vehicle has StabiliTrak®, and the system begins  
to limit wheel spin, cruise control will automatically  
disengage. See StabiliTrak® System on page 4-6.  
When road conditions allow the cruise control to be  
safely used again, it can be turned back on.

Daytime Running Lamps (DRL)  
Automatic Headlamp System  
Daytime Running Lamps (DRL) can make it easier  
for others to see the front of your vehicle during the day.  
Fully functional daytime running lamps are required  
on all vehicles first sold in Canada.  
When it is dark enough outside and the headlamp  
switch is in AUTO, the automatic headlamp system turns  
on the headlamps, along with the taillamps, sidemarker,  
parking lamps, roof marker lamps, and the instrument  
panel lights. The radio lights will also be dim.  
The DRL system comes on in daylight when the  
following conditions are met:  
To turn off the automatic headlamp system, turn the  
exterior lamps switch to the off position and then release.  
For vehicles first sold in Canada, the transmission must  
be in the P (Park) position, before the automatic  
headlamp system can be turned off.  
The ignition is on.  
The exterior lamps control is in the AUTO position.  
The shift lever is not in P (Park).  
The light sensor determines it is daytime.  
The vehicle has a light sensor located on the top of  
the instrument panel. Do not cover the sensor or  
the system will come on whenever the ignition is on.  
When the DRL are on, the taillamps, sidemarker,  
instrument panel and other lamps will not be on.  
The system may also turn on the headlamps when  
driving through a parking garage or tunnel.  
The automatic headlamp system automatically switches  
from DRL to the headlamps depending on the darkness  
of the surroundings.  
There is a delay in the transition between the daytime  
and nighttime operation of the Daytime Running  
To turn off the DRL, turn the exterior lamp control to the

If the vehicle is started in a dark garage, the automatic  
headlamp system comes on immediately. Once the  
vehicle leaves the garage, it takes approximately  
30 seconds for the automatic headlamp system to  
change to DRL if it is light outside. During that delay,  
the instrument panel cluster may not be as bright  
as usual. Make sure the instrument panel brightness  
control is in the full bright position. See Instrument  
Panel Brightness on page 3-15.  
Dome Lamps  
The dome lamps come on when any door is opened.  
They turn off after all the doors are closed.  
The dome lamps can also be turned on by turning  
the instrument panel brightness knob, located on the  
instrument panel to the left of the steering column,  
clockwise to the farthest position. In this position,

The battery can be discharged at idle if the electrical  
loads are very high. This is true for all vehicles.  
This is because the generator (alternator) may not  
be spinning fast enough at idle to produce all the  
power that is needed for very high electrical loads.  
Entry/Exit Lighting  
The vehicle has an illuminated entry/exit feature.  
The dome lamps come on if the dome override button is  
in the out position, when a door is opened or the key  
is removed from the ignition.  
A high electrical load occurs when several of the  
following are on, such as: headlamps, high beams, fog  
lamps, rear window defogger, climate control fan at  
high speed, heated seats, engine cooling fans, trailer  
loads, and loads plugged into accessory power outlets.  
Reading Lamps  
For vehicles with reading lamps, press the button  
located next to each lamp to turn it on or off.  
EPM works to prevent excessive discharge of the  
battery. It does this by balancing the generator’s output  
and the vehicle’s electrical needs. It can increase  
engine idle speed to generate more power, whenever  
needed. It can temporarily reduce the power demands  
of some accessories.  
The vehicle may also have reading lamps in other  
locations. The lamps cannot be adjusted.  
Electric Power Management  
Normally, these actions occur in steps or levels, without  
being noticeable. In rare cases at the highest levels of  
corrective action, this action may be noticeable to the  
driver. If so, a Driver Information Center (DIC) message  
might be displayed, such as BATTERY SAVER ACTIVE,  
BATTERY VOLTAGE LOW, or LOW BATTERY. If this  
message is displayed, it is recommended that the driver  
reduce the electrical loads as much as possible. See DIC  
Warnings and Messages on page 3-48.  
The vehicle has Electric Power Management (EPM)  
that estimates the battery’s temperature and state  
of charge. It then adjusts the voltage for best  
performance and extended life of the battery.  
When the battery’s state of charge is low, the voltage is  
raised slightly to quickly bring the charge back up. When  
the state of charge is high, the voltage is lowered slightly  
to prevent overcharging. If the vehicle has a voltmeter  
gage or a voltage display on the Driver Information  
Center (DIC), you may see the voltage move up or down.  
This is normal. If there is a problem, an alert will be  
displayed.

If it does not, have the vehicle serviced by your  
dealer/retailer.  
The light should go out once the engine starts. If it stays  
on, or comes on while driving, there could be a problem  
with the charging system. A charging system message  
in the Driver Information Center (DIC) can also appear.  
See DIC Warnings and Messages on page 3-48 for more  
information. This light could indicate that there are  
problems with a generator drive belt, or that there is an  
electrical problem. Have it checked right away. If the  
vehicle must be driven a short distance with the light on,  
turn off accessories, such as the radio and air  
conditioner.  
{ CAUTION:  
If the airbag readiness light ever comes on and  
stays on, it means that something may be wrong

Voltmeter Gage  
When the engine is not  
running, but the ignition  
is on, this gage shows the  
battery’s state of charge  
in DC volts.  
Readings in either warning zone indicate a possible  
problem in the electrical system. Have the vehicle  
serviced as soon as possible.  
Brake System Warning Light  
The vehicle’s hydraulic brake system is divided into  
two parts. If one part is not working, the other part  
can still work and stop the vehicle. For good braking,  
both need to work.  
If the warning light comes on, there could be a brake  
problem. Have the brake system inspected right away.  
When the engine is running, the gage shows the  
condition of the charging system. Readings between  
the low and high warning zones indicate the normal  
operating range.  
Readings in the low warning zone may occur when  
a large number of electrical accessories are operating  
in the vehicle and the engine is left at an idle for an  
extended period. This condition is normal since the  
charging system is not able to provide full power at  
engine idle. As engine speeds are increased, this  
condition should correct itself as higher engine speeds  
allow the charging system to create maximum power.

If the light comes on while driving, pull off the road and  
stop carefully. The pedal might be harder to push, or the  
pedal might go closer to the floor. It could take longer to  
stop. If the light is still on, have the vehicle towed for  
service. See Towing Your Vehicle on page 4-24.  
If it does not, have the vehicle serviced by your  
dealer/retailer. If the system is working normally the  
indicator light then goes off.  
{ CAUTION:  
If the ABS light stays on, turn the ignition off. If the  
light comes on while driving, stop as soon as it is safely  
possible and turn the ignition off. Then start the engine  
again to reset the system. If the ABS light stays on, or  
comes on again while driving, the vehicle needs service.  
If the regular brake system warning light is not on, the  
vehicle still has brakes, but not antilock brakes. If the  
regular brake system warning light is also on, the vehicle  
does not have antilock brakes and there is a problem with  
the regular brakes. See Brake System Warning Light on  
page 3-31.  
The brake system might not be working properly if  
the brake system warning light is on. Driving with  
the brake system warning light on can lead to a  
crash. If the light is still on after the vehicle has  
been pulled off the road and carefully stopped,  
have the vehicle towed for service.

StabiliTrak® Indicator Light  
Engine Coolant Temperature Gage  
For vehicles with the  
StabiliTrak® system,  
this light comes on or  
flashes, according to  
the description table for  
the StabiliTrak system.  
For more information, see StabiliTrak® System on  
page 4-6.  
United States  
Canada  
Three chimes sound if the light turns on and one chime  
if the light turns off.  
This gage shows the engine coolant temperature. It also  
provides an indicator of how hard the vehicle is working.  
During a majority of the operation, the gage will read  
210°F (100°C) or less. If the vehicle is pulling a load or  
going up hills, it is normal for the temperature to fluctuate  
and approach the 250°F (122°C) mark. If the gage  
reaches the 260°F (125°C) mark, it indicates that the  
cooling system is working beyond its capacity.  
If this light remains on steady, the vehicle needs to be  
taken in for service.

Tire Pressure Light  
For vehicles with a tire  
pressure monitoring  
system, this light comes on  
briefly when the engine  
is started.  
This indicates that there could be a problem with the  
Tire Pressure Monitor System. The light flashes for about  
a minute and stays on steady for the remainder of the  
ignition cycle. This sequence repeats with every ignition  
cycle. See Tire Pressure Monitor System on page 5-66  
for more information.  
Malfunction Indicator Lamp  
Check Engine Light  
It provides information about tire pressures and the  
Tire Pressure Monitoring System.  
When the Light is On Steady  
A computer system called OBD II (On-Board  
Diagnostics-Second Generation) monitors operation  
of the fuel, ignition, and emission control systems.  
It ensures that emissions are at acceptable levels  
for the life of the vehicle, helping to produce a cleaner  
environment.  
This indicates that one or more of the tires is significantly  
underinflated.  
A tire pressure message in the Driver Information  
Center (DIC), can accompany the light. See DIC  
Warnings and Messages on page 3-48 for more  
information. Stop and check the tires as soon as it is  
safe to do so. If a tire is underinflated, inflate to the  
proper pressure. See Tires on page 5-55 for more  
information.  
This light should come on  
when the ignition is on, but  
the engine is not running,

If the check engine light comes on and stays on, while  
the engine is running, this indicates that there is an  
OBD II problem and service is required.  
This light comes on during a malfunction in one of  
two ways:  
Light Flashing: A misfire condition has been detected.  
A misfire increases vehicle emissions and could damage  
the emission control system on the vehicle. Diagnosis  
and service might be required.  
Malfunctions often are indicated by the system before  
any problem is apparent. Being aware of the light  
can prevent more serious damage to the vehicle.  
This system assists the service technician in correctly  
diagnosing any malfunction.  
To prevent more serious damage to the vehicle:  
Reduce vehicle speed.  
Notice: If the vehicle is continually driven with  
this light on, after a while, the emission controls  
might not work as well, the vehicle’s fuel economy  
might not be as good, and the engine might not  
run as smoothly. This could lead to costly repairs  
that might not be covered by the vehicle warranty.  
Avoid hard accelerations.  
Avoid steep uphill grades.  
If towing a trailer, reduce the amount of cargo being  
hauled as soon as it is possible.  
Notice: Modifications made to the engine,  
transmission, exhaust, intake, or fuel system  
of the vehicle or the replacement of the original  
tires with other than those of the same Tire  
Performance Criteria (TPC) can affect the vehicle’s  
emission controls and can cause this light to come  
on. Modifications to these systems could lead to  
costly repairs not covered by the vehicle warranty.  
This could also result in a failure to pass a required  
Emission Inspection/Maintenance test. See  
If the light continues to flash, when it is safe to do so,  
stop the vehicle. Find a safe place to park the vehicle.  
Turn the key off, wait at least 10 seconds, and restart  
the engine. If the light is still flashing, follow the previous  
steps and see your dealer/retailer for service as soon  
as possible.

Light On Steady: An emission control system  
malfunction has been detected on the vehicle.  
Diagnosis and service might be required.  
Make sure to fuel the vehicle with quality fuel. Poor  
fuel quality causes the engine not to run as efficiently  
as designed and can cause: stalling after start-up,  
stalling when the vehicle is changed into gear,  
misfiring, hesitation on acceleration, or stumbling on  
acceleration. These conditions might go away once  
the engine is warmed up.  
An emission system malfunction might be corrected by  
doing the following:  
Make sure the fuel cap is fully installed. See Filling  
the Tank on page 5-10. The diagnostic system  
can determine if the fuel cap has been left off or  
improperly installed. A loose or missing fuel cap  
allows fuel to evaporate into the atmosphere. A few  
driving trips with the cap properly installed should  
turn the light off.  
If one or more of these conditions occurs, change the  
fuel brand used. It will require at least one full tank of  
the proper fuel to turn the light off.  
See Gasoline Octane on page 5-6.  
If none of the above have made the light turn off, your  
dealer/retailer can check the vehicle. The dealer/retailer  
has the proper test equipment and diagnostic tools to  
fix any mechanical or electrical problems that might have  
developed.  
If the vehicle has been driven through a deep puddle  
of water, the vehicle’s electrical system might be wet.  
The condition is usually corrected when the electrical  
system dries out. A few driving trips should turn the  
light off.

Emissions Inspection and Maintenance  
Programs  
Oil Pressure Gage  
Some state/provincial and local governments have or  
might begin programs to inspect the emission control  
equipment on the vehicle. Failure to pass this inspection  
could prevent getting a vehicle registration.  
Here are some things to know to help the vehicle pass  
an inspection:  
The vehicle will not pass this inspection if the check  
engine light is on with the engine running, or if the  
key is in ON/RUN and the light is not on.  
United States  
Canada  
The vehicle will not pass this inspection if the OBD  
II (on-board diagnostic) system determines that  
critical emission control systems have not been  
completely diagnosed by the system. The vehicle  
would be considered not ready for inspection. This  
can happen if the battery has recently been replaced  
or if the battery has run down. The diagnostic system  
is designed to evaluate critical emission control  
systems during normal driving. This can take several  
days of routine driving. If this has been done and the  
vehicle still does not pass the inspection for lack of  
OBD II system readiness, your dealer/retailer can  
prepare the vehicle for inspection.  
The oil pressure gage shows the engine oil pressure in  
psi (pounds per square inch) when the engine is running.  
Canadian vehicles indicate pressure in kPa (kilopascals).  
Oil pressure may vary with engine speed, outside  
temperature and oil viscosity, but readings above the  
low pressure zone indicate the normal operating range.  
3-37

A reading in the low pressure zone may be caused by a  
dangerously low oil level or other problem causing low oil  
pressure. Check your oil as soon as possible.

Tow/Haul Mode Light  
The gage first indicates empty before the vehicle is out  
of fuel, and the fuel tank should be refueled soon.  
This light comes on when  
the Tow/Haul mode has  
been activated.  
Listed are four situations customers might experience  
with the fuel gage. None of these indicate a problem with  
the fuel gage:  
At the gas station, the fuel pump shuts off before  
the gage reads full.  
It takes a little more or less fuel to fill up than the  
fuel gage indicated. For example, the gage may  
have indicated the tank was half full, but it actually  
took a little more or less than half the tank’s  
capacity to fill the tank.  
For more information, see Tow/Haul Mode on page 2-27.  
Fuel Gage  
The gage moves a little while turning a corner or  
speeding up.  
The gage does not go back to empty when the  
ignition is turned off.  
If the vehicle has the DURAMAX Diesel engine, see the  
DURAMAX Diesel manual for more information.

To adjust for compass variance, use the following  
procedure:  
3. Press the set/reset button to scroll through and  
select the appropriate variance zone.  
4. Press the trip/fuel button until the vehicle heading,  
for example, N for North, is displayed in the DIC.  
Compass Variance (Zone) Procedure  
1. Do not set the compass zone when the vehicle is  
moving. Only set it when the vehicle is in P (Park).  
5. If calibration is necessary, calibrate the compass.  
See “Compass Calibration Procedure” following.  
Press the vehicle information button until  
PRESS V TO CHANGE COMPASS ZONE displays.  
Compass Calibration  
The compass can be manually calibrated. Only calibrate  
the compass in a magnetically clean and safe location,  
such as an open parking lot, where driving the vehicle  
in circles is not a danger. It is suggested to calibrate  
away from tall buildings, utility wires, manhole covers,  
or other industrial structures, if possible.  
If CAL should ever appear in the DIC display, the  
compass should be calibrated.  
If the DIC display does not show a heading, for  
example, N for North, or the heading does not change  
after making turns, there may be a strong magnetic field  
interfering with the compass. Such interference may be  
caused by a magnetic CB or cell phone antenna mount, a  
magnetic emergency light, magnetic note pad holder, or  
any other magnetic item. Turn off the vehicle, move the  
magnetic item, then turn on the vehicle and calibrate the  
compass.  
2. Find the vehicle’s current location and variance  
zone number on the map.  
Zones 1 through 15 are available.

DIC Warnings and Messages  
Compass Calibration Procedure  
Messages are displayed on the DIC to notify the driver  
that the status of the vehicle has changed and that some  
action may be needed by the driver to correct the  
condition. Multiple messages may appear one after  
another.  
1. Before calibrating the compass, make sure the  
compass zone is set to the variance zone in  
which the vehicle is located. See “Compass  
Variance (Zone) Procedure” earlier in this section.  
Do not operate any switches such as window,  
sunroof, climate controls, seats, etc. during  
the calibration procedure.  
Some messages may not require immediate action, but  
you can press any of the DIC buttons on the instrument  
panel to acknowledge that you received the messages  
and to clear them from the display.  
2. Press the vehicle information button until  
Some messages cannot be cleared from the DIC  
display because they are more urgent. These messages  
require action before they can be cleared. You should  
take any messages that appear on the display seriously  
and remember that clearing the messages will only  
make the messages disappear, not correct the problem.  
PRESS V TO CALIBRATE COMPASS displays.  
3. Press the set/reset button to start the compass  
calibration.  
4. The DIC will display CALIBRATING: DRIVE IN  
CIRCLES. Drive the vehicle in tight circles at  
less than 5 mph (8 km/h) to complete the calibration.  
The DIC will display CALIBRATION COMPLETE  
for a few seconds when the calibration is complete.  
The DIC display will then return to PRESS V TO  
CALIBRATE COMPASS.  
The following are the possible messages that can be

By default the radio shows the MP3 label on the left side  
of the screen but plays both file formats in the order  
in which they were recorded to the disc.  
BAND: Press to listen to the radio while a portable  
audio device is playing. The portable audio device  
continues playing, so you might want to stop it or  
turn it off.  
MP3 Format  
If you burn your own MP3 disc on a personal computer:  
Make sure the MP3 files are recorded on a CD-R  
or CD-RW disc.  
CD/AUX (CD/Auxiliary): Press to play a CD while a  
portable audio device is playing. Press again and  
the system begins playing audio from the connected  
portable audio player. If a portable audio player is  
not connected, the message No Aux Input Device  
displays.  
Do not mix standard audio and MP3 files on  
one disc.  
The CD player is able to read and play a maximum  
of 50 folders, 15 playlists, and 512 folders and files.  
Create a folder structure that makes it easy to find  
songs while driving. Organize songs by albums  
using one folder for each album. Each folder  
or album should contain 18 songs or less.  
Using an MP3  
MP3 CD-R or CD-RW Disc  
The radio plays MP3 files that were recorded on a  
CD-R or CD-RW disc. The files can be recorded with  
the following fixed bit rates: 32 kbps, 40 kbps, 56 kbps,  
64 kbps, 80 kbps, 96 kbps, 112 kbps, 128 kbps,  
160 kbps, 192 kbps, 224 kbps, 256 kbps, and 320 kbps  
or a variable bit rate. Song title, artist name, and album  
are available for display by the radio when recorded using  
ID3 tags version 1 and 2.  
Avoid subfolders. The system can support up to  
eight subfolders deep, however, keep the total  
number of folders to a minimum in order to reduce  
the complexity and confusion in trying to locate  
a particular folder during playback.  
Make sure playlists have a .mp3 or .wpl extension  
(other file extensions might not work).

Minimize the length of the file, folder, or playlist  
names. Long file, folder, or playlist names, or a  
combination of a large number of files and folders,  
or playlists could cause the player to be unable  
to play up to the maximum number of files, folders,  
playlists, or sessions. If you wish to play a large  
number of files, folders, playlists or sessions,  
minimize the length of the file, folder, or playlist  
name. Long names also take up more space on  
the display, potentially getting cut off.  
Root Directory  
The root directory of the CD-R or CD-RW is treated as a  
folder. If the root directory has compressed audio files,  
the directory displays as the CD label. All files contained  
directly under the root directory are accessed prior to any  
root directory folders. However, playlists (Px) are always  
accessed before root folders or files.  
If a disc contains both uncompressed CD audio (.CDA)  
and MP3 files, a folder under the root directory called  
CD accesses all of the CD audio tracks on the disc.  
Finalize the audio disc before you burn it. Trying to  
add music to an existing disc could cause the disc  
not to function in the player.  
Empty Directory or Folder  
If a root directory or a folder exists somewhere in the file  
structure that contains only folders/subfolders and no  
compressed files directly beneath them, the player  
advances to the next folder in the file structure that  
contains compressed audio files. The empty folder  
does not display.  
Playlists can be changed by using the S c (previous)  
and c T (next) folder buttons, the f knob, or the  
©SEEK ¨ arrows. You can also play an MP3 CD-R  
or CD-RW that was recorded using no file folders.  
If a CD-R or CD-RW contains more than the maximum  
of 50 folders, 15 playlists, and 512 folders and files,  
the player lets you access and navigate up to the  
maximum, but all items over the maximum are not  
accessible.  
No Folder  
When the CD contains only compressed files, the files  
are located under the root folder. The next and previous  
folder function does not display on a CD that was  
recorded without folders or playlists.  
When the CD contains only playlists and compressed  
audio files, but no folders, all files are located under the  
root folder. The folder down and up buttons search  
playlists (Px) first and then goes to the root folder.

Order of Play  
Preprogrammed Playlists  
Preprogrammed playlists that were created using  
WinAmp™, MusicMatch™, or Real Jukebox™ software  
can be accessed, however, they cannot be edited  
using the radio. These playlists are treated as special  
folders containing compressed audio song files.  
Tracks recorded to the CD-R or CD-RW are played in  
the following order:  
Play begins from the first track in the first playlist  
and continues sequentially through all tracks in  
each playlist. When the last track of the last playlist  
has played, play continues from the first track of  
the first playlist.  
Playing an MP3  
Insert a CD-R or CD-RW partway into the slot (Single  
CD Player), or press the load button and wait for the  
message to insert disc (Six-Disc CD Player), label side  
up. The player pulls it in, and the CD-R or CD-RW should  
begin playing.  
Play begins from the first track in the first folder  
and continues sequentially through all tracks in each  
folder. When the last track of the last folder has  
played, play continues from the first track of the  
first folder.  
If the ignition or radio is turned off with a CD-R or  
CD-RW in the player, it stays in the player. When the  
ignition or radio is turned on, the CD-R or CD-RW starts  
to play where it stopped, if it was the last selected  
audio source.  
When play enters a new folder, the display does not  
automatically show the new folder name unless you have  
chosen the folder mode as the default display. The new  
track name displays.  
As each new track starts to play, the track number and  
song title displays.  
File System and Naming  
The song name that displays is the song name that is  
contained in the ID3 tag. If the song name is not present  
in the ID3 tag, then the radio displays the file name  
without the extension (such as .mp3) as the track name.  
Z EJECT: Press this button to eject CD-R(s) or  
CD-RW(s). To eject the CD-R or CD-RW that is currently  
playing, press and release this button. A beep sounds  
and Ejecting Disc displays. Once the disc is ejected,  
Remove Disc displays. The CD-R or CD-RW can be  
removed. If the CD-R or CD-RW is not removed, after  
several seconds, the CD-R or CD-RW automatically pulls  
back into the player and begins playing.  
Track names longer than 32 characters or four pages  
are shortened. Parts of words on the last page of  
text and the extension of the filename does not display.

Cellular Phone Usage  
Radio Reception  
Cellular phone usage may cause interference with the  
vehicle’s radio. This interference may occur when making  
or receiving phone calls, charging the phone’s battery,  
or simply having the phone on. This interference causes  
an increased level of static while listening to the radio.  
If static is received while listening to the radio, unplug  
the cellular phone and turn it off.  
Frequency interference and static can occur during  
normal radio reception if items such as cell phone  
chargers, vehicle convenience accessories, and external  
electronic devices are plugged into the accessory  
power outlet. If there is interference or static, unplug  
the item from the accessory power outlet.  
AM  
Fixed Mast Antenna  
The range for most AM stations is greater than for FM,  
especially at night. The longer range can cause station  
frequencies to interfere with each other. For better radio  
reception, most AM radio stations boost the power levels  
during the day, and then reduce these levels during the  
night. Static can also occur when things like storms and  
power lines interfere with radio reception. When this  
happens, try reducing the treble on your radio.  
The fixed mast antenna can withstand most car washes  
without being damaged as long as it is securely attached  
to the base. If the mast becomes slightly bent, straighten  
it out by hand. If the mast is badly bent, replace it.  
Occasionally check to make sure the antenna is  
tightened to its base. If tightening is required, tighten  
by hand.  
FM Stereo  
FM stereo gives the best sound, but FM signals reach  
only about 10 to 40 miles (16 to 65 km). Tall buildings or  
hills can interfere with FM signals, causing the sound  
to fade in and out.

Defensive Driving  
Your Driving, the Road, and  
the Vehicle  
Defensive driving means “always expect the  
unexpected.” The first step in driving defensively  
is to wear your safety belt — See Safety Belts: They  
Are for Everyone on page 1-10.  
Driving for Better Fuel Economy  
Driving habits can affect fuel mileage. Here are some  
driving tips to get the best fuel economy possible.  
{ CAUTION:  
Avoid fast starts and accelerate smoothly.  
Brake gradually and avoid abrupt stops.  
Avoid idling the engine for long periods of time.  
Assume that other road users (pedestrians,  
bicyclists, and other drivers) are going to be  
careless and make mistakes. Anticipate what  
they might do and be ready. In addition:  
Allow enough following distance between you  
and the driver in front of you.  
When road and weather conditions are appropriate,  
use cruise control, if equipped.  
Always follow posted speed limits or drive more  
slowly when conditions require.  
Focus on the task of driving.  
Keep vehicle tires properly inflated.  
Driver distraction can cause collisions resulting in  
injury or possible death. These simple defensive  
driving techniques could save your life.  
Combine several trips into a single trip.  
Replace the vehicle’s tires with the same TPC Spec  
number molded into the tire’s sidewall near the size.  
Follow recommended scheduled maintenance.

For persons under 21, it is against the law in every  
U.S. state to drink alcohol. There are good medical,  
psychological, and developmental reasons for  
these laws.  
Drunk Driving  
{ CAUTION:  
The obvious way to eliminate the leading highway  
safety problem is for people never to drink alcohol  
and then drive.  
Drinking and then driving is very dangerous.  
Your reflexes, perceptions, attentiveness, and  
judgment can be affected by even a small amount  
of alcohol. You can have a serious — or even  
fatal — collision if you drive after drinking. Do not  
drink and drive or ride with a driver who has been  
drinking. Ride home in a cab; or if you are with a  
group, designate a driver who will not drink.  
Medical research shows that alcohol in a person’s  
system can make crash injuries worse, especially  
injuries to the brain, spinal cord, or heart. This means  
that when anyone who has been drinking — driver or  
passenger — is in a crash, that person’s chance of being  
killed or permanently disabled is higher than if the person  
had not been drinking.  
Control of a Vehicle  
Death and injury associated with drinking and driving is  
a global tragedy.  
The following three systems help to control the vehicle  
while driving — brakes, steering, and accelerator.  
At times, as when driving on snow or ice, it is easy to  
ask more of those control systems than the tires and road  
can provide. Meaning, you can lose control of the vehicle.  
Alcohol affects four things that anyone needs to drive a  
vehicle: judgment, muscular coordination, vision, and  
attentiveness.  
Police records show that almost 40 percent of all motor  
vehicle-related deaths involve alcohol. In most cases,  
these deaths are the result of someone who was drinking  
and driving. In recent years, more than 17,000 annual  
motor vehicle-related deaths have been associated with  
the use of alcohol, with about 250,000 people injured.

vehicle performance. See Accessories and Modifications

Avoid needless heavy braking. Some people drive  
in spurts — heavy acceleration followed by heavy  
braking — rather than keeping pace with traffic. This is a  
mistake. The brakes might not have time to cool between  
hard stops. The brakes will wear out much faster with a  
lot of heavy braking. Keeping pace with the traffic and  
allowing realistic following distances eliminates a lot of  
unnecessary braking. That means better braking and  
longer brake life.  
Braking  
See Brake System Warning Light on page 3-31.  
Braking action involves perception time and reaction  
time. Deciding to push the brake pedal is perception  
time. Actually doing it is reaction time.  
Average reaction time is about three-fourths of a  
second. But that is only an average. It might be less  
with one driver and as long as two or three seconds or  
more with another. Age, physical condition, alertness,  
coordination, and eyesight all play a part. So do alcohol,  
drugs, and frustration. But even in three-fourths of a  
second, a vehicle moving at 60 mph (100 km/h) travels  
66 feet (20 m). That could be a lot of distance in an  
emergency, so keeping enough space between  
the vehicle and others is important.  
If the engine ever stops while the vehicle is being  
driven, brake normally but do not pump the brakes.  
If the brakes are pumped, the pedal could get harder  
to push down. If the engine stops, there will still be  
some power brake assist but it will be used when the  
brake is applied. Once the power assist is used up,  
it can take longer to stop and the brake pedal will be  
harder to push.  
And, of course, actual stopping distances vary greatly  
with the surface of the road, whether it is pavement or  
gravel; the condition of the road, whether it is wet, dry,  
or icy; tire tread; the condition of the brakes; the weight  
of the vehicle; and the amount of brake force applied.  
Adding non-dealer/non-retailer accessories can affect  
vehicle performance. See Accessories and Modifications  
on page 5-3.

ABS can change the brake pressure to each wheel, as  
required, faster than any driver could. This can help  
the driver steer around the obstacle while braking hard.  
Antilock Brake System (ABS)  
This vehicle has the Antilock Brake System (ABS), an  
advanced electronic braking system that helps prevent a  
braking skid.  
As the brakes are applied, the computer keeps  
receiving updates on wheel speed and controls  
braking pressure accordingly.  
When the engine is started and the vehicle begins to  
drive away, ABS checks itself. A momentary motor or  
clicking noise might be heard while this test is going on.  
This is normal.  
Remember: ABS does not change the time needed  
to get a foot up to the brake pedal or always decrease  
stopping distance. If you get too close to the vehicle in  
front of you, there will not be enough time to apply the  
brakes if that vehicle suddenly slows or stops. Always  
leave enough room up ahead to stop, even with ABS.  
If there is a problem with  
the ABS, this warning light  
stays on. See Antilock  
Using ABS  
Do not pump the brakes. Just hold the brake pedal  
down firmly and let antilock work. The brakes might  
vibrate or some noise might be heard, but this is normal.  
page 3-32.  
Let us say the road is wet and you are driving safely.  
Suddenly, an animal jumps out in front of you. You slam  
on the brakes and continue braking. Here is what  
happens with ABS:  
Braking in Emergencies  
ABS allows the driver to steer and brake at the same  
time. In many emergencies, steering can help more than  
even the very best braking.  
A computer senses that the wheels are slowing down.  
If one of the wheels is about to stop rolling, the computer  
will separately work the brakes at each front wheel  
and at both rear wheels.

StabiliTrak® System  
Press and hold the  
StabiliTrak button located  
on the instrument panel  
for more than five seconds  
to turn off StabiliTrak  
and part of the traction  
control system.  
The vehicle may have a vehicle stability enhancement  
system called StabiliTrak. It is an advanced computer  
controlled system that assists the driver with directional  
control of the vehicle in difficult driving conditions.  
StabiliTrak activates when the computer senses a  
discrepancy between the intended path and the direction  
the vehicle is actually traveling. StabiliTrak selectively  
applies braking pressure at any one of the vehicle’s  
brakes to assist the driver with keeping the vehicle  
on the intended path.  
The StabiliTrak light comes  
on the instrument panel  
cluster when the system  
is turned off or requires  
service.  
When the vehicle is started and begins to move, the  
system performs several diagnostic checks to insure  
there are no problems. The system may be heard or  
felt while it is working. This is normal and does not  
mean there is a problem with the vehicle. The system  
should initialize before the vehicle reaches 20 mph  
(32 km/h). In some cases, it may take approximately  
2 miles (3.2 km) of driving before the system initializes.  
For more information, see StabiliTrak® Indicator Light  
on page 3-33.

For your safety, the system can only be disabled  
when the vehicle speed is less than 20 mph (32 km/h).  
Three chimes will be heard and the StabiliTrak light  
comes on.  
StabiliTrak System Operation  
The StabiliTrak system is normally on, except when  
the system is initializing or has been disabled with  
the StabiliTrak button. The StabiliTrak system will  
automatically activate to assist the driver in maintaining  
vehicle directional control in most driving conditions.  
When activated, the StabiliTrak system may reduce  
engine power to the wheels and apply braking to  
individual wheels as necessary to assist the driver  
with vehicle directional control. If cruise control is  
being used when StabiliTrak activates, the cruise  
control automatically disengages. The cruise control  
can be re-engaged when road conditions allow.  
See Cruise Control on page 3-9.  
To turn on the StabiliTrak system, press the StabiliTrak  
button again. StabiliTrak will automatically turn back on  
when the vehicle speed exceeds 20 mph (32 km/h).  
One chime is heard and the StabiliTrak light will turn off.  
When the StabiliTrak system has been turned off,  
system noises may still be heard as a result of the  
brake-traction control coming on.  
It is recommended to leave the system on for normal  
driving conditions, but it may be necessary to turn the  
system off if the vehicle is stuck in sand, mud, ice or  
snow, and you want to “rock” the vehicle to attempt to  
or Snow on page 4-18.  
The StabiliTrak system may also turn off automatically  
if it determines that a problem exists with the system.  
If the problem does not clear itself after restarting  
the vehicle, see your dealer/retailer for service.

Traction Control Operation  
Locking Rear Axle  
The traction control system is part of the StabiliTrak  
system. Traction control limits wheel spin by reducing  
engine power to the wheels and by applying brakes  
to each individual wheel as necessary.  
Vehicles with a locking rear axle can give more  
traction on snow, mud, ice, sand or gravel. It works  
like a standard axle most of the time, but when traction  
is low, this feature will allow the rear wheel with the most  
traction to move the vehicle.  
If the brake-traction control system activates constantly  
or if the brakes have heated up due to high speed  
braking, the brake-traction control will be automatically  
disabled. The system will come back on after the  
brakes have cooled. This can take up to two minutes  
or longer depending on brake usage.  
All-Wheel Drive (AWD) System  
If the vehicle has this feature, engine power is sent to  
all four wheels when extra traction is needed. This is  
like four-wheel drive, but there is no separate lever or  
switch to engage or disengage the front axle. It is fully  
automatic, and adjusts itself as needed for road  
conditions.  
The traction control system may activate on dry or  
rough roads or under conditions such as heavy  
acceleration while turning or abrupt upshifts/downshifts  
of the transmission. When this a reduction in acceleration  
may be noticed, or a noise or vibration may be heard.  
This is normal.  
Adding non-dealer/non-retailer accessories can affect  
the vehicle’s performance. See Accessories and  
Modifications on page 5-3 for more information.

Steering in Emergencies  
Steering  
There are times when steering can be more effective  
than braking. For example, you come over a hill and find  
a truck stopped in your lane, or a car suddenly pulls out  
from nowhere, or a child darts out from between parked  
cars and stops right in front of you. These problems  
can be avoided by braking — if you can stop in time.  
But sometimes you cannot stop in time because there is  
no room. That is the time for evasive action — steering  
around the problem.  
Power Steering  
If power steering assist is lost because the engine stops  
or the system is not functioning, the vehicle can be  
steered but it will take more effort.  
Steering Tips  
It is important to take curves at a reasonable speed.  
Traction in a curve depends on the condition of the tires  
and the road surface, the angle at which the curve is  
banked, and vehicle speed. While in a curve, speed is  
the one factor that can be controlled.  
The vehicle can perform very well in emergencies like  
these. First apply the brakes. See Braking on page 4-4.  
It is better to remove as much speed as possible from a  
collision. Then steer around the problem, to the left or  
right depending on the space available.  
If there is a need to reduce speed, do it before entering  
the curve, while the front wheels are straight.  
Try to adjust the speed so you can drive through  
the curve. Maintain a reasonable, steady speed.  
Wait to accelerate until out of the curve, and then  
accelerate gently into the straightaway.

Off-Road Recovery  
The vehicle’s right wheels can drop off the edge of a  
road onto the shoulder while driving.  
An emergency like this requires close attention and  
a quick decision. If holding the steering wheel at the  
recommended 9 and 3 o’clock positions, it can be turned  
a full 180 degrees very quickly without removing either  
hand. But you have to act fast, steer quickly, and just as  
quickly straighten the wheel once you have avoided the  
object.  
If the level of the shoulder is only slightly below the  
pavement, recovery should be fairly easy. Ease off the  
accelerator and then, if there is nothing in the way, steer  
so that the vehicle straddles the edge of the pavement.  
Turn the steering wheel 3 to 5 inches, 8 to 13 cm, (about  
one-eighth turn) until the right front tire contacts the  
pavement edge. Then turn the steering wheel to go  
straight down the roadway.  
The fact that such emergency situations are always  
possible is a good reason to practice defensive driving  
at all times and wear safety belts properly.

Skidding  
Passing  
In a skid, a driver can lose control of the vehicle.  
Defensive drivers avoid most skids by taking reasonable  
care suited to existing conditions, and by not overdriving  
those conditions. But skids are always possible.  
Passing another vehicle on a two-lane road can be  
dangerous. To reduce the risk of danger while passing:  
Look down the road, to the sides, and to crossroads  
for situations that might affect a successful pass.  
If in doubt, wait.  
The three types of skids correspond to the vehicle’s  
three control systems. In the braking skid, the wheels are  
not rolling. In the steering or cornering skid, too much  
speed or steering in a curve causes tires to slip and lose  
cornering force. And in the acceleration skid, too much  
throttle causes the driving wheels to spin.  
Watch for traffic signs, pavement markings, and  
lines that could indicate a turn or an intersection.  
Never cross a solid or double-solid line on your  
side of the lane.  
Do not get too close to the vehicle you want to  
pass. Doing so can reduce your visibility.  
If the vehicle starts to slide, ease your foot off the  
accelerator pedal and quickly steer the way you want  
the vehicle to go. If you start steering quickly enough,  
the vehicle may straighten out. Always be ready for  
a second skid if it occurs.  
Wait your turn to pass a slow vehicle.  
When you are being passed, ease to the right.  
Of course, traction is reduced when water, snow, ice,  
gravel, or other material is on the road. For safety, slow  
down and adjust your driving to these conditions. It is  
important to slow down on slippery surfaces because  
stopping distance is longer and vehicle control  
more limited.  
Loss of Control  
Let us review what driving experts say about what  
happens when the three control systems — brakes,  
steering, and acceleration — do not have enough friction  
where the tires meet the road to do what the driver has  
asked.  
In any emergency, do not give up. Keep trying to steer  
and constantly seek an escape route or area of less  
danger.

While driving on a surface with reduced traction,  
try your best to avoid sudden steering, acceleration,  
or braking, including reducing vehicle speed by shifting  
to a lower gear. Any sudden changes could cause the  
tires to slide. You might not realize the surface is slippery  
until the vehicle is skidding. Learn to recognize warning  
clues — such as enough water, ice, or packed snow on  
the road to make a mirrored surface — and slow down  
when you have any doubt.  
Reduce headlamp glare by adjusting the inside  
rearview mirror.  
Slow down and keep more space between you and  
other vehicles because headlamps can only light up  
so much road ahead.  
Watch for animals.  
When tired, pull off the road.  
Do not wear sunglasses.  
Remember: Any Antilock Brake System (ABS) helps  
avoid only the braking skid.  
Avoid staring directly into approaching headlamps.  
Keep the windshield and all glass on your vehicle  
clean — inside and out.  
Driving at Night  
Keep your eyes moving, especially during turns or  
curves.  
Night driving is more dangerous than day driving  
because some drivers are likely to be impaired — by  
alcohol or drugs, with night vision problems, or by  
fatigue.  
No one can see as well at night as in the daytime.  
But, as we get older, these differences increase.  
A 50-year-old driver might need at least twice as much  
light to see the same thing at night as a 20-year-old.  
Night driving tips include:  
Drive defensively.  
Do not drink and drive.

Hydroplaning  
Driving in Rain and on Wet Roads  
Hydroplaning is dangerous. Water can build up under  
your vehicle’s tires so they actually ride on the water.  
This can happen if the road is wet enough and you are  
going fast enough. When your vehicle is hydroplaning,  
it has little or no contact with the road.  
Rain and wet roads can reduce vehicle traction  
and affect your ability to stop and accelerate. Always  
drive slower in these types of driving conditions  
and avoid driving through large puddles and  
deep-standing or flowing water.  
There is no hard and fast rule about hydroplaning.  
The best advice is to slow down when the road is wet.  
{ CAUTION:  
Other Rainy Weather Tips  
Besides slowing down, other wet weather driving tips  
include:  
Wet brakes can cause crashes. They might not  
work as well in a quick stop and could cause  
pulling to one side. You could lose control of the  
vehicle.  
Allow extra following distance.  
Pass with caution.  
After driving through a large puddle of water or a  
car/vehicle wash, lightly apply the brake pedal until  
the brakes work normally.  
Keep windshield wiping equipment in good shape.  
Keep the windshield washer fluid reservoir filled.  
Have good tires with proper tread depth.  
Flowing or rushing water creates strong forces.  
Driving through flowing water could cause your  
vehicle to be carried away. If this happens, you  
and other vehicle occupants could drown. Do not  
ignore police warnings and be very cautious about  
trying to drive through flowing water.  
See Tires on page 5-55.  
Turn off cruise control.

Before Leaving on a Long Trip  
Highway Hypnosis  
To prepare your vehicle for a long trip, consider having  
it serviced by your dealer/retailer before departing.  
Always be alert and pay attention to your surroundings  
while driving. If you become tired or sleepy, find a  
safe place to park your vehicle and rest.  
Things to check on your own include:  
Other driving tips include:  
Windshield Washer Fluid: Reservoir full? Windows  
Keep the vehicle well ventilated.  
Keep interior temperature cool.  
clean — inside and outside?  
Wiper Blades: In good shape?  
Fuel, Engine Oil, Other Fluids: All levels checked?  
Lamps: Do they all work and are lenses clean?  
Keep your eyes moving — scan the road ahead  
and to the sides.  
Check the rearview mirror and vehicle instruments  
often.  
Tires: Are treads good? Are tires inflated to  
recommended pressure?  
Weather and Maps: Safe to travel? Have  
up-to-date maps?

Hill and Mountain Roads  
{ CAUTION:  
Driving on steep hills or through mountains is different  
than driving on flat or rolling terrain. Tips for driving  
in these conditions include:  
Coasting downhill in N (Neutral) or with the ignition  
off is dangerous. The brakes will have to do all the  
work of slowing down and they could get so hot  
that they would not work well. You would then  
have poor braking or even none going down a hill.  
You could crash. Always have the engine running  
and the vehicle in gear when going downhill.  
Keep the vehicle serviced and in good shape.  
Check all fluid levels and brakes, tires, cooling  
system, and transmission.  
Going down steep or long hills, shift to a  
lower gear.  
Stay in your own lane. Do not swing wide or cut  
across the center of the road. Drive at speeds  
that let you stay in your own lane.  
{ CAUTION:  
If you do not shift down, the brakes could get so  
hot that they would not work well. You would then  
have poor braking or even none going down a hill.  
You could crash. Shift down to let the engine  
assist the brakes on a steep downhill slope.  
Top of hills: Be alert — something could be in your  
lane (stalled car, accident).  
Pay attention to special road signs (falling rocks  
area, winding roads, long grades, passing or  
no-passing zones) and take appropriate action.

Blizzard Conditions  
Winter Driving  
Being stuck in snow can be in a serious situation.  
Stay with the vehicle unless there is help nearby.  
If possible, use the Roadside Assistance Program  
on page 7-8. To get help and keep everyone in the  
vehicle safe:  
Turn on the Hazard Warning Flashers on page 3-6.  
Tie a red cloth to an outside mirror.  
Driving on Snow or Ice  
Drive carefully when there is snow or ice between the  
tires and the road, creating less traction or grip. Wet ice  
can occur at about 32°F (0°C) when freezing rain begins  
to fall, resulting in even less traction. Avoid driving on wet  
ice or in freezing rain until roads can be treated with salt  
or sand.  
Drive with caution, whatever the condition. Accelerate  
gently so traction is not lost. Accelerating too quickly  
causes the wheels to spin and makes the surface  
under the tires slick, so there is even less traction.  
{ CAUTION:  
Snow can trap engine exhaust under the vehicle.  
This may cause exhaust gases to get inside.  
Engine exhaust contains carbon monoxide (CO)  
which cannot be seen or smelled. It can cause  
unconsciousness and even death.  
Try not to break the fragile traction. If you accelerate too  
fast, the drive wheels will spin and polish the surface  
under the tires even more.  
The Antilock Brake System (ABS) on page 4-5 improves  
vehicle stability during hard stops on a slippery roads, but  
apply the brakes sooner than when on dry pavement.  
If the vehicle is stuck in the snow:  
Clear away snow from around the base of  
your vehicle, especially any that is blocking the  
exhaust pipe and/or the fuel operated heater  
exhaust system, if equipped. If the vehicle has  
a diesel engine and a fuel operated heater, see  
“Fuel Operated Heater (FOH)” in the diesel  
Allow greater following distance on any slippery road  
and watch for slippery spots. Icy patches can occur on  
otherwise clear roads in shaded areas. The surface  
of a curve or an overpass can remain icy when the  
surrounding roads are clear. Avoid sudden steering  
maneuvers and braking while on ice.  
engine supplement.  
CAUTION: (Continued)  
Turn off cruise control, if equipped, on slippery surfaces.  
4-16  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Run the engine for short periods only as needed to  
keep warm, but be careful.  
CAUTION: (Continued)  
To save fuel, run the engine for only short periods as  
needed to warm the vehicle and then shut the engine  
off and close the window most of the way to save heat.  
Repeat this until help arrives but only when you feel really  
uncomfortable from the cold. Moving about to keep warm  
also helps.  
Check again from time to time to be sure  
snow does not collect there.  
Open a window about two inches (5 cm) on  
the side of the vehicle that is away from the  
wind to bring in fresh air.  
If it takes some time for help to arrive, now and then  
when you run the engine, push the accelerator pedal  
slightly so the engine runs faster than the idle speed.  
This keeps the battery charged to restart the vehicle and  
to signal for help with the headlamps. Do this as little as  
possible to save fuel.  
Fully open the air outlets on or under the  
instrument panel.  
Adjust the Climate Control system to a setting  
that circulates the air inside the vehicle and  
set the fan speed to the highest setting.  
See Climate Control System in the Index.  
For more information about carbon monoxide, see  
Engine Exhaust on page 2-31.  
Snow can trap exhaust gases under your vehicle.  
This can cause deadly CO (carbon monoxide) gas  
to get inside. CO could overcome you and kill you.  
You cannot see it or smell it, so you might not  
know it is in your vehicle. Clear away snow from  
around the base of your vehicle, especially any  
that is blocking the exhaust.

If Your Vehicle is Stuck in Sand,  
Mud, Ice, or Snow  
Rocking Your Vehicle to Get It Out  
Turn the steering wheel left and right to clear the area  
around the front wheels. Turn off any traction or stability  
system. Shift back and forth between R (Reverse) and a  
forward gear, spinning the wheels as little as possible.  
To prevent transmission wear, wait until the wheels stop  
spinning before shifting gears. Release the accelerator  
pedal while shifting, and press lightly on the accelerator  
pedal when the transmission is in gear. Slowly spinning  
the wheels in the forward and reverse directions causes a  
rocking motion that could free the vehicle. If that does not  
get the vehicle out after a few tries, it might need to be  
towed out. If the vehicle does need to be towed out, see  
Towing Your Vehicle on page 4-24.  
Slowly and cautiously spin the wheels to free the  
vehicle when stuck in sand, mud, ice, or snow.  
If the vehicle has a traction system, it can often help  
to free a stuck vehicle. Refer to the vehicle’s traction  
system in the Index. If stuck too severely for the traction  
system to free the vehicle, turn the traction system off  
and use the rocking method.  
{ CAUTION:  
If you let your vehicle’s tires spin at high speed,  
they can explode, and you or others could be  
injured. The vehicle can overheat, causing an  
engine compartment fire or other damage. Spin the  
wheels as little as possible and avoid going above  
35 mph (55 km/h) as shown on the speedometer.

Tire and Loading Information Label  
Loading the Vehicle  
It is very important to know how much weight  
your vehicle can carry. This weight is called the  
vehicle capacity weight and includes the weight of  
all occupants, cargo, and all nonfactory-installed  
options. Two labels on your vehicle show how  
much weight it was designed to carry, the  
Tire and Loading Information label and the  
Certification/Tire label.  
{ CAUTION:  
Do not load the vehicle any heavier than  
the Gross Vehicle Weight Rating (GVWR), or  
either the maximum front or rear Gross Axle  
Weight Rating (GAWR). If you do, parts on the  
vehicle can break, and it can change the way  
your vehicle handles. These could cause you  
to lose control and crash. Also, overloading  
can shorten the life of the vehicle.  
Label Example  
A vehicle specific Tire and Loading Information  
label is attached to the center pillar (B-pillar).  
With the driver’s door open, you will find the  
label attached below the door lock post (striker).  
The tire and loading information label shows  
the number of occupant seating positions (A),  
and the maximum vehicle capacity weight (B)  
in kilograms and pounds.  
The Tire and Loading Information label also shows  
the size of the original equipment tires (C) and  
the recommended cold tire inflation pressures (D).

passengers in your vehicle, the amount of  
available cargo and luggage load capacity  
is 650 lbs (1400 750 (5 x 150) = 650 lbs).  
5. Determine the combined weight of luggage  
and cargo being loaded on the vehicle.  
That weight may not safely exceed the  
available cargo and luggage load capacity  
calculated in Step 4.  
Steps for Determining Correct Load Limit  
1. Locate the statement “The combined weight  
of occupants and cargo should never exceed  
XXX kg or XXX lbs” on your vehicle’s placard.  
6. If your vehicle will be towing a trailer, the load  
from your trailer will be transferred to your  
vehicle. Consult this manual to determine how  
this reduces the available cargo and luggage  
load capacity of your vehicle. See Towing a  
Trailer on page 4-27 for important information  
on towing a trailer, towing safety rules and  
trailering tips.  
2. Determine the combined weight of the driver  
and passengers that will be riding in your  
vehicle.  
3. Subtract the combined weight of the driver  
and passengers from XXX kg or XXX lbs.

{ CAUTION:  
Things you put inside your vehicle can strike  
and injure people in a sudden stop or turn, or  
in a crash.  
Put things in the cargo area of your  
vehicle. Try to spread the weight evenly.  
Never stack heavier things, like  
suitcases, inside the vehicle so that some  
of them are above the tops of the seats.  
Do not leave an unsecured child restraint  
in your vehicle.  
Never exceed the GVWR for your vehicle, or the  
GAWR for either the front or rear axle.  
And, if you do have a heavy load, you should  
spread it out.  
When you carry something inside the  
vehicle, secure it whenever you can.  
Do not leave a seat folded down unless  
you need to.

Here are some important things to consider before  
recreational vehicle towing:  
Towing  
What is the towing capacity of the towing vehicle?  
Be sure to read the tow vehicle manufacturer’s  
recommendations.  
Towing Your Vehicle  
To avoid damage, the disabled vehicle should be towed  
with all four wheels off the ground. Consult your dealer/  
retailer or a professional towing service if the disabled  
vehicle must be towed. See Roadside Assistance  
Program on page 7-8.  
What is the distance that will be travelled? Some  
vehicles have restrictions on how far and how  
long they can tow.  
Is the proper towing equipment going to be used?  
See your dealer/retailer or trailering professional  
for additional advice and equipment  
recommendations.  
To tow the vehicle behind another vehicle for  
recreational purposes, such as behind a motorhome,  
see “Recreational Vehicle Towing” following.  
Is the vehicle ready to be towed? Just as preparing  
the vehicle for a long trip, make sure the vehicle is  
prepared to be towed. See Before Leaving on a  
Long Trip on page 4-14.  
Recreational Vehicle Towing  
Recreational vehicle towing means towing the vehicle  
behind another vehicle – such as behind a motorhome.  
The two most common types of recreational vehicle  
towing are known as dinghy towing and dolly towing.  
Dinghy towing is towing the vehicle with all four wheels  
on the ground. Dolly towing is towing the vehicle with  
two wheels on the ground and two wheels up on a  
device known as a dolly.

Two-Wheel-Drive Vehicles  
Dinghy Towing  
Notice: If the vehicle is towed with all four wheels  
on the ground, the drivetrain components could  
be damaged. The repairs would not be covered by  
the vehicle warranty. Do not tow the vehicle with all  
four wheels on the ground.  
Two-wheel-drive vehicles should not be towed  
with all four wheels on the ground. Two-wheel-drive  
transmissions have no provisions for internal lubrication  
while being towed.  
All-Wheel-Drive Vehicles  
The vehicle was not designed to be towed with all four  
wheels on the ground. To properly tow these vehicles,  
they should be placed on a platform trailer with all  
four wheels off the ground.  
Notice: Towing an all-wheel-drive vehicle with all  
four wheels on the ground, or even with only two of  
its wheels on the ground, will damage drivetrain  
components. Do not tow an all-wheel-drive vehicle  
with any of its wheels on the ground.

Use the following procedure to tow the vehicle from  
the rear:  
Dolly Towing  
Rear Towing (Rear Wheels Off the Ground)  
Two-Wheel-Drive Vehicles  
1. Attach the dolly to the tow vehicle following the  
dolly manufacturer’s instructions.  
2. Drive the rear wheels onto the dolly.  
3. Firmly set the parking brake. See Parking Brake on  
page 2-28 for more information.  
4. Put the transmission in P (Park).  
5. Secure the vehicle to the dolly following the  
manufacturer’s instructions.  
6. Use an adequate clamping device designed for  
towing to ensure that the front wheels are locked  
into the straight position.  
7. Turn the ignition to LOCK/OFF.  
If the tow vehicle will not be started or driven for  
six weeks or more, remove the battery cable  
from the negative terminal (post) of the battery to  
prevent the battery from draining while towing.

Towing a Trailer  
If the vehicle has a diesel engine, see the DURAMAX®  
Diesel manual for more information.  
{ CAUTION:  
The driver can lose control when pulling a trailer if  
the correct equipment is not used or the vehicle is  
not driven properly. For example, if the trailer is too  
heavy, the brakes may not work well — or even at  
all. The driver and passengers could be seriously  
injured. The vehicle may also be damaged; the  
resulting repairs would not be covered by the  
vehicle warranty. Pull a trailer only if all the steps in  
this section have been followed. Ask your dealer/  
retailer for advice and information about towing a  
trailer with the vehicle.  
The vehicle was not designed to be towed with two  
wheels on the ground. To properly tow these vehicles,  
they should be placed on a platform trailer with all  
four wheels off the ground.  
Notice: Pulling a trailer improperly can damage the  
vehicle and result in costly repairs not covered  
by the vehicle warranty. To pull a trailer correctly,  
follow the advice in this section and see your  
dealer/retailer for important information about  
towing a trailer with the vehicle.  
Notice: Towing an all-wheel-drive vehicle with all  
four wheels on the ground, or even with only two of  
its wheels on the ground, will damage drivetrain  
components. Do not tow an all-wheel-drive vehicle  
with any of its wheels on the ground.  
To identify the trailering capacity of the vehicle, read the  
information in “Weight of the Trailer” that appears later in  
this section.

Trailering is different than just driving the vehicle by  
itself. Trailering means changes in handling, acceleration,  
braking, durability and fuel economy. Successful, safe  
trailering takes correct equipment, and it has to be used  
properly.  
Do not tow a trailer at all during the first 500 miles  
(800 km) the new vehicle is driven. The engine,  
axle or other parts could be damaged.  
Then, during the first 500 miles (800 km) that a  
trailer is towed, do not drive over 50 mph (80 km/h)  
and do not make starts at full throttle. This helps  
the engine and other parts of the vehicle wear in  
at the heavier loads.  
The following information has many time-tested,  
important trailering tips and safety rules. Many of  
these are important for your safety and that of your  
passengers. So please read this section carefully  
before pulling a trailer.  
Vehicles with an automatic transmissions can tow in  
D (Drive). Shift the transmission to a lower gear if  
the transmission shifts too often under heavy  
loads and/or hilly conditions.  
Pulling A Trailer  
Here are some important points:  
Three important considerations have to do with weight:  
The weight of the trailer  
There are many different laws, including speed limit  
restrictions, having to do with trailering. Make sure  
the rig will be legal, not only where you live but  
also where you will be driving. A good source for  
this information can be state or provincial police.  
The weight of the trailer tongue  
The weight on the vehicle’s tires  
Also see Tow/Haul later in this section for information  
about the Tow/Haul button and the Tow/Haul  
indicator light.  
Consider using a sway control. See “Hitches” later  
in this section.

Maximum trailer weight is calculated assuming only the  
driver is in the tow vehicle and it has all the required  
trailering equipment. The weight of additional optional  
equipment, passengers and cargo in the tow vehicle  
must be subtracted from the maximum trailer weight.  
Weight of the Trailer  
How heavy can a trailer safely be?  
It depends on how the rig is used. For example,  
speed, altitude, road grades, outside temperature and  
how much the vehicle is used to pull a trailer are all  
important. It can depend on any special equipment on  
the vehicle, and the amount of tongue weight the vehicle  
can carry. See “Weight of the Trailer Tongue” later in  
this section for more information.

vehicle can weigh, based upon the vehicle model  
and options.

Weight of the Trailer Tongue  
The tongue load (A) of any trailer is an important weight  
to measure because it affects the total gross weight of the  
vehicle. The Gross Vehicle Weight (GVW) includes the  
curb weight of the vehicle, any cargo carried in it, and the  
people who will be riding in the vehicle. If there are a lot of  
options, equipment, passengers or cargo in the vehicle,  
it will reduce the tongue weight the vehicle can carry,  
which will also reduce the trailer weight the vehicle can  
tow. If towing a trailer, the tongue load must be added to  
the GVW because the vehicle will be carrying that weight,  
too. See Loading the Vehicle on page 4-19 for more  
information about the vehicle’s maximum load capacity.  
The trailer tongue weight (A) should be 10 percent to  
15 percent of the total loaded trailer weight (B), up to a  
maximum of 400 lbs (181 kg) with a weight carrying hitch.  
The trailer tongue weight (A) should be 10 percent to  
15 percent of the total loaded trailer weight (B), up to  
a maximum of 1,000 lbs (454 kg) with a weight  
distributing hitch.

Do not exceed the maximum allowable tongue weight  
for the vehicle. Choose the shortest hitch extension  
that will position the hitch ball closest to the vehicle.  
This will help reduce the effect of trailer tongue weight  
on the rear axle.  
Consider the following example:  
A vehicle model base weight is 5,500 lbs (2 495 kg);  
2,800 lbs (1 270 kg) at the front axle and 2,700 lbs  
(1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs  
(3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a  
GCWR (Gross Combination Weight Rating) of  
After loading the trailer, weigh the trailer and then the  
tongue, separately, to see if the weights are proper.  
If they are not, adjustments might be made by moving  
some items around in the trailer.  
14,000 lbs (6 350 kg). The trailer rating should be:  
Trailering may be limited by the vehicle’s ability to carry  
tongue weight. Tongue weight cannot cause the vehicle  
to exceed the GVWR (Gross Vehicle Weight Rating) or  
the RGAWR (Rear Gross Axle Weight Rating). The effect  
of additional weight may reduce the trailering capacity  
more than the total of the additional weight.  
Expect tongue weight to be at least 10 percent of trailer  
weight (850 lbs (386 kg)) and because the weight is  
applied well behind the rear axle, the effect on the rear  
axle is greater than just the weight itself, as much as  
1.5 times as much. The weight at the rear axle could be  
850 lbs (386 kg) X 1.5 = 1,275 lbs (578 kg). Since the  
rear axle already weighs 2,700 lbs (1 225 kg), adding  
1,275 lbs (578 kg) brings the total to 3,975 lbs (1 803 kg).  
This is very close to, but within the limit for RGAWR  
as well. The vehicle is set to trailer up to 8,500 lbs  
(3 856 kg).

If the vehicle has many options and there is a front  
seat passenger and two rear seat passengers with some  
luggage and gear in the vehicle as well. 300 lbs (136 kg)  
could be added to the front axle weight and 400 lbs  
(181 kg) to the rear axle weight. The vehicle now weighs:  
The effect of tongue weight is about 1.5 times the actual  
weight. Dividing the 900 lbs (408 kg) by 1.5 leaves only  
600 lbs (272 kg) of tongue weight that can be handled.  
Since tongue weight is usually at least 10 percent of total  
loaded trailer weight, expect that the largest trailer the  
vehicle can properly handle is 6,000 lbs (2 721 kg).  
It is important that the vehicle does not exceed any of  
its ratings — GCWR, GVWR, RGAWR, Maximum Trailer  
Rating or Tongue Weight. The only way to be sure it  
is not exceeding any of these ratings is to weigh  
the vehicle and trailer.  
Total Weight on the Vehicle’s Tires  
Be sure the vehicle’s tires are inflated to the upper  
limit for cold tires. These numbers can be found on the  
Certification label at the rear edge of the driver’s door or  
see Loading the Vehicle on page 4-19. Make sure not  
to go over the GVW limit for the vehicle, or the GAWR,  
including the weight of the trailer tongue. If using a weight  
distributing hitch, make sure not to go over the rear axle  
limit before applying the weight distribution spring bars.  
Weight is still below 7,200 lbs (3 266 kg) and you  
might think 700 additional pounds (318 kg) should be  
subtracted from the trailering capacity to stay within  
GCWR limits. The maximum trailer would only be  
7,800 lbs (3 538 kg). You may go further and think the  
tongue weight should be limited to less than 1,000 lbs  
(454 kg) to avoid exceeding GVWR. But the effect on  
the rear axle must still be considered. Because the rear  
axle now weighs 3,100 lbs (1 406 kg), 900 lbs (408 kg)  
can be put on the rear axle without exceeding RGAWR.

When using a weight-distributing hitch, the hitch must  
be adjusted so the distance (A) remains the same both  
before and after coupling the trailer to the tow vehicle.  
Hitches  
It is important to have the correct hitch equipment.  
Crosswinds, large trucks going by and rough roads are  
a few reasons why the right hitch is needed.  
If a step-bumper hitch will be used, the bumper could be  
damaged in sharp turns. Make sure there is ample room  
when turning to avoid contact between the trailer and the  
bumper.  
Weight-Distributing Hitches and Weight  
Carrying Hitches  
If the loaded trailer being pulled will weigh more than  
5,000 lbs (2 270 kg), be sure to use a properly mounted  
weight-distributing hitch and sway control of the proper  
size. This equipment is very important for proper vehicle  
loading and good handling when driving. Always use a  
sway control if the trailer will weigh more than these  
limits. Ask a hitch dealer about sway controls.  
Will any holes need to be made in the body of the  
vehicle when a trailer hitch is installed?  
If using the wiring provided with the factory-installed  
trailering package, no holes need to be made in  
the body of the vehicle. However, if an aftermarket hitch  
is installed, holes may need to be made in the body.  
If holes are made in the body, then be sure to seal the  
holes later when the hitch is removed. If the holes are not  
sealed, deadly carbon monoxide (CO) from the engine’s  
exhaust can get into the vehicle as well as dirt and water.  
See “Carbon Monoxide” under Engine Exhaust on  
page 2-31.

Tow/Haul is a feature that assists when pulling a heavy  
trailer or a large or heavy load. See Tow/Haul Mode  
on page 2-27 for more information.  
Safety Chains  
Always attach chains between the vehicle and the  
trailer. Cross the safety chains under the tongue of the  
trailer to help prevent the tongue from contacting the road  
if it becomes separated from the hitch. Always leave just  
enough slack so the rig can turn. Never allow safety  
chains to drag on the ground.  
Tow/Haul is designed to be most effective when the  
vehicle and trailer combined weight is at least 75 percent  
of the vehicle’s Gross Combined Weight Rating (GCWR).  
See “Weight of the Trailer” later in the section. Tow/Haul  
is most useful under the following driving conditions:  
Tow/Haul Mode  
When pulling a heavy trailer or a large or heavy load  
through rolling terrain.  
Pressing this button at  
the end of the shift lever  
turns on and off the  
tow/haul mode.  
When pulling a heavy trailer or a large or heavy load  
in stop and go traffic.  
When pulling a heavy trailer or a large or heavy load  
in busy parking lots where improved low speed  
control of the vehicle is desired.  
Operating the vehicle in Tow/Haul when lightly loaded  
or with no trailer at all will not cause damage. However,  
there is no benefit to the selection of Tow/Haul when  
the vehicle is unloaded. Such a selection when unloaded  
may result in unpleasant engine and transmission  
driving characteristics and reduced fuel economy.  
Tow/Haul is recommended only when pulling a heavy  
trailer or a large or heavy load.  
This indicator light on the  
instrument panel cluster  
comes on when the  
tow/haul mode is on.

Trailer Brakes  
CAUTION: (Continued)  
A loaded trailer that weighs more than 1,500 lbs  
(680 kg) needs to have its own brake system that is  
adequate for the weight of the trailer. Be sure to read  
and follow the instructions for the trailer brakes so  
they are installed, adjusted and maintained properly.  
Fully open the air outlets on or under the  
instrument panel.  
Adjust the Climate Control system to a setting  
that brings in only outside air and set the fan  
speed to the highest setting. See Climate  
Control System in the Index.  
Driving with a Trailer  
For more information about carbon monoxide, see  
Engine Exhaust on page 2-31  
{ CAUTION:  
When towing a trailer, exhaust gases may collect  
at the rear of the vehicle and enter if the liftgate,  
trunk/hatch, or rear-most window is open.  
Towing a trailer requires a certain amount of  
experience. Get to know the rig before setting out for the  
open road. Get acquainted with the feel of handling and  
braking with the added weight of the trailer. And always  
keep in mind that the vehicle you are driving is now  
longer and not as responsive as the vehicle is by itself.  
Engine exhaust contains carbon monoxide (CO)  
which cannot be seen or smelled. It can cause  
unconsciousness and even death.  
Before starting, check all trailer hitch parts and  
attachments, safety chains, electrical connectors,  
lamps, tires and mirror adjustments. If the trailer has  
electric brakes, start the vehicle and trailer moving and  
then apply the trailer brake controller by hand to be  
sure the brakes are working. This checks the electrical  
connection at the same time.  
To maximize safety when towing a trailer:  
Have the exhaust system inspected for leaks  
and make necessary repairs before starting  
a trip.  
Never drive with the liftgate, trunk/hatch, or  
rear-most window open.  
During the trip, check occasionally to be sure that the  
load is secure, and that the lamps and any trailer brakes  
are still working.  
CAUTION: (Continued)

Following Distance  
Making Turns  
Stay at least twice as far behind the vehicle ahead as  
you would when driving the vehicle without a trailer.  
This can help to avoid situations that require heavy  
braking and sudden turns.  
Notice: Making very sharp turns while trailering  
could cause the trailer to come in contact with the  
vehicle. The vehicle could be damaged. Avoid  
making very sharp turns while trailering.  
When turning with a trailer, make wider turns than  
normal. Do this so the trailer will not strike soft  
shoulders, curbs, road signs, trees or other objects.  
Avoid jerky or sudden maneuvers. Signal well in  
advance.  
Passing  
More passing distance is needed when towing a trailer.  
Because the rig is longer, it is necessary to go much  
farther beyond the passed vehicle before returning to  
the lane.  
Turn Signals When Towing a Trailer  
Backing Up  
The arrows on the instrument panel flash whenever  
signaling a turn or lane change. Properly hooked up, the  
trailer lamps also flash, telling other drivers the vehicle  
is turning, changing lanes or stopping.  
Hold the bottom of the steering wheel with one hand.  
Then, to move the trailer to the left, move that hand  
to the left. To move the trailer to the right, move your  
hand to the right. Always back up slowly and, if possible,  
have someone guide you.  
When towing a trailer, the arrows on the instrument  
panel flash for turns even if the bulbs on the trailer are  
burned out. For this reason you may think other drivers  
are seeing the signal when they are not. It is important to  
check occasionally to be sure the trailer bulbs are still  
working.

Driving On Grades  
Parking on Hills  
Reduce speed and shift to a lower gear before starting  
down a long or steep downgrade. If the transmission is  
not shifted down, the brakes might have to be used so  
much that they would get hot and no longer work well.  
{ CAUTION:  
Parking the vehicle on a hill with the trailer  
attached can be dangerous. If something goes  
wrong, the rig could start to move. People can be  
injured, and both the vehicle and the trailer can be  
damaged. When possible, always park the rig on a  
flat surface.  
The vehicle can tow in D (Drive). Shift the transmission  
to a lower gear if the transmission shifts too often  
under heavy loads and/or hilly conditions.  
When towing at high altitude on steep uphill grades,  
consider the following: Engine coolant will boil at a lower  
temperature than at normal altitudes. If the engine is  
turned off immediately after towing at high altitude on  
steep uphill grades, the vehicle may show signs similar  
to engine overheating. To avoid this, let the engine run  
while parked, preferably on level ground, with the  
automatic transmission in P (Park) for a few minutes  
before turning the engine off. If the overheat warning  
comes on, see Engine Overheating on page 5-32.  
If parking the rig on a hill:  
1. Press the brake pedal, but do not shift the  
transmission into P (Park) yet. Turn the wheels into  
the curb if facing downhill or into traffic if facing  
uphill.  
2. Have someone place chocks under the trailer  
wheels.  
3. When the wheel chocks are in place, release the  
brake pedal until the chocks absorb the load.  
4. Reapply the brake pedal. Then apply the parking  
brake and shift into P (Park).  
5. Release the brake pedal.

Trailer Wiring Harness  
1. Apply and hold the brake pedal while you:  
start the engine,  
The optional heavy-duty trailer wiring package includes  
a wiring harness, with a seven-pin connector at the rear  
of the vehicle and a four-wire harness assembly under  
the driver side of the instrument panel. The four-wire  
harness assembly comes without a connector.  
shift into a gear, and  
release the parking brake.  
If the vehicle does not have a trailer hitch, the  
seven-wire harness assembly with connector is taped  
together and located in a frame pocket at the driver  
side rear left corner of the frame.  
2. Let up on the brake pedal.  
3. Drive slowly until the trailer is clear of the chocks.  
4. Stop and have someone pick up and store the  
chocks.  
If the vehicle has a trailer hitch, the seven-wire harness  
assembly with connector is attached to a bracket on  
the hitch platform. In both cases, the seven-wire harness  
has a connector and includes a 30-amp feed wire.  
Maintenance When Trailer Towing  
The vehicle needs service more often when pulling  
a trailer. See this manual’s Maintenance Schedule or  
Index for more information. Things that are especially  
important in trailer operation are automatic transmission  
fluid, engine oil, axle lubricant, belts, cooling system  
and brake system. It is a good idea to inspect  
these before and during the trip.  
Check periodically to see that all hitch nuts and bolts  
are tight.

Gasoline  
Keep a record with all parts receipts and list the mileage  
and the date of any service work performed. See  
Maintenance Record on page 6-19.  
Use of the recommended fuel is an important part of the  
proper maintenance of this vehicle. To help keep the  
engine clean and maintain optimum vehicle performance,  
we recommend the use of gasoline advertised as TOP  
TIER Detergent Gasoline.  
Adding Equipment to the Outside of  
the Vehicle  
The 8th digit of the Vehicle Identification Number (VIN)  
shows the code letter or number that identifies the  
vehicle’s engine. The VIN is at the top left of the  
instrument panel. See Vehicle Identification Number  
(VIN) on page 5-106.  
Things added to the outside of the vehicle can affect the  
airflow around it. This can cause wind noise and can  
affect fuel economy and windshield washer performance.  
Check with your dealer/retailer before adding equipment  
to the outside of the vehicle.  
If the vehicle has the 5.3L V8 engine (VIN Code 4)  
and the N15 flexible fuel option, you can use either  
regular unleaded gasoline or ethanol fuel containing up  
to 85% ethanol (E85). See Fuel E85 (85% Ethanol) on  
page 5-8. For the 5.3L V8 engine (VIN Code 4) without  
the N15 option and all other gasoline engines, use only  
regular unleaded gasoline.

Gasoline Octane  
California Fuel  
Use regular unleaded gasoline with a posted octane  
rating of 87 or higher. If the octane rating is less than 87,  
you might notice an audible knocking noise when you  
drive, commonly referred to as spark knock. If this  
occurs, use a gasoline rated at 87 octane or higher as  
soon as possible. If you are using gasoline rated at  
87 octane or higher and you hear heavy knocking,  
the engine needs service.  
If the vehicle is certified to meet California Emissions  
Standards, it is designed to operate on fuels that meet  
California specifications. See the underhood emission  
control label. If this fuel is not available in states adopting  
California emissions standards, the vehicle will operate  
satisfactorily on fuels meeting federal specifications, but  
emission control system performance might be affected.  
The malfunction indicator lamp could turn on and the  
vehicle might fail a smog-check test. See Malfunction  
Indicator Lamp on page 3-34. If this occurs, return to your  
authorized dealer/retailer for diagnosis. If it is determined  
that the condition is caused by the type of fuel used,  
repairs might not be covered by the vehicle warranty.  
Gasoline Specifications  
At a minimum, gasoline should meet ASTM specification  
D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in  
Canada. Some gasolines contain an octane-enhancing  
additive called methylcyclopentadienyl manganese  
tricarbonyl (MMT). We recommend against the use of  
gasolines containing MMT. See Additives on page 5-7 for  
additional information.

Gasolines containing oxygenates, such as ethers and  
ethanol, and reformulated gasolines might be available in  
your area. We recommend that you use these gasolines,  
if they comply with the specifications described earlier.  
However, E85 (85% ethanol) and other fuels containing  
more than 10% ethanol must not be used in vehicles that  
were not designed for those fuels.  
Additives  
To provide cleaner air, all gasolines in the United States  
are now required to contain additives that help prevent  
engine and fuel system deposits from forming, allowing  
the emission control system to work properly. In most  
cases, you should not have to add anything to the fuel.  
However, some gasolines contain only the minimum  
amount of additive required to meet U.S. Environmental  
Protection Agency regulations. To help keep fuel injectors  
and intake valves clean, or if the vehicle experiences  
problems due to dirty injectors or valves, look for gasoline  
that is advertised as TOP TIER Detergent Gasoline.  
Notice: This vehicle was not designed for fuel  
that contains methanol. Do not use fuel containing  
methanol. It can corrode metal parts in the fuel  
system and also damage plastic and rubber parts.  
That damage would not be covered under the vehicle  
warranty.  
For customers who do not use TOP TIER Detergent  
Gasoline regularly, one bottle of GM Fuel System  
Treatment PLUS, added to the fuel tank at every engine  
oil change, can help clean deposits from fuel injectors  
and intake valves. GM Fuel System Treatment PLUS  
is the only gasoline additive recommended by General  
Motors.  
Some gasolines that are not reformulated for low  
emissions can contain an octane-enhancing additive  
called methylcyclopentadienyl manganese tricarbonyl  
(MMT); ask the attendant where you buy gasoline  
whether the fuel contains MMT. We recommend against  
the use of such gasolines. Fuels containing MMT can  
reduce the life of spark plugs and the performance  
of the emission control system could be affected. The  
malfunction indicator lamp might turn on. If this occurs,  
return to your dealer/retailer for service.  
Also, your dealer/retailer has additives that will help  
correct and prevent most deposit-related problems.

that can help you find E85 fuel. Those stations that do  
have E85 should have a label indicating ethanol  
content. Do not use the fuel if the ethanol content is  
greater than 85%.  
Fuel E85 (85% Ethanol)  
The 8th digit of the Vehicle Identification Number (VIN)  
shows the code letter or number that identifies the  
vehicle’s engine. The VIN is at the top left of the  
instrument panel. See Vehicle Identification Number  
(VIN) on page 5-106.  
At a minimum, E85 should meet ASTM  
Specification D 5798. By definition, this means  
that fuel labeled E85 will have an ethanol content  
between 70% and 85%. Filling the fuel tank with fuel  
mixtures that do not meet ASTM specifications can  
affect driveability and could cause the malfunction  
indicator lamp to come on.  
If the vehicle has the 5.3L V8 engine (VIN Code 4)  
and the N15 flexible fuel option, you can use either  
unleaded gasoline or ethanol fuel containing up  
to 85% ethanol (E85). See Fuel on page 5-5. For the  
5.3L V8 engine (VIN Code 4) without the N15 option  
and all other gasoline engines, use only the unleaded  
gasoline described under Gasoline Octane on page 5-6.  
To ensure quick starts in the wintertime, the E85 fuel  
must be formulated properly for your climate according  
to ASTM specification D 5798. If you have trouble  
starting on E85, it could be because the E85 fuel is not  
properly formulated for your climate. If this happens,  
switching to gasoline or adding gasoline to the fuel tank  
can improve starting. For good starting and heater  
efficiency below 32°F (0°C), the fuel mix in the fuel tank  
should contain no more than 70% ethanol. It is best  
not to alternate repeatedly between gasoline and E85.  
Only vehicles that have the 5.3L V8 engine (VIN Code 4)  
and the N15 flexible fuel option can use 85% ethanol  
fuel (E85). We encourage the use of E85 in vehicles  
that are designed to use it. The ethanol in E85 is a  
“renewable” fuel, meaning it is made from renewable  
sources such as corn and other crops.  
Many service stations will not have an 85% ethanol  
fuel (E85) pump available. The U. S. Department  
of Energy has an alternative fuels website  
(www.eere.energy.gov/afdc/infrastructure/locator.html)

If you do switch fuels, it is recommended that you  
add as much fuel as possible — do not add less than  
three gallons (11 L) when refueling. You should drive  
the vehicle immediately after refueling for at least  
seven miles (11 km) to allow the vehicle to adapt to  
the change in ethanol concentration.  
Notice: This vehicle was not designed for fuel that  
contains methanol. Do not use fuel containing  
methanol. It can corrode metal parts in the fuel  
system and also damage plastic and rubber parts.  
That damage would not be covered under the vehicle  
warranty.  
E85 has less energy per gallon than gasoline, so you will  
need to refill the fuel tank more often when using E85  
than when you are using gasoline. See Filling the Tank  
on page 5-10.  
Fuels in Foreign Countries  
If you plan on driving in another country outside the  
United States or Canada, the proper fuel might be hard  
to find. Never use leaded gasoline or any other fuel  
not recommended in the previous text on fuel. Costly  
repairs caused by use of improper fuel would not  
be covered by the vehicle warranty.  
Notice: Some additives are not compatible with E85  
fuel and can harm the vehicle’s fuel system. Do not  
add anything to E85. Damage caused by additives  
would not be covered by the vehicle warranty.  
To check the fuel availability, ask an auto club, or  
contact a major oil company that does business in the  
country where you will be driving.

{ CAUTION:  
Fuel vapor burns violently and a fuel fire can  
cause bad injuries. To help avoid injuries to you  
and others, read and follow all the instructions on  
the pump island. Turn off the engine when you are  
refueling. Do not smoke if you are near fuel or  
refueling the vehicle. Do not use cellular phones.  
Keep sparks, flames, and smoking materials away  
from fuel. Do not leave the fuel pump unattended  
when refueling the vehicle. This is against the law  
in some places. Do not re-enter the vehicle while  
pumping fuel. Keep children away from the fuel  
pump; never let children pump fuel.  
If the vehicle has E85 fuel capability, the fuel cap will be  
yellow and state that E85 or gasoline can be used.  
See Fuel E85 (85% Ethanol) on page 5-8.  
To remove the fuel cap, turn it slowly counterclockwise.  
While refueling, hang the tethered fuel cap from the

{ CAUTION:  
{ CAUTION:  
Fuel can spray out on you if you open the fuel cap  
too quickly. If you spill fuel and then something  
ignites it, you could be badly burned. This spray  
can happen if the tank is nearly full, and is more  
likely in hot weather. Open the fuel cap slowly and  
wait for any hiss noise to stop. Then unscrew the  
cap all the way.  
If a fire starts while you are refueling, do not  
remove the nozzle. Shut off the flow of fuel by  
shutting off the pump or by notifying the station  
attendant. Leave the area immediately.  
Notice: If you need a new fuel cap, be sure to get  
the right type. Your dealer/retailer can get one  
for you. If you get the wrong type, it may not fit  
properly. This may cause the malfunction indicator  
lamp to light and may damage the fuel tank and  
emissions system. See Malfunction Indicator Lamp  
on page 3-34.  
Be careful not to spill fuel. Do not top off or overfill the  
tank and wait a few seconds after you have finished  
pumping before removing the nozzle. Clean fuel from  
painted surfaces as soon as possible. See Washing  
Your Vehicle on page 5-102.  
When replacing the fuel cap, turn it clockwise until it  
clicks. Make sure the cap is fully installed. The diagnostic  
system can determine if the fuel cap has been left off or  
improperly installed. This would allow fuel to evaporate  
into the atmosphere. See Malfunction Indicator Lamp on

Cold Temperature Operation  
Engine Oil Life System  
If in an area of extreme cold, where the temperature  
falls below 20°F (29°C), use either an SAE 5W-30  
synthetic oil or an SAE 0W-30 engine oil. Both provide  
easier cold starting for the engine at extremely low  
temperatures. Always use an oil that meets the required  
specification, GM6094M. See “What Kind of Engine  
Oil to Use” for more information.  
When to Change Engine Oil  
This vehicle has a computer system that indicates when  
to change the engine oil and filter. This is based on  
engine revolutions and engine temperature, and not on  
mileage. Based on driving conditions, the mileage at  
which an oil change is indicated can vary considerably.  
For the oil life system to work properly, the system must  
be reset every time the oil is changed.  
Engine Oil Additives / Engine Oil  
Flushes  
When the system has calculated that oil life has been  
diminished, it indicates that an oil change is necessary.  
A CHANGE ENGINE OIL SOON message comes on.  
See DIC Warnings and Messages on page 3-48. Change  
the oil as soon as possible within the next 600 miles  
(1 000 km). It is possible that, if driving under the best  
conditions, the oil life system might not indicate that an oil  
change is necessary for over a year. However, the engine  
oil and filter must be changed at least once a year and at  
this time the system must be reset. Your dealer/retailer  
has trained service people who will perform this work  
using genuine parts and reset the system. It is also  
important to check the oil regularly and keep it at the  
proper level.  
Do not add anything to the oil. The recommended  
oils with the starburst symbol that meet GM Standard  
GM6094M are all that is needed for good performance  
and engine protection.  
Engine oil system flushes are not recommended and  
could cause engine damage not covered by the vehicle  
warranty.  
If the system is ever reset accidentally, the oil must be  
changed at 3,000 miles (5 000 km) since the last oil  
change. Remember to reset the oil life system whenever  
the oil is changed.

How to Reset the Engine Oil Life  
System  
What to Do with Used Oil  
Used engine oil contains certain elements that can be  
unhealthy for your skin and could even cause cancer.  
Do not let used oil stay on your skin for very long. Clean  
your skin and nails with soap and water, or a good  
hand cleaner. Wash or properly dispose of clothing or  
rags containing used engine oil. See the manufacturer’s  
warnings about the use and disposal of oil products.  
The Engine Oil Life System calculates when to change  
the engine oil and filter based on vehicle use. Whenever  
the oil is changed, reset the system so it can calculate  
when the next oil change is required. If a situation occurs  
where the oil is changed prior to a CHANGE ENGINE OIL  
SOON message being turned on, reset the system.  
Used oil can be a threat to the environment. If you  
change your own oil, be sure to drain all the oil from the  
filter before disposal. Never dispose of oil by putting it in  
the trash, pouring it on the ground, into sewers, or into  
streams or bodies of water. Recycle it by taking it to a  
place that collects used oil.  
To reset the CHANGE ENGINE OIL SOON message:  
1. Turn the ignition key to ON/RUN with the engine off.  
2. Fully press and release the accelerator pedal  
slowly three times within five seconds.  
3. Turn the key to LOCK/OFF.  
If the message comes back on when the vehicle is  
started, the engine oil life system has not reset. Repeat  
the procedure. If it still does not reset, see your dealer/  
retailer for service.

When to Inspect the Engine Air  
Cleaner/Filter  
Engine Air Cleaner/Filter  
If your vehicle has the DURAMAX Diesel engine, see  
the DURAMAX Diesel manual for more information.  
Inspect the air cleaner/filter at the Maintenance II  
intervals and replace it at the first oil change after each  
50,000 mile (80 000 km) interval. See Scheduled  
Maintenance on page 6-4 for more information. If you are  
driving in dusty/dirty conditions, inspect the filter at each  
engine oil change.  
How to Inspect the Engine Air  
Cleaner/Filter  
To inspect the air cleaner/filter, remove the filter from  
the vehicle and lightly shake the filter to release  
loose dust and dirt. If the filter remains caked with dirt, a  
new filter is required. Never use compressed air to  
clean the filter.  
The engine air cleaner/filter is located near the center of  
the engine compartment. See Engine Compartment  
Overview on page 5-14 for more information on location.

Get the vehicle warmed up by driving about 15 miles  
(24 km) when outside temperatures are above 50°F  
(10°C). If it is colder than 50°F (10°C), drive the vehicle  
in D (DRIVE) until the engine temperature gage  
moves and then remains steady for 10 minutes.  
How to Check Automatic Transmission  
Fluid  
Because this operation can be a little difficult, you may  
choose to have this done at the dealer/retailer service  
department.  
A cold fluid check can be made after the vehicle has  
been sitting for eight hours or more with the engine off,  
but this is used only as a reference. Let the engine  
run at idle for five minutes if outside temperatures are  
50°F (10°C) or more. If it is colder than 50°F (10°C), you  
may have to idle the engine longer. Should the fluid  
level be low during this cold check, you must check the  
fluid hot before adding fluid. Checking the fluid hot  
will give you a more accurate reading of the fluid level.  
If you do it yourself, be sure to follow all the instructions  
here, or you could get a false reading on the dipstick.  
Notice: Too much or too little fluid can damage your  
transmission. Too much can mean that some of the  
fluid could come out and fall on hot engine parts or  
exhaust system parts, starting a fire. Too little fluid  
could cause the transmission to overheat. Be sure  
to get an accurate reading if you check your  
transmission fluid.  
Checking the Fluid Level  
Prepare your vehicle as follows:  
Wait at least 30 minutes before checking the  
transmission fluid level if you have been driving:  
1. Park your vehicle on a level place. Keep the engine  
running.  
When outside temperatures are above 90°F (32°C).  
At high speed for quite a while.  
2. With the parking brake applied, place the shift lever  
in P (PARK).  
In heavy traffic — especially in hot weather.  
While pulling a trailer.  
3. With your foot on the brake pedal, move the shift  
lever through each gear range, pausing for about  
three seconds in each range. Then, position  
the shift lever in P (PARK).  
To get the right reading, the fluid should be at normal  
operating temperature, which is 180°F to 200°F  
(82°C to 93°C).  
4. Let the engine run at idle for three minutes or more.

Then, without shutting off the engine, follow these steps:  
The transmission dipstick  
is located near the center  
of the engine compartment  
and will be labeled with  
the graphic shown.  
3. Check both sides of the dipstick, and read the lower  
level. The fluid level must be in the COLD area for  
a cold check or in the HOT or cross-hatched  
area for a hot check. Be sure to keep the dipstick  
pointed down to get an accurate reading.  
See Engine Compartment Overview on page 5-14 for  
more information on location.  
1. Flip the handle up and then pull out the dipstick  
and wipe it with a clean rag or paper towel.  
4. If the fluid level is in the acceptable range, push the  
dipstick back in all the way; then flip the handle  
down to lock the dipstick in place.  
2. Push it back in all the way, wait three seconds and  
then pull it back out again.

How to Add Automatic Transmission  
Fluid  
Cooling System  
If your vehicle has a diesel engine, see “Van Models”  
under “Cooling System” in the DURAMAX® Diesel  
Supplement.  
Refer to the Maintenance Schedule to determine what  
kind of transmission fluid to use. See Recommended  
Fluids and Lubricants on page 6-15.  
The Cooling System allows the engine to maintain the  
correct working temperature.  
Using a funnel, add fluid down the transmission dipstick  
tube only after checking the transmission fluid while it is  
hot. A cold check is used only as a reference. If the fluid  
level is low, add only enough of the proper fluid to bring  
the level up to the HOT area for a hot check. It does not  
take much fluid, generally less than one pint (0.5 L).  
Do not overfill.  
Notice: Use of the incorrect automatic transmission  
fluid may damage the vehicle, and the damages may  
not be covered by the vehicle’s warranty. Always  
use the automatic transmission fluid listed in  
After adding fluid, recheck the fluid level as described  
under “How to Check Automatic Transmission Fluid,”  
earlier in this section.  
When the correct fluid level is obtained, push the  
dipstick back in all the way; then flip the handle down  
to lock the dipstick in place.

Notice: Using coolant other than DEX-COOL may  
cause premature engine, heater core, radiator  
and fuel operated heater (FOH) corrosion. In  
addition, the engine coolant may require changing  
sooner, at 30,000 miles (50 000 km) or 24 months,  
whichever occurs first. Any repairs would not  
be covered by your warranty. Always use DEX-COOL  
(silicate-free) coolant in your vehicle.  
{ CAUTION:  
An electric engine cooling fan under the hood can  
start up even when the engine is not running and  
can cause injury. Keep hands, clothing, and tools  
away from any underhood electric fan.  
Engine Coolant  
The cooling system in the vehicle is filled with  
DEX-COOL® engine coolant. This coolant is designed  
to remain in the vehicle for five years or 150,000 miles  
(240 000 km), whichever occurs first.  
{ CAUTION:  
Heater, fuel operated heater (FOH), radiator  
hoses, and other engine parts, can be very hot.  
Do not touch them. If you do, you can be burned.  
The following explains the cooling system and how to  
check and add coolant when it is low. If there is a  
problem with engine overheating, see Engine  
Overheating on page 5-32.  
Do not run the engine if there is a leak. If you run  
the engine, it could lose all coolant. That could  
cause an engine fire, and you could be burned.  
Get any leak fixed before you drive the vehicle.

needs to be added. This mixture:  
What to Use  
Gives freezing protection down to 34°F (37°C),  
{ CAUTION:  
outside temperature.  
Gives boiling protection up to 265°F (129°C),

Adding only plain water to the cooling system can  
be dangerous. Plain water, or some other liquid  
such as alcohol, can boil before the proper coolant  
mixture will. The vehicle’s coolant warning system  
is set for the proper coolant mixture. With plain  
water or the wrong mixture, the engine could

Notice: If an improper coolant mixture is used,  
the engine could overheat and be badly damaged.  
The repair cost would not be covered by the vehicle  
warranty. Too much water in the mixture can  
freeze and crack the engine, radiator, heater core,  
and other parts.  
Checking Coolant  
The vehicle must be on a level surface when checking  
the coolant level.  
Check to see if coolant is visible in the coolant recovery  
tank. If the coolant inside the coolant recovery tank is  
boiling, do not do anything else until it cools down. If  
coolant is visible but the coolant level is not at or above  
the COLD FILL mark, add a 50/50 mixture of clean,  
drinkable water and DEX-COOL® coolant at the coolant  
recovery tank, but be sure the cooling system is cool  
before this is done.  
Notice: If extra inhibitors and/or additives are used  
in the vehicle’s cooling system, the vehicle could  
be damaged. Use only the proper mixture of  
the engine coolant listed in this manual for the  
cooling system. See Recommended Fluids and  
Lubricants on page 6-15 for more information.  
When the engine is cold, the coolant level should be at or  
above the COLD FILL mark. If it is not, there could be a  
leak in the cooling system.  
If the coolant is low, add the coolant or take the vehicle  
to a dealer/retailer for service.

Notice: This vehicle has a specific coolant fill  
procedure. Failure to follow this procedure could  
cause the engine to overheat and be severely  
damaged.  
If coolant is needed, add the proper DEX-COOL®  
coolant mixture at the coolant recovery tank.  
How to Add Coolant to the Recovery  
Tank for Gasoline Engines  
If your vehicle has a diesel engine, see “How to  
Add Coolant to the Coolant Recovery Tank” under  
“Van Models” in the Cooling System section of the  
DURAMAX® Diesel Supplement for the proper coolant  
fill procedure.  
How to Add Coolant to the Radiator  
If your vehicle has a diesel engine, see “How to  
Add Coolant to the Radiator” under “Van Models” in the  
Cooling System section of the DURAMAX® Diesel  
Supplement for the proper radiator fill procedure.  
{ CAUTION:  
You can be burned if you spill coolant on hot  
engine parts. Coolant contains ethylene glycol  
and it will burn if the engine parts are hot enough.  
Do not spill coolant on a hot engine.  
{ CAUTION:  
An electric engine cooling fan under the hood can  
start up even when the engine is not running and  
can cause injury. Keep hands, clothing, and tools  
away from any underhood electric fan.

{ CAUTION:  
Steam and scalding liquids from a hot cooling  
system can blow out and burn you badly. They are  
under pressure, and if you turn the surge tank  
pressure cap — even a little — they can come out  
at high speed. Never turn the cap when the  
cooling system, including the surge tank pressure  
cap, is hot. Wait for the cooling system and surge  
tank pressure cap to cool if you ever have to turn  
the pressure cap.  
If coolant is needed, add the proper mixture directly to  
the radiator, but be sure the cooling system is cool  
before this is done.  
1. You can remove the radiator pressure cap when  
the cooling system, including the radiator pressure  
cap and upper radiator hose, is no longer hot. Turn  
the pressure cap slowly counterclockwise until it  
first stops. Do not press down while turning the  
pressure cap.  
If you hear a hiss, wait for that to stop. A hiss  
means there is still some pressure left.  
2. Then keep turning the pressure cap, but now push  
down as you turn it. Remove the pressure cap.

3. Fill the radiator with the proper DEX-COOL®  
coolant mixture, up to the base of the filler  
neck. See Engine Coolant on page 5-25 for more  
information about the proper coolant mixture.  
4. Then fill the coolant recovery tank to the COLD  
FILL mark.  
5. Put the cap back on the coolant recovery tank, but  
leave the radiator pressure cap off.

7. By this time, the coolant level inside the radiator  
filler neck may be lower. If the level is lower, add  
more of the proper DEX-COOL® coolant mixture  
through the filler neck until the level reaches  
the base of the filler neck.  
8. Then replace the pressure cap. At any time during  
this procedure if coolant begins to flow out of the  
filler neck, reinstall the pressure cap.  
Notice: If the pressure cap is not tightly installed,  
coolant loss and possible engine damage may  
occur. Be sure the cap is properly and tightly  
secured.  
6. Start the engine and let it run until you can feel the  
upper radiator hose getting hot. Watch out for the  
engine cooling fan.

You may decide not to lift the hood when this warning  
appears, but instead get service help right away.  
See Roadside Assistance Program on page 7-8.  
Radiator Pressure Cap  
The radiator pressure cap is located near the center of  
the engine compartment. See Engine Compartment  
Overview on page 5-14 for more information on location.  
If you do decide to lift the hood, make sure the vehicle  
is parked on a level surface.  
Notice: If the pressure cap is not tightly installed,  
coolant loss and possible engine damage may occur.  
Be sure the cap is properly and tightly secured.  
Then check to see if the engine cooling fans are running.  
If the engine is overheating, both fans should be running.  
If they are not, do not continue to run the engine and  
have the vehicle serviced.  
Engine Overheating  
See if the engine cooling fan speed increases when idle  
speed is doubled by pushing the accelerator pedal down.  
If it does not, your vehicle needs service. Turn off the  
engine.  
If your vehicle has the DURAMAX Diesel engine, see  
the DURAMAX Diesel manual for more information.  
The vehicle has an indicator to warn of engine  
overheating.  
Notice: Engine damage from running the engine  
without coolant is not covered by the warranty.  
You will find an engine coolant temperature gage on  
your vehicle’s instrument panel. See Engine Coolant  
Temperature Gage on page 3-33 for more information.  
Notice: If the engine catches fire because of being  
driven with no coolant, your vehicle can be badly  
damaged. The costly repairs would not be covered

If Steam Is Coming From The Engine  
Compartment  
If No Steam Is Coming From The  
Engine Compartment  
If an engine overheat warning is displayed but no steam  
can be seen or heard, the problem may not be too  
serious. Sometimes the engine can get a little too hot  
when the vehicle:  
{ CAUTION:  
Steam from an overheated engine can burn you  
badly, even if you just open the hood. Stay away  
from the engine if you see or hear steam coming  
from it. Just turn it off and get everyone away from  
the vehicle until it cools down. Wait until there is  
no sign of steam or coolant before you open  
the hood.  
Climbs a long hill on a hot day.  
Stops after high-speed driving.  
Idles for long periods in traffic.  
Tows a trailer. See “Driving on Grades” under  
Towing a Trailer on page 4-27.  
If the overheat warning is displayed with no sign of  
steam:  
If you keep driving when your engine is overheated,  
the liquids in it can catch fire. You or others could  
be badly burned. Stop your engine if it overheats,  
and get out of the vehicle until the engine is cool.  
1. Turn the air off.  
2. Turn the heater on to the highest temperature and  
to the highest fan speed. Open the windows as  
necessary.  
3. In heavy traffic, let the engine idle in N (Neutral)  
while stopped. If it is safe to do so, pull off the  
road, shift to P (Park) or N (Neutral) and let  
the engine idle.  
5-33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the temperature overheat gage is no longer in the  
overheat zone or an overheat warning no longer  
displays, the vehicle can be driven. Continue to drive  
the vehicle slow for about 10 minutes. Keep a safe  
vehicle distance from the car in front of you. If the  
warning does not come back on, continue to drive  
normally.  
Engine Fan Noise  
Your vehicle has a clutched engine cooling fan. When the  
clutch is engaged, the fan spins faster to provide more air  
to cool the engine. In most everyday driving conditions,  
the fan is spinning slower and the clutch is not fully  
engaged. This improves fuel economy and reduces fan  
noise. Under heavy vehicle loading, trailer towing, and/or  
high outside temperatures, the fan speed increases as  
the clutch more fully engages, so you may hear an  
increase in fan noise. This is normal and should not be  
mistaken as the transmission slipping or making extra  
shifts. It is merely the cooling system functioning properly.  
The fan will slow down when additional cooling is not  
required and the clutch partially disengages.  
If the warning continues, pull over, stop, and park the  
vehicle right away.  
If there is still no sign of steam, push down the  
accelerator until the engine speed is about twice as  
fast as normal idle speed for at least three minutes while  
you are parked. If you still have the warning, turn off  
the engine until it cools down.  
You may decide not to lift the hood but to get service  
help right away.  
You may also hear this fan noise when you start the  
engine. It will go away as the fan clutch partially  
disengages.

How to Check Power Steering Fluid  
Power Steering Fluid  
To check the power steering fluid, do the following:  
The power steering fluid

cool down.  
reservoir is located in the  
engine compartment on the  
driver’s side of the vehicle.  
Overview on page 5-14 for  
reservoir location.  
2. Wipe the cap and the top of the reservoir clean.  
3. Unscrew the cap and wipe the dipstick with a  
clean rag.  
4. Replace the cap and completely tighten it.  
5. Then remove the cap again and look at the fluid  
level on the dipstick.  
The level should be at the COLD FILL mark. If necessary,  
add only enough fluid to bring the level up to the mark.  
When to Check Power Steering Fluid  
To prevent contamination of brake fluid, never check or  
fill the power steering reservoir with the brake master  
cylinder cover off.  
It is not necessary to regularly check power steering fluid  
unless you suspect there is a leak in the system or  
you hear an unusual noise. A fluid loss in this system  
could indicate a problem. Have the system inspected  
and repaired.  
What to Use  
To determine what kind of fluid to use, see  
Always use the proper fluid. Failure to use the proper  
fluid can cause leaks and damage hoses and seals.

Notice:  
Windshield Washer Fluid  
What to Use  
When using concentrated washer fluid, follow  
the manufacturer’s instructions for adding  
water.  
When you need windshield washer fluid, be sure to read  
the manufacturer’s instructions before use. If you will be  
operating your vehicle in an area where the temperature  
may fall below freezing, use a fluid that has sufficient  
protection against freezing.  
Do not mix water with ready-to-use washer fluid.  
Water can cause the solution to freeze and  
damage your washer fluid tank and other parts  
of the washer system. Also, water does not  
clean as well as washer fluid.  
Adding Washer Fluid  
Fill the washer fluid tank only three-quarters full  
when it is very cold. This allows for fluid  
expansion if freezing occurs, which could  
damage the tank if it is completely full.  
Open the cap with the  
washer symbol on it.  
Add washer fluid until the  
tank is full. See Engine  
page 5-14 for reservoir  
location.  
Do not use engine coolant (antifreeze) in your  
windshield washer. It can damage the vehicle’s  
windshield washer system and paint.

Do not top off the brake fluid. Adding fluid does not  
correct a leak. If fluid is added when the linings  
are worn, there will be too much fluid when new brake  
linings are installed. Add or remove brake fluid, as  
necessary, only when work is done on the brake  
hydraulic system.  
Brakes  
Brake Fluid  
The brake master cylinder  
reservoir is filled with DOT  
3 brake fluid. See Engine  
page 5-14 for the location  
of the reservoir.  
{ CAUTION:  
If too much brake fluid is added, it can spill on  
the engine and/or fuel operated heater parts, if  
equipped. If the vehicle has a diesel engine and a  
fuel operated heater, see “Fuel Operated Heater  
(FOH)” in the diesel engine supplement. The  
fluid will burn if the engine is hot enough. You or  
others could be burned, and the vehicle could be  
damaged. Add brake fluid only when work is done  
on the brake hydraulic system. See “Checking  
Brake Fluid” in this section.  
There are only two reasons why the brake fluid level in  
the reservoir might go down:  
The brake fluid level goes down because of normal  
brake lining wear. When new linings are installed,  
the fluid level goes back up.  
A fluid leak in the brake hydraulic system can also  
cause a low fluid level. Have the brake hydraulic  
system fixed, since a leak means that sooner  
or later the brakes will not work well.  
Refer to the Maintenance Schedule to determine when  
to check the brake fluid. See Scheduled Maintenance  
on page 6-4.

Checking Brake Fluid  
{ CAUTION:  
Check brake fluid by looking at the brake fluid reservoir.  
See Engine Compartment Overview on page 5-14.  
With the wrong kind of fluid in the brake hydraulic  
system, the brakes might not work well. This could  
cause a crash. Always use the proper brake fluid.  
The fluid level should be  
above MIN. If it is not,  
have the brake hydraulic  
system checked to  
see if there is a leak.  
Notice:  
Using the wrong fluid can badly damage brake  
hydraulic system parts. For example, just a few  
drops of mineral-based oil, such as engine oil, in  
the brake hydraulic system can damage brake  
hydraulic system parts so badly that they will  
have to be replaced. Do not let someone put in  
the wrong kind of fluid.  
If brake fluid is spilled on the vehicle’s painted  
surfaces, the paint finish can be damaged. Be  
careful not to spill brake fluid on the vehicle. If  
you do, wash it off immediately. See Washing  
Your Vehicle on page 5-102.  
After work is done on the brake hydraulic system,  
make sure the level is above the MIN but not over the  
MAX mark.  
What to Add  
Use only new DOT 3 brake fluid from a sealed container.  
Always clean the brake fluid reservoir cap and the area  
around the cap before removing it. This helps keep dirt  
from entering the reservoir.

Properly torqued wheel nuts are necessary to help  
prevent brake pulsation. When tires are rotated, inspect  
brake pads for wear and evenly tighten wheel nuts in  
the proper sequence to torque specifications in  
Brake Wear  
This vehicle has disc brakes. Disc brake pads have  
built-in wear indicators that make a high-pitched warning  
sound when the brake pads are worn and new pads  
are needed. The sound can come and go or be heard all  
the time the vehicle is moving, except when applying  
the brake pedal firmly.  
Brake linings should always be replaced as complete  
axle sets.  
Brake Pedal Travel  
See your dealer/retailer if the brake pedal does not  
return to normal height, or if there is a rapid increase in  
pedal travel. This could be a sign that brake service  
might be required.  
{ CAUTION:  
The brake wear warning sound means that soon  
the brakes will not work well. That could lead to an  
accident. When the brake wear warning sound is  
heard, have the vehicle serviced.  
Brake Adjustment  
Every brake stop, the brakes adjust for wear.  
Notice: Continuing to drive with worn-out brake  
pads could result in costly brake repair.  
Some driving conditions or climates can cause a brake  
squeal when the brakes are first applied or lightly applied.  
This does not mean something is wrong with the brakes.

Replacing Brake System Parts  
Vehicle Storage  
The braking system on a vehicle is complex. Its many  
parts have to be of top quality and work well together if  
the vehicle is to have really good braking. The vehicle  
was designed and tested with top-quality brake parts.  
When parts of the braking system are replaced — for  
example, when the brake linings wear down and new  
ones are installed — be sure to get new approved  
replacement parts. If this is not done, the brakes might  
not work properly. For example, if someone puts in  
brake linings that are wrong for the vehicle, the balance  
between the front and rear brakes can change — for the  
worse. The braking performance expected can change in  
many other ways if the wrong replacement brake parts  
are installed.  
{ CAUTION:  
Batteries have acid that can burn you and gas that  
can explode. You can be badly hurt if you are not  
careful. See Jump Starting on page 5-41 for tips  
on working around a battery without getting hurt.  
Infrequent Usage: If the vehicle is driven infrequently,  
remove the black, negative () cable from the battery.  
This helps keep the battery from running down.  
Extended Storage: For extended storage of the vehicle,  
remove the black, negative () cable from the battery or  
use a battery trickle charger. This helps maintain the  
charge of the battery over an extended period of time.  
Battery  
This vehicle has a maintenance free battery. When it is  
time for a new battery, see your dealer/retailer for  
one that has the replacement number shown on the  
original battery’s label. See Engine Compartment  
Overview on page 5-14 for battery location.  
Warning: Battery posts, terminals, and related  
accessories contain lead and lead compounds,  
chemicals known to the State of California to cause  
cancer and reproductive harm. Wash hands after  
handling.

Notice: Ignoring these steps could result in costly  
damage to the vehicle that would not be covered  
by the warranty.  
Jump Starting  
If the vehicle battery has run down, you may want to use  
another vehicle and some jumper cables to start your  
vehicle. Be sure to use the following steps to do it safely.  
Trying to start the vehicle by pushing or pulling it  
will not work, and it could damage the vehicle.  
1. Check the other vehicle. It must have a 12-volt  
battery with a negative ground system.  
{ CAUTION:  
Notice: If the other vehicle’s system is not a 12-volt  
system with a negative ground, both vehicles can  
be damaged. Only use vehicles with 12-volt systems  
with negative grounds to jump start your vehicle.  
Batteries can hurt you. They can be dangerous  
because:  
They contain acid that can burn you.  
They contain gas that can explode or ignite.  
They contain enough electricity to burn you.  
2. Get the vehicles close enough so the jumper cables  
can reach, but be sure the vehicles are not touching  
each other. If they are, it could cause a ground  
connection you do not want. You would not be able  
to start your vehicle, and the bad grounding  
could damage the electrical systems.  
If you do not follow these steps exactly, some or  
all of these things can hurt you.  
To avoid the possibility of the vehicles rolling, set  
the parking brake firmly on both vehicles involved  
in the jump start procedure. Put an automatic  
transmission in P (PARK) or a manual transmission  
in NEUTRAL before setting the parking brake.

Notice: If you leave the radio or other accessories  
on during the jump starting procedure, they could be  
damaged. The repairs would not be covered by the  
warranty. Always turn off the radio and other  
accessories when jump starting the vehicle.  
On V6 engines the remote negative () terminal is  
located on a tab attached to the engine accessory  
drive bracket and is marked GND (Ground).  
{ CAUTION:  
3. Turn off the ignition on both vehicles. Unplug  
unnecessary accessories plugged into the cigarette  
lighter or the accessory power outlet. Turn off  
the radio and all lamps that are not needed. This  
will avoid sparks and help save both batteries. And  
it could save the radio!  
Using a match near a battery can cause battery  
gas to explode. People have been hurt doing this,  
and some have been blinded. Use a flashlight if  
you need more light.  
4. Open the hoods and locate the positive (+) and  
Be sure the battery has enough water. You do not  
need to add water to the battery installed in your  
new vehicle. But if a battery has filler caps, be

Do not connect positive (+) to negative () or you will  
get a short that would damage the battery and maybe  
other parts too. And do not connect the negative ()  
cable to the negative () terminal on the dead battery  
because this can cause sparks.  
7. Do not let the other end touch metal. Connect it to  
the positive (+) terminal of the good battery. Use a

next step. The other end of the negative () cable  
does not go to the dead battery. It goes to a  
heavy, unpainted metal engine part or to a remote  
negative () terminal on the vehicle with the dead  
battery.

Tires  
CAUTION: (Continued)  
Your new vehicle comes with high-quality tires  
made by a leading tire manufacturer. If you ever  
have questions about your tire warranty and where  
to obtain service, see your vehicle Warranty  
booklet for details. For additional information refer  
to the tire manufacturer.  
Underinflated tires pose the same danger  
as overloaded tires. The resulting  
accident could cause serious injury.  
Check all tires frequently to maintain the  
recommended pressure. Tire pressure  
should be checked when your vehicle’s  
tires are cold. See Inflation - Tire  
Pressure on page 5-64.  
Overinflated tires are more likely to be  
cut, punctured, or broken by a sudden  
impact — such as when you hit a  
pothole. Keep tires at the recommended  
pressure.  
{ CAUTION:  
Poorly maintained and improperly used tires  
are dangerous.  
Overloading your vehicle’s tires can  
cause overheating as a result of too  
much flexing. You could have an air-out  
and a serious accident. See Loading the  
Vehicle on page 4-19.  
Worn, old tires can cause accidents. If  
the tire’s tread is badly worn, or if your  
vehicle’s tires have been damaged,  
replace them.

How to Check  
Dual Tire Operation  
Use a good quality pocket-type gage to check tire  
pressure. You cannot tell if your tires are properly  
inflated simply by looking at them. Radial tires  
may look properly inflated even when they are  
underinflated. Check the tire’s inflation pressure  
when the tires are cold. Cold means your vehicle  
has been sitting for at least three hours or driven  
no more than 1 mile (1.6 km).  
When the vehicle is new, or whenever a wheel, wheel bolt  
or wheel nut is replaced, check the wheel nut torque after  
100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km)  
of driving. For proper wheel nut tightening information,  
see “Removing the Flat Tire and Installing the Spare Tire”  
later in this section, under Changing a Flat Tire on  
page 5-82. Also see “Wheel Nut Torque” under  
Remove the valve cap from the tire valve stem.  
Press the tire gage firmly onto the valve to  
get a pressure measurement. If the cold tire  
inflation pressure matches the recommended  
pressure on the Tire and Loading Information  
label, no further adjustment is necessary. If the  
pressure is low, add air until you reach the  
recommended amount.  
The outer tire on a dual wheel setup generally wears  
faster than the inner tire. Your tires will wear more  
evenly and last longer if you rotate the tires periodically.  
See Tire Inspection and Rotation on page 5-71. Also  
see Scheduled Maintenance on page 6-4.  
{ CAUTION:  
If you overfill the tire, release air by pushing on  
the metal stem in the center of the tire valve.  
Recheck the tire pressure with the tire gage.  
If you operate your vehicle with a tire that is badly  
underinflated, the tire can overheat. An overheated  
tire can lose air suddenly or catch fire. You or  
others could be injured. Be sure all tires (including  
the spare) are properly inflated.  
Be sure to put the valve caps back on the valve  
stems. They help prevent leaks by keeping out dirt  
and moisture.  
See Tires on page 5-55 and Inflation - Tire Pressure on  
page 5-64 for more information on proper tire inflation.

Please note that the TPMS is not a substitute for proper  
tire maintenance, and it is the driver’s responsibility to  
maintain correct tire pressure, even if under-inflation has  
not reached the level to trigger illumination of the TPMS  
low tire pressure telltale.  
Tire Pressure Monitor System  
The Tire Pressure Monitor System (TPMS) uses radio  
and sensor technology to check tire pressure levels.  
The TPMS sensors monitor the air pressure in your  
vehicle’s tires and transmit tire pressure readings to a  
receiver located in the vehicle.  
Your vehicle has also been equipped with a TPMS  
malfunction indicator to indicate when the system is not  
operating properly. The TPMS malfunction indicator  
is combined with the low tire pressure telltale. When  
the system detects a malfunction, the telltale will flash  
for approximately one minute and then remain  
continuously illuminated. This sequence will continue  
upon subsequent vehicle start-ups as long as the  
malfunction exists.  
Each tire, including the spare (if provided), should be  
checked monthly when cold and inflated to the inflation  
pressure recommended by the vehicle manufacturer  
on the vehicle placard or tire inflation pressure label.  
(If your vehicle has tires of a different size than the  
size indicated on the vehicle placard or tire inflation  
pressure label, you should determine the proper  
tire inflation pressure for those tires.)  
When the malfunction indicator is illuminated, the system  
may not be able to detect or signal low tire pressure as  
intended. TPMS malfunctions may occur for a variety of  
reasons, including the installation of replacement or  
alternate tires or wheels on the vehicle that prevent the  
TPMS from functioning properly. Always check the TPMS  
malfunction telltale after replacing one or more tires or  
wheels on your vehicle to ensure that the replacement or  
alternate tires and wheels allow the TPMS to continue to  
function properly.  
As an added safety feature, your vehicle has been  
equipped with a tire pressure monitoring system (TPMS)  
that illuminates a low tire pressure telltale when one  
or more of your tires is significantly under-inflated.  
Accordingly, when the low tire pressure telltale  
illuminates, you should stop and check your tires  
as soon as possible, and inflate them to the proper  
pressure. Driving on a significantly under-inflated tire  
causes the tire to overheat and can lead to tire failure.  
Under-inflation also reduces fuel efficiency and tire tread  
life, and may affect the vehicle’s handling and stopping  
ability.

additional information.

The low tire pressure warning light may come on in cool  
weather when the vehicle is first started, and then  
turn off as you start to drive. This could be an early  
indicator that the air pressure in the tire(s) are getting  
low and need to be inflated to the proper pressure.  
TPMS Malfunction Light and Message  
The TPMS will not function properly if one or more of the  
TPMS sensors are missing or inoperable. When the  
system detects a malfunction, the low tire warning light  
flashes for about one minute and then stays on for the  
remainder of the ignition cycle. A DIC warning message  
is also displayed. The low tire warning light and DIC  
warning message come on at each ignition cycle until the  
problem is corrected. Some of the conditions that can  
cause the malfunction light and DIC message to come  
on are:  
A Tire and Loading Information label, attached to  
your vehicle, shows the size of your vehicle’s original  
equipment tires and the correct inflation pressure  
for your vehicle’s tires when they are cold. See Loading  
the Vehicle on page 4-19, for an example of the Tire  
and Loading Information label and its location on  
your vehicle. Also see Inflation - Tire Pressure on  
page 5-64.  
One of the road tires has been replaced with the  
spare tire. The spare tire does not have a TPMS  
sensor. The TPMS malfunction light and DIC  
message should go off once you re-install the  
road tire containing the TPMS sensor.  
Your vehicle’s TPMS can warn you about a low tire  
pressure condition but it does not replace normal  
tire maintenance. See Tire Inspection and Rotation on  
page 5-71 and Tires on page 5-55.  
The TPMS sensor matching process was started but  
not completed or not completed successfully after  
rotating the vehicle’s tires. The DIC message and  
TPMS malfunction light should go off once the TPMS  
sensor matching process is performed successfully.  
See “TPMS Sensor Matching Process” later in this  
section.  
Notice: Liquid tire sealants could damage the Tire  
Pressure Monitor System (TPMS) sensors. Sensor  
damage caused by using a tire sealant is not covered  
by your warranty. Do not use liquid tire sealants.

One or more TPMS sensors are missing or  
damaged. The DIC message and the TPMS  
malfunction light should go off when the TPMS  
sensors are installed and the sensor matching  
process is performed successfully. See your dealer/  
retailer for service.  
TPMS Sensor Matching Process  
Each TPMS sensor has a unique identification code. Any  
time you rotate your vehicle’s tires or replace one or more  
of the TPMS sensors, the identification codes will need to  
be matched to the new tire/wheel position. The sensors  
are matched to the tire/wheel positions in the following  
order: driver side front tire, passenger side front tire,  
passenger side rear tire, and driver side rear tire using  
a TPMS diagnostic tool. See your dealer/retailer for  
service.  
Replacement tires or wheels do not match your  
vehicle’s original equipment tires or wheels. Tires  
and wheels other than those recommended for your  
vehicle could prevent the TPMS from functioning  
properly. See Buying New Tires on page 5-74.  
The TPMS sensors can also be matched to each  
tire/wheel position by increasing or decreasing the tire’s  
air pressure. If increasing the tire’s air pressure, do  
not exceed the maximum inflation pressure indicated on  
the tire’s sidewall.  
Operating electronic devices or being near facilities  
using radio wave frequencies similar to the TPMS  
could cause the TPMS sensors to malfunction.  
If the TPMS is not functioning it cannot detect or signal a  
low tire condition. See your dealer/retailer for service if  
the TPMS malfunction light and DIC message comes on  
and stays on.  
To decrease air-pressure out of a tire you can use the  
pointed end of the valve cap, a pencil-style air pressure  
gage, or a key.

5. Remove the valve cap from the valve cap stem.  
Activate the TPMS sensor by increasing or  
decreasing the tire’s air pressure for five seconds,  
or until a horn chirp sounds. The horn chirp,  
which may take up to 30 seconds to sound,  
confirms that the sensor identification code has  
been matched to this tire and wheel position.  
The TPMS sensor matching process is outlined  
below:  
1. Set the parking brake.  
2. Turn the ignition switch to ON/RUN with the  
engine off.

screen.  
6. Proceed to the passenger side front tire, and repeat  
the procedure in Step 5.  
7. Proceed to the passenger side rear tire, and repeat  
the procedure in Step 5.  
8. Proceed to the driver side rear tire, and repeat the  
procedure in Step 5. The horn sounds two times to  
indicate the sensor identification code has been  
matched to the driver side rear tire, and that  
the TPMS sensor matching process is no longer  
active. The TIRE LEARNING ACTIVE message on  
the DIC display screen goes off.  
If your vehicle does not have RKE, press the Driver  
Information Center (DIC) vehicle information  
button until the PRESS V TO RELEARN TIRE  
POSITIONS message displays. The horn sounds

Tire Inspection and Rotation  
Inspect tires regularly for signs of wear or damage.  
Also inspect the spare tire. For more information  
on tire inspection, see When It Is Time for  
New Tires on page 5-73.  
Tires should be rotated every 5,000 to 8,000 miles  
(8 000 to 13 000 km). See Scheduled Maintenance  
on page 6-4.  
The purpose of a regular tire rotation is to achieve  
a uniform wear for all tires on the vehicle. This  
will ensure that the vehicle continues to perform  
most like it did when the tires were new.  
Single Rear Wheels  
If your vehicle has single rear wheels, always use  
the correct rotation pattern shown here when  
rotating the vehicle’s tires. Do not include the spare  
tire in the tire rotation.  
Any time you notice unusual wear, rotate the tires  
as soon as possible and check wheel alignment.  
Also check for damaged tires or wheels. See  
Wheel Replacement on page 5-78.  
5-71  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Dual Rear Wheels  
If the vehicle has dual rear wheels and the tread  
design for the front tires is the same as the  
rear tires, always use one of the correct rotation  
patterns shown here when rotating the tires.  
If the vehicle has dual rear wheels and the tread  
design for the front tires is different from the dual  
rear tires, always use the correct rotation pattern  
shown here when rotating the tires. The dual tires  
are rotated as a pair and the inside rear tires  
become the outside rear tires.  
When you install dual wheels, be sure that vent  
holes in the inner and outer wheels on each  
side are lined up.  
Also see Dual Tire Operation on page 5-65 for  
additional information.

Download from Www.Somanuals.com. All Manuals Search And Download.  
After the tires have been rotated, adjust the front  
and rear inflation pressures as shown on the Tire  
and Loading Information label. See Inflation - Tire  
Pressure on page 5-64 and Loading the Vehicle on  
page 4-19. Make certain that all wheel nuts are  
properly tightened. See “Wheel Nut Torque” under  
Make sure the spare tire is stored securely. Push,  
pull, and then try to rotate or turn the tire. If it  
moves, tighten the cable. See Storing a Flat or  
Spare Tire and Tools on page 5-97.  
When It Is Time for New Tires  
Various factors, such as maintenance, temperatures,  
driving speeds, vehicle loading, and road conditions,  
influence when you need new tires.  
{ CAUTION:  
One way to tell when it is  
time for new tires is to  
check the treadwear  
indicators, which appear  
when your tires have  
only 1/16 inch (1.6 mm) or  
less of tread remaining.  
Rust or dirt on a wheel, or on the parts  
to which it is fastened, can make wheel  
nuts become loose after time. The wheel  
could come off and cause an accident.  
When you change a wheel, remove any rust  
or dirt from places where the wheel attaches  
to the vehicle. In an emergency, you can use  
a cloth or a paper towel to do this; but be  
sure to use a scraper or wire brush later, if  
needed, to get all the rust or dirt off. See  
Changing a Flat Tire on page 5-82.  
Some commercial truck tires, including Goodyear  
LT225/75R16 G949 RSA and Goodyear LT225/75R16  
G933 RSD, may not have treadwear indicators. If the  
tires do not have treadwear indicators, replace the tires  
when the tread depth is down to 1/8 inch (3.2 mm) for the  
front tires, or 1/16 inch (1.6 mm) for the rear tires.  
If your vehicle has a Tire Pressure Monitor  
System (TPMS), reset the TPMS sensors after  
rotating the tires. See Tire Pressure Monitor  
Operation on page 5-67.

You need new tires if any of the following statements  
are true:  
Buying New Tires  
GM has developed and matched specific tires for your  
vehicle. The original equipment tires installed on your  
vehicle, when it was new, were designed to meet  
General Motors Tire Performance Criteria Specification  
(TPC spec) system rating. If you need replacement tires,  
GM strongly recommends that you get tires with the  
same TPC Spec rating. This way, your vehicle will  
continue to have tires that are designed to give the  
same performance and vehicle safety, during normal  
use, as the original tires.  
You can see the indicators at three or more places  
around the tire.  
You can see cord or fabric showing through the  
tire’s rubber.  
The tread or sidewall is cracked, cut, or snagged  
deep enough to show cord or fabric.  
The tire has a bump, bulge, or split.  
The tire has a puncture, cut, or other damage that  
cannot be repaired well because of the size or  
location of the damage.  
GM’s exclusive TPC Spec system considers over a  
dozen critical specifications that impact the overall  
performance of your vehicle, including brake system  
performance, ride and handling, traction control, and tire  
pressure monitoring performance. GM’s TPC Spec  
number is molded onto the tire’s sidewall near the tire  
size. If the tires have an all-season tread design, the TPC  
spec number will be followed by a MS, for mud and snow.  
See Tire Sidewall Labeling on page 5-56 for additional  
information.  
The rubber in tires degrades over time, even if they are  
not being used. This is also true for the spare tire, if  
your vehicle has one. Multiple conditions affect how fast  
this aging takes place, including temperatures, loading  
conditions, and inflation pressure maintenance. With  
proper care and maintenance tires will typically wear out  
before they degrade due to age. If you are unsure  
about the need to replace your tires as they get older,  
consult the tire manufacturer for more information.  
GM recommends replacing tires in sets of four (or six if  
your vehicle has dual rear wheels). This is because  
uniform tread depth on all tires will help keep your vehicle  
performing most like it did when the tires were new.  
Replacing less than a full set of tires can affect the  
braking and handling performance of your vehicle. See  
Tire Inspection and Rotation on page 5-71 for information  
on proper tire rotation.  
5-74

If you must replace your vehicle’s tires with those that  
do not have a TPC Spec number, make sure they  
are the same size, load range, speed rating, and  
construction type (radial and bias-belted tires) as  
your vehicle’s original tires.  
{ CAUTION:  
Mixing tires could cause you to lose control  
while driving. If you mix tires of different  
sizes, brands, or types (radial and bias-belted  
tires) the vehicle may not handle properly,  
and you could have a crash. Using tires of  
different sizes, brands, or types may also  
cause damage to your vehicle. Be sure to  
use the correct size, brand, and type of tires  
on your vehicle’s wheels.  
Vehicles that have a tire pressure monitoring system  
could give an inaccurate low-pressure warning if  
non-TPC Spec rated tires are installed on your vehicle.  
Non-TPC Spec rated tires may give a low-pressure  
warning that is higher or lower than the proper warning  
level you would get with TPC Spec rated tires. See  
Your vehicle’s original equipment tires are listed on the  
Tire and Loading Information label. See Loading the  
Vehicle on page 4-19, for more information about  
the Tire and Loading Information label and its location  
on your vehicle.  
{ CAUTION:  
If you use bias-ply tires on the vehicle, the  
wheel rim flanges could develop cracks after  
many miles of driving. A tire and/or wheel  
could fail suddenly, causing a crash. Use only  
radial-ply tires with the wheels on the vehicle.

Different Size Tires and Wheels  
{ CAUTION:  
If you add wheels or tires that are a different size than  
your original equipment wheels and tires, this could  
affect the way your vehicle performs, including its  
braking, ride and handling characteristics, stability, and  
resistance to rollover. Additionally, if your vehicle  
has electronic systems such as anti-lock brakes, rollover  
airbags, traction control, and electronic stability control,  
the performance of these systems can be affected.  
If you add different sized wheels, your vehicle may  
not provide an acceptable level of performance and  
safety if tires not recommended for those wheels  
are selected. You may increase the chance that you  
will crash and suffer serious injury. Only use GM  
specific wheel and tire systems developed for your  
vehicle, and have them properly installed by a GM  
certified technician.

Treadwear  
Uniform Tire Quality Grading  
The treadwear grade is a comparative rating based  
on the wear rate of the tire when tested under  
controlled conditions on a specified government  
test course. For example, a tire graded 150 would  
wear one and a half (1.5) times as well on the  
government course as a tire graded 100. The  
relative performance of tires depends upon the  
actual conditions of their use, however, and may  
depart significantly from the norm due to variations  
in driving habits, service practices, and differences  
in road characteristics and climate.  
Quality grades can be found where applicable on  
the tire sidewall between tread shoulder and  
maximum section width. For example:  
Treadwear 200 Traction AA  
Temperature A  
The following information relates to the system  
developed by the United States National Highway  
Traffic Safety Administration (NHTSA), which  
grades tires by treadwear, traction, and  
temperature performance. This applies only to  
vehicles sold in the United States. The grades are  
molded on the sidewalls of most passenger car  
tires. The Uniform Tire Quality Grading (UTQG)  
system does not apply to deep tread, winter-type  
snow tires, space-saver, or temporary use spare  
tires, tires with nominal rim diameters of  
Traction – AA, A, B, C  
The traction grades, from highest to lowest, are AA,  
A, B, and C. Those grades represent the tire’s  
ability to stop on wet pavement as measured under  
controlled conditions on specified government test  
surfaces of asphalt and concrete. A tire marked C  
may have poor traction performance.  
10 to 12 inches (25 to 30 cm), or to some  
limited-production tires.  
While the tires available on General Motors  
passenger cars and light trucks may vary with  
respect to these grades, they must also conform to  
federal safety requirements and additional General  
Motors Tire Performance Criteria (TPC) standards.  
5-77  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Temperature – A, B, C  
Wheel Alignment and Tire Balance  
The temperature grades are A (the highest), B,  
and C, representing the tire’s resistance to the  
generation of heat and its ability to dissipate heat  
when tested under controlled conditions on a  
specified indoor laboratory test wheel. Sustained  
high temperature can cause the material of the tire  
to degenerate and reduce tire life, and excessive  
temperature can lead to sudden tire failure. The  
grade C corresponds to a level of performance  
which all passenger car tires must meet under the  
Federal Motor Vehicle Safety Standard No. 109.  
Grades B and A represent higher levels of  
performance on the laboratory test wheel than  
the minimum required by law. It should be  
noted that the temperature grade for this tire is  
established for a tire that is properly inflated and  
not overloaded. Excessive speed, underinflation,  
or excessive loading, either separately or in  
combination, can cause heat buildup and possible  
tire failure.  
The tires and wheels on your vehicle were aligned and  
balanced carefully at the factory to give you the longest  
tire life and best overall performance. Adjustments to  
wheel alignment and tire balancing will not be necessary  
on a regular basis. However, if you notice unusual tire  
wear or your vehicle pulling to one side or the other, the  
alignment might need to be checked. If you notice your  
vehicle vibrating when driving on a smooth road, the tires  
and wheels might need to be rebalanced. See your  
dealer/retailer for proper diagnosis.  
Wheel Replacement  
Replace any wheel that is bent, cracked, or badly rusted  
or corroded. If wheel nuts keep coming loose, the wheel,  
wheel bolts and wheel nuts should be replaced. If the  
wheel leaks air, replace it (except some aluminum  
wheels, which can sometimes be repaired). See your  
dealer/retailer if any of these conditions exist.  
5-78  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Your dealer/retailer will know the kind of wheel you need.  
Notice: The wrong wheel can also cause problems  
with bearing life, brake cooling, speedometer or  
odometer calibration, headlamp aim, bumper height,  
vehicle ground clearance, and tire or tire chain  
clearance to the body and chassis.  
Each new wheel should have the same load-carrying  
capacity, diameter, width, offset and be mounted  
the same way as the one it replaces.  
If you need to replace any of the wheels, wheel bolts,  
wheel nuts or Tire Pressure Monitor System (TPMS)  
sensors, replace them only with new GM original  
equipment parts. This way, you will be sure to have  
the right wheel, wheel bolts, wheel nuts, and TPMS  
sensors for the vehicle.  
Whenever a wheel, wheel bolt or wheel nut is replaced  
on a dual wheel setup, check the wheel nut torque  
after 100, 1,000 and 6,000 miles (160, 1 600 and  
10 000 km) of driving. For proper torque, see “Wheel  
on page 5-114.  
See Changing a Flat Tire on page 5-82 for more  
information.  
{ CAUTION:  
Used Replacement Wheels  
Using the wrong replacement wheels, wheel bolts,  
or wheel nuts on your vehicle can be dangerous.  
It could affect the braking and handling of your  
vehicle, make your tires lose air and make you  
lose control. You could have a collision in which  
you or others could be injured. Always use the  
correct wheel, wheel bolts, and wheel nuts for  
replacement.  
{ CAUTION:  
Putting a used wheel on the vehicle is dangerous.  
You cannot know how it has been used or how far  
it has been driven. It could fail suddenly and  
cause a crash. If you have to replace a wheel, use  
a new GM original equipment wheel.

Tire Chains  
CAUTION: (Continued)  
To help avoid damage to your vehicle, drive  
slowly, readjust, or remove the device if it is  
contacting your vehicle, and do not spin the  
vehicle’s wheels.  
{ CAUTION:  
If your vehicle has dual wheels or P245/70R17 or  
LT245/75R16 size tires, do not use tire chains.  
They can damage your vehicle because there is not  
enough clearance. Tire chains used on a vehicle  
without the proper amount of clearance can cause  
damage to the brakes, suspension, or other vehicle  
parts. The area damaged by the tire chains could  
cause you to lose control of your vehicle and you or  
others may be injured in a crash.  
If you do find traction devices that will fit, install  
them on the rear tires.  
Notice: If your vehicle does not have dual  
wheels and has a tire size other than P245/70R17 or  
LT245/75R16, use tire chains only where legal and  
only when you must. Use chains that are the proper  
size for your tires. Install them on the tires of the  
rear axle. Do not use chains on the tires of the front  
axle. Tighten them as tightly as possible with the  
ends securely fastened. Drive slowly and follow  
the chain manufacturer’s instructions. If you can  
hear the chains contacting your vehicle, stop and  
retighten them. If the contact continues, slow down  
until it stops. Driving too fast or spinning the wheels  
with chains on will damage your vehicle.  
Use another type of traction device only if its  
manufacturer recommends it for use on your  
vehicle and tire size combination and road  
conditions. Follow that manufacturer’s instructions.

If a Tire Goes Flat  
{ CAUTION:  
It is unusual for a tire to blowout while you are driving,  
especially if you maintain your vehicle’s tires properly.  
If air goes out of a tire, it is much more likely to leak out  
slowly. But if you should ever have a blowout, here  
are a few tips about what to expect and what to do:  
Lifting a vehicle and getting under it to do  
maintenance or repairs is dangerous without the  
appropriate safety equipment and training. If a jack  
is provided with the vehicle, it is designed only for  
changing a flat tire. If it is used for anything else,  
you or others could be badly injured or killed if the  
vehicle slips off the jack. If a jack is provided with  
the vehicle, only use it for changing a flat tire.  
If a front tire fails, the flat tire creates a drag that pulls  
the vehicle toward that side. Take your foot off the  
accelerator pedal and grip the steering wheel firmly.  
Steer to maintain lane position, and then gently brake to  
a stop well out of the traffic lane.  
A rear blowout, particularly on a curve, acts much like  
a skid and may require the same correction you would  
use in a skid. In any rear blowout remove your foot from  
the accelerator pedal. Get the vehicle under control by  
steering the way you want the vehicle to go. It may be  
very bumpy and noisy, but you can still steer. Gently  
brake to a stop, well off the road if possible.  
If a tire goes flat, the next part shows how to use the  
jacking equipment to change a flat tire safely.

Changing a Flat Tire  
CAUTION: (Continued)  
If a tire goes flat, avoid further tire and wheel damage  
by driving slowly to a level place. Turn on the hazard  
warning flashers. See Hazard Warning Flashers  
on page 3-6.  
3. Turn off the engine and do not restart while  
the vehicle is raised.  
4. Do not allow passengers to remain in the  
vehicle.  
{ CAUTION:  
To be even more certain the vehicle will not move,  
you should put blocks at the front and rear of the  
tire farthest away from the one being changed.  
That would be the tire, on the other side, at the  
opposite end of the vehicle.  
Changing a tire can be dangerous. The vehicle  
can slip off the jack and roll over or fall on you or  
other people. You and they could be badly injured  
or even killed. Find a level place to change your  
tire. To help prevent the vehicle from moving:  
When the vehicle has a flat tire (B), use the following  
example as a guide to assist you in the placement  
of wheel blocks (A).  
1. Set the parking brake firmly.  
2. Put the shift lever in P (Park).

because of a loose-running wheel, it could be that  
all of the studs are damaged. To be sure, replace all  
studs on the wheel. If the stud holes in a wheel  
have become larger, the wheel could collapse in  
operation. Replace any wheel if its stud holes have  
become larger or distorted in any way. Inspect hubs  
and hub-piloted wheels for damage. Because of  
loose running wheels, piloting pad damage may  
occur and require replacement of the entire hub, for  
proper centering of the wheels. When replacing  
studs, hubs, wheel nuts or wheels, be sure to use  
GM original equipment parts.  
Wheel nuts that are not tight can work loose. If all

To release the spare tire from the secondary latch:  
Secondary Latch System  
Your vehicle has an underbody-mounted tire hoist  
assembly equipped with a secondary latch system. It is  
designed to stop the spare tire from suddenly falling off  
the vehicle if the cable holding the spare tire is damaged.  
For the secondary latch to work, the tire must be stowed  
with the valve stem pointing down.  
{ CAUTION:  
Someone standing too close during the procedure  
could be injured by the jack. If the spare tire does  
not slide off the jack completely, make sure no  
one is behind you or on either side of you as you

Spare Tire  
This vehicle, when new, may have had a fully-inflated  
spare tire. A spare tire may lose air over time, so check  
its inflation pressure regularly. See Inflation - Tire  
Pressure on page 5-64 and Loading the Vehicle on  
page 4-19 for information regarding proper tire inflation  
and loading the vehicle. For instruction on how to  
remove, install or store a spare tire, see Removing the  
After installing the spare tire on the vehicle, you should  
stop as soon as possible and make sure the spare is  
correctly inflated. The spare tire is made to perform well  
at speeds up to 70 mph (112 km/h) at the recommended  
inflation pressure, so you can finish your trip.  
Have the damaged or flat road tire repaired or replaced  
as soon as you can and installed back onto the vehicle.  
This way, a spare tire will be available in case you need  
it again. Do not mix tires and wheels of different sizes,  
because they will not fit. Keep the spare tire and its wheel  
together.  
6. Make sure the tire is stored securely. Push, pull (A),  
and then try to turn (B) the tire. If the tire moves,  
use the wheel wrench to tighten the cable.  
You will hear two clicks when the tire is up all  
the way.

surfaces for which they were not intended. Use glass  
cleaner only on glass. Remove any accidental over-spray  
from other surfaces immediately. To prevent over-spray,  
apply cleaner directly to the cleaning cloth.  
Appearance Care  
Interior Cleaning  
Notice: Using abrasive cleaners when cleaning  
glass surfaces on the vehicle, could scratch  
the glass and/or cause damage to the rear window  
defogger. When cleaning the glass on the vehicle,  
use only a soft cloth and glass cleaner.  
The vehicle’s interior will continue to look its best if it is  
cleaned often. Although not always visible, dust and dirt  
can accumulate on the upholstery. Dirt can damage  
carpet, fabric, leather, and plastic surfaces. Regular  
vacuuming is recommended to remove particles from the  
upholstery. It is important to keep the upholstery from  
becoming and remaining heavily soiled. Soils should be  
removed as quickly as possible. The vehicle’s interior  
may experience extremes of heat that could cause stains  
to set rapidly.  
Many cleaners contain solvents that may become  
concentrated in the vehicle’s breathing space. Before  
using cleaners, read and adhere to all safety instructions  
on the label. While cleaning the vehicle’s interior,  
maintain adequate ventilation by opening the vehicle’s  
doors and windows.  
Lighter colored interiors may require more frequent  
cleaning. Use care because newspapers and garments  
that transfer color to home furnishings may also  
transfer color to the vehicle’s interior.  
Dust may be removed from small buttons and knobs  
using a small brush with soft bristles.  
Products that remove odors from the vehicle’s upholstery  
and clean the vehicle’s glass can be obtained from your  
dealer/retailer.  
When cleaning the vehicle’s interior, only use cleaners  
specifically designed for the surfaces being cleaned.  
Permanent damage may result from using cleaners on

Do not clean the vehicle using:  
Fabric/Carpet  
A knife or any other sharp object to remove a soil  
from any interior surface.  
Use a vacuum cleaner with a soft brush attachment  
frequently to remove dust and loose dirt. A canister  
vacuum with a beater bar in the nozzle may only be used  
on floor carpet and carpeted floor mats. For any soil,  
always try to remove it first with plain water or club soda.  
Before cleaning, gently remove as much of the soil as  
possible using one of the following techniques:  
A stiff brush. It can cause damage to the vehicle’s  
interior surfaces.  
Heavy pressure or aggressive rubbing with a  
cleaning cloth. Use of heavy pressure can damage  
the interior and does not improve the effectiveness  
of soil removal.  
For liquids: gently blot the remaining soil with a paper  
towel. Allow the soil to absorb into the paper towel  
until no more can be removed.  
Laundry detergents or dishwashing soaps with  
degreasers can leave residue that streaks and  
attracts dirt. For liquid cleaners, about 20 drops per  
gallon (3.78 L) of water is a good guide. Use  
only mild, neutral-pH soaps.  
For solid dry soils: remove as much as possible and  
then vacuum.  
Too much cleaner that saturates the upholstery.  
Organic solvents such as naptha, alcohol, etc. that  
can damage the vehicle’s interior.

To clean:  
Instrument Panel, Vinyl, and Other  
Plastic Surfaces  
1. Saturate a lint-free, clean white cloth with water or  
club soda.  
A soft cloth dampened with water may be used to  
remove dust. If a more thorough cleaning is necessary,  
a clean soft cloth dampened with a mild soap solution  
can be used to gently remove dust and dirt. Never  
use spot lifters or removers on plastic surfaces.  
Many commercial cleaners and coatings that are  
sold to preserve and protect soft plastic surfaces may  
permanently change the appearance and feel of  
the interior and are not recommended. Do not use  
silicone or wax-based products, or those containing  
organic solvents to clean the vehicle’s interior because  
they can alter the appearance by increasing the  
gloss in a non-uniform manner.  
2. Wring the cloth to remove excess moisture.  
3. Start on the outside edge of the soil and gently rub  
toward the center. Continue cleaning, using a clean  
area of the cloth each time it becomes soiled.  
4. Continue to gently rub the soiled area until the  
cleaning cloth remains clean.  
5. If the soil is not completely removed, use a mild  
soap solution and repeat the cleaning process  
that was used with plain water.  
If any of the soil remains, a commercial fabric cleaner  
or spot lifter may be necessary. When a commercial  
upholstery cleaner or spot lifter is to be used, test a small  
hidden area for colorfastness first. If the locally cleaned  
area gives any impression that a ring formation may  
result, clean the entire surface.  
Some commercial products may increase gloss on the  
instrument panel. The increase in gloss may cause  
annoying reflections in the windshield and even make it  
difficult to see through the windshield under certain  
conditions.  
After the cleaning process has been completed, a paper  
towel can be used to blot excess moisture from the  
fabric or carpet.

Care of Safety Belts  
Washing Your Vehicle  
Keep belts clean and dry.  
The best way to preserve the vehicle’s finish is to keep  
it clean by washing it often.  
Notice: Certain cleaners contain chemicals that can  
damage the emblems or nameplates on the vehicle.  
Check the cleaning product label. If it states that  
it should not be used on plastic parts, do not use it  
on the vehicle or damage may occur and it would  
not be covered by the warranty.  
{ CAUTION:  
Do not bleach or dye safety belts. It may severely  
weaken them. In a crash, they might not be able  
to provide adequate protection. Clean safety belts  
only with mild soap and lukewarm water.  
Do not wash the vehicle in direct sunlight. Use a car  
washing soap. Do not use cleaning agents that are  
petroleum based or that contain acid or abrasives, as  
they can damage the paint, metal or plastic on the  
vehicle. Approved cleaning products can be obtained  
from your dealer/retailer. Follow all manufacturers’  
directions regarding correct product usage, necessary  
safety precautions and appropriate disposal of any  
vehicle care product.  
Weatherstrips  
Silicone grease on weatherstrips will make them last  
longer, seal better, and not stick or squeak. Apply  
silicone grease with a clean cloth. During very cold,  
damp weather frequent application may be required. See  
Rinse the vehicle well, before washing and after to  
remove all cleaning agents completely. If they are  
allowed to dry on the surface, they could stain.  
Dry the finish with a soft, clean chamois or an all-cotton  
towel to avoid surface scratches and water spotting.

High pressure car washes may cause water to enter the  
vehicle. Avoid using high pressure washes closer  
than 12 inches (30 cm) to the surface of the vehicle.  
Use of power washers exceeding 1,200 psi (8 274 kPa)  
can result in damage or removal of paint and decals.  
Notice: Machine compounding or aggressive  
polishing on a basecoat/clearcoat paint finish may  
damage it. Use only non-abrasive waxes and  
polishes that are made for a basecoat/clearcoat  
paint finish on the vehicle.  
Foreign materials such as calcium chloride and other  
salts, ice melting agents, road oil and tar, tree sap, bird  
droppings, chemicals from industrial chimneys, etc.,  
can damage the vehicle’s finish if they remain on painted  
surfaces. Wash the vehicle as soon as possible. If  
necessary, use non-abrasive cleaners that are marked  
safe for painted surfaces to remove foreign matter.  
Cleaning Exterior Lamps/Lenses  
Use only lukewarm or cold water, a soft cloth and a car  
washing soap to clean exterior lamps and lenses.  
Follow instructions under Washing Your Vehicle on  
page 5-102.  
Exterior painted surfaces are subject to aging, weather  
and chemical fallout that can take their toll over a period  
of years. To help keep the paint finish looking new, keep  
the vehicle garaged or covered whenever possible.  
Finish Care  
Occasional waxing or mild polishing of the vehicle by  
hand may be necessary to remove residue from the paint  
finish. Approved cleaning products can be obtained from  
your dealer/retailer.  
Protecting Exterior Bright Metal Parts  
Bright metal parts should be cleaned regularly to keep  
their luster. Washing with water is all that is usually  
needed. However, chrome polish may be used on  
chrome or stainless steel trim, if necessary.  
If the vehicle has a basecoat/clearcoat paint finish, the  
clearcoat gives more depth and gloss to the colored  
basecoat. Always use waxes and polishes that are  
non-abrasive and made for a basecoat/clearcoat  
paint finish.  
Use special care with aluminum trim. To avoid damaging  
protective trim, never use auto or chrome polish, steam or  
caustic soap to clean aluminum. A coating of wax, rubbed  
to high polish, is recommended for all bright metal parts.

Windshield and Wiper Blades  
Aluminum Wheels  
Clean the outside of the windshield with glass cleaner.  
Notice: Using strong soaps, chemicals, abrasive  
polishes, cleaners, brushes, or cleaners that contain  
acid on aluminum or chrome-plated wheels, could  
damage the surface of the wheel(s). The repairs  
would not be covered by the warranty. Use only  
approved cleaners on aluminum or chrome-plated  
wheels.  
Clean the rubber blades using a lint free cloth or paper  
towel soaked with windshield washer fluid or a mild  
detergent. Wash the windshield thoroughly when  
cleaning the blades. Bugs, road grime, sap, and a  
buildup of vehicle wash/wax treatments may cause wiper  
streaking. Replace the wiper blades if they are worn or  
damaged.  
Keep the wheels clean using a soft clean cloth with mild  
soap and water. Rinse with clean water. After rinsing  
thoroughly, dry with a soft clean towel. A wax may then  
be applied.  
Wipers can be damaged by:  
Extreme dusty conditions  
Sand and salt  
Notice: Using chrome polish on aluminum wheels  
could damage the wheels. The repairs would not  
be covered by the warranty. Use chrome polish on  
chrome wheels only.

The surface of these wheels is similar to the painted  
surface of the vehicle. Do not use strong soaps,  
chemicals, abrasive polishes, abrasive cleaners,  
cleaners with acid, or abrasive cleaning brushes on  
them because the surface could be damaged. Do not  
use chrome polish on aluminum wheels.  
Sheet Metal Damage  
If the vehicle is damaged and requires sheet metal  
repair or replacement, make sure the body repair shop  
applies anti-corrosion material to parts repaired or  
replaced to restore corrosion protection.  
Original manufacturer replacement parts will provide  
the corrosion protection while maintaining the vehicle  
warranty.  
Notice: Driving the vehicle through an automatic  
car wash that has silicone carbide tire cleaning  
brushes, could damage the aluminum or  
chrome-plated wheels. The repairs would not be  
covered by the warranty. Never drive a vehicle  
equipped with aluminum or chrome-plated wheels  
through an automatic car wash that uses silicone  
carbide tire cleaning brushes.  
Finish Damage  
Any stone chips, fractures or deep scratches in the  
finish should be repaired right away. Bare metal  
will corrode quickly and may develop into major repair  
expense.  
Tires  
Minor chips and scratches can be repaired with touch-up  
materials available from your dealer/retailer. Larger areas  
of finish damage can be corrected in your dealer’s/  
retailer’s body and paint shop.  
To clean the tires, use a stiff brush with tire cleaner.  
Notice: Using petroleum-based tire dressing  
products on the vehicle may damage the paint finish  
and/or tires. When applying a tire dressing, always  
wipe off any overspray from all painted surfaces  
on the vehicle.

Underbody Maintenance  
Vehicle Identification  
Chemicals used for ice and snow removal and dust  
control can collect on the underbody. If these are not  
removed, corrosion and rust can develop on the  
underbody parts such as fuel lines, frame, floor pan,  
and exhaust system even though they have corrosion  
protection.  
Vehicle Identification Number (VIN)  
At least every spring, flush these materials from the  
underbody with plain water. Clean any areas where mud  
and debris can collect. Dirt packed in close areas of the  
frame should be loosened before being flushed. Your  
dealer/retailer or an underbody car washing system can  
do this.  
This is the legal identifier for the vehicle. It appears on a  
plate in the front corner of the instrument panel, on  
the driver side. It can be seen through the windshield  
from outside the vehicle. The VIN also appears on  
the Certification/Tire and Service Parts labels and the  
certificates of title and registration.  
Chemical Paint Spotting  
Some weather and atmospheric conditions can create a  
chemical fallout. Airborne pollutants can fall upon and  
attack painted surfaces on the vehicle. This damage can  
take two forms: blotchy, ring-shaped discolorations,  
and small, irregular dark spots etched into the  
paint surface.  
Engine Identification  
The eighth character in the VIN is the engine code. This  
code helps identify the vehicle’s engine, specifications,  
and replacement parts. See “Engine Specifications”  
under Capacities and Specifications on page 5-114 for  
the vehicle’s engine code.  
Although no defect in the paint job causes this, we will  
repair, at no charge to the owner, the surfaces of  
new vehicles damaged by this fallout condition within  
12 months or 12,000 miles (20 000 km) of purchase,  
whichever occurs first.

Do not remove this label from the vehicle.  
Electrical System  
Windshield Wiper Fuses  
Add-On Electrical Equipment  
The windshield wiper motor is protected by a circuit  
breaker and a fuse. If the motor overheats due to heavy  
snow, etc., the wiper will stop until the motor cools.  
Although the circuit is protected from electrical overload,  
overload due to heavy snow, etc., may cause wiper  
linkage damage. Always clear ice and heavy snow from  
the windshield before using the windshield wipers. If the  
overload is caused by some electrical problem and not  
snow, etc., be sure to get it fixed.  
Notice: Do not add anything electrical to the  
vehicle unless you check with your dealer/retailer  
first. Some electrical equipment can damage  
the vehicle and the damage would not be covered  
by the vehicle’s warranty. Some add-on electrical  
equipment can keep other components from  
working as they should.

Fuses and Circuit Breakers  
The wiring circuits in the vehicle are protected from  
short circuits by a combination of fuses and circuit  
breakers. This greatly reduces the chance of fires  
caused by electrical problems.  
Look at the silver-colored band inside the fuse. If the  
band is broken or melted, replace the fuse. Be sure you  
replace a bad fuse with a new one of the identical  
size and rating.

Maintenance Requirements  
Maintenance Schedule  
Notice: Maintenance intervals, checks, inspections,  
replacement parts, and recommended fluids and  
lubricants as prescribed in this manual are necessary  
to keep this vehicle in good working condition.  
Any damage caused by failure to follow scheduled  
maintenance might not be covered by the vehicle  
warranty.  
Introduction  
This maintenance section applies to vehicles with a  
gasoline engine. For diesel engine vehicles, see  
the maintenance schedule section in the DURAMAX  
Diesel manual.  
Important: Keep engine oil at the proper level and  
change as recommended.  
Your Vehicle and the Environment  
Proper vehicle maintenance not only helps to keep  
the vehicle in good working condition, but also helps  
the environment. All recommended maintenance is  
important. Improper vehicle maintenance can even affect  
the quality of the air we breathe. Improper fluid levels or  
the wrong tire inflation can increase the level of emissions  
from the vehicle. To help protect the environment, and to  
keep the vehicle in good condition, be sure to maintain  
the vehicle properly.  
Have you purchased the GM Protection Plan? The Plan  
supplements the vehicle warranties. See the Warranty  
and Owner Assistance booklet or your dealer/retailer for  
details.

Using the Maintenance Schedule  
{ CAUTION:  
We want to help keep this vehicle in good working  
condition. But we do not know exactly how you will  
drive it. You might drive very short distances only a few  
times a week. Or you might drive long distances all  
the time in very hot, dusty weather. You might use the  
vehicle in making deliveries. Or you might drive it to  
work, to do errands, or in many other ways.  
Performing maintenance work on a vehicle can be  
dangerous. In trying to do some jobs, you can be  
seriously injured. Do your own maintenance work  
only if you have the required know-how and the  
proper tools and equipment for the job. If you have  
any doubt, see your dealer/retailer to have a  
qualified technician do the work. See Doing Your  
Own Service Work on page 5-4.  
Because of all the different ways people use their  
vehicles, maintenance needs vary. You might need more  
frequent checks and replacements. So please read  
the following and note how you drive. If you have any  
questions on how to keep the vehicle in good condition,  
see your dealer/retailer.  
Some maintenance services can be complex. So, unless  
you are technically qualified and have the necessary  
equipment, have your dealer/retailer do these jobs.  
This schedule is for vehicles that:  
carry passengers and cargo within recommended  
limits on the Tire and Loading Information label.  
See Loading the Vehicle on page 4-19.  
are driven on reasonable road surfaces within legal  
driving limits.  
When you go to your dealer/retailer for service, trained  
and supported service technicians will perform the  
work using genuine parts.  
To purchase service information, see Service  
use the recommended fuel. See Gasoline Octane  
on page 5-6.  
Owner Checks and Services on page 6-11 tells what  
should be checked, when to check it, and what can easily  
be done to help keep the vehicle in good condition.  
The services in Scheduled Maintenance on page 6-4  
should be performed when indicated. See Additional  
Footnotes (Gasoline Engine) on page 6-9 for further  
information.  
6-3

The proper replacement parts, fluids, and lubricants to  
on page 6-17. When the vehicle is serviced, make sure  
these are used. All parts should be replaced and all  
necessary repairs done before you or anyone else  
drives the vehicle. We recommend the use of genuine  
parts from your dealer/retailer.  
If the engine oil life system is ever reset accidentally,  
service the vehicle within 3,000 miles (5 000 km)  
since the last service. Remember to reset the oil life  
system whenever the oil is changed. See Engine Oil  
Life System on page 5-18 for information on the Engine  
Oil Life System and resetting the system.  
When the CHANGE ENGINE OIL SOON message  
appears, certain services, checks, and inspections are  
required. Required services are described in the  
following for “Maintenance I” and “Maintenance II.”  
Generally, it is recommended that the first service be  
Maintenance I, the second service be Maintenance II,  
and then alternate Maintenance I and Maintenance II  
thereafter. However, in some cases, Maintenance II  
may be required more often.  
Scheduled Maintenance  
This maintenance section applies to vehicles with a  
gasoline engine. For diesel engine vehicles, see  
the maintenance schedule section in the DURAMAX®  
Diesel manual.  
When the CHANGE ENGINE OIL SOON message  
displays, service is required for the vehicle. Have the  
vehicle serviced as soon as possible within the next  
600 miles (1 000 km). It is possible that, if driving under  
the best conditions, the engine oil life system may not  
indicate that vehicle service is necessary for over a year.  
However, the engine oil and filter must be changed at  
least once a year and at this time the system must be  
reset. Your dealer/retailer has trained service technicians  
who will perform this work using genuine parts and reset  
the system.  
Maintenance I — Use Maintenance I if the CHANGE  
ENGINE OIL SOON message displays within 10 months  
since the vehicle was purchased or Maintenance II  
was performed.  
Maintenance II — Use Maintenance II if the previous  
service performed was Maintenance I. Always use  
Maintenance II whenever the message displays  
10 months or more since the last service or if the  
message has not come on at all for one year.

recommended at least once a year.  
Maintenance Footnotes  
(Gasoline Engine)  
This maintenance section applies to vehicles with a  
gasoline engine. For diesel engine vehicles, see  
the maintenance schedule section in the DURAMAX®  
Diesel manual.  
(d) Inspect wiper blades for wear, cracking, or  
contamination. Clean the windshield and wiper blades,  
if contaminated. Replace wiper blades that are worn  
on page 5-54 and Windshield and Wiper Blades on  
page 5-104 for more information.  
The U.S. Environmental Protection Agency or the  
California Air Resources Board has determined that the  
failure to perform this maintenance item will not nullify  
the emission warranty or limit recall liability prior to the  
completion of the vehicle’s useful life. We, however,  
urge that all recommended maintenance services be  
performed at the indicated intervals and the maintenance  
be recorded.  
(e) Make sure the safety belt reminder light and safety  
belt assemblies are working properly. Look for any other  
loose or damaged safety belt system parts. If you see  
anything that might keep a safety belt system from doing  
its job, have it repaired. Have any torn or frayed safety  
belts replaced. Also see Checking the Restraint Systems  
on page 1-75.  
# Lubricate the front suspension, kingpin bushings,  
steering linkage, and rear driveline center splines.  
(a) Visually inspect brake lines and hoses for proper  
hook-up, binding, leaks, cracks, chafing, etc. Inspect  
disc brake pads for wear and rotors for surface  
condition. Inspect other brake parts, including calipers,  
parking brake, etc.  
(f) Lubricate all key lock cylinders, hood hinges, hood  
prop rod pivot, hood latch assembly, secondary latch,  
pivots, spring anchor, release pawl, rear compartment  
hinges, latches, locks, fuel door hinge, and any moving  
seat hardware. More frequent lubrication may be required  
when exposed to a corrosive environment. Applying  
silicone grease on weatherstrips with a clean cloth will  
make them last longer, seal better, and not stick or  
squeak.  
(b) Visually inspect front and rear suspension and  
steering system for damaged, loose, or missing parts,  
signs of wear, or lack of lubrication. Inspect power  
steering lines and hoses for proper hook-up, binding,  
leaks, cracks, chafing, etc.

STEP TWO: If after contacting a member of dealership  
management, it appears your concern cannot be  
resolved by the dealership without further help, in  
the U.S., call the Chevrolet Customer Assistance  
Center at 1-800-222-1020. In Canada, call General  
Motors of Canada Customer Communication Centre  
at 1-800-263-3777 (English), or 1-800-263-7854  
(French).  
Customer Assistance and  
Information  
Customer Satisfaction Procedure  
Your satisfaction and goodwill are important to your  
dealer and to Chevrolet. Normally, any concerns with the  
sales transaction or the operation of the vehicle will be  
resolved by the dealer’s sales or service departments.  
Sometimes, however, despite the best intentions of all  
concerned, misunderstandings can occur. If your concern  
has not been resolved to your satisfaction, the following  
steps should be taken:  
We encourage you to call the toll-free number in  
order to give your inquiry prompt attention. Have the  
following information available to give the Customer  
Assistance Representative:  
Vehicle Identification Number (VIN). This is  
available from the vehicle registration or title,  
or the plate at the top left of the instrument  
panel and visible through the windshield.  
STEP ONE: Discuss your concern with a member  
of dealership management. Normally, concerns can  
be quickly resolved at that level. If the matter has  
already been reviewed with the sales, service, or parts  
manager, contact the owner of the dealership or the  
general manager.  
Dealership name and location.  
Vehicle delivery date and present mileage.  
When contacting Chevrolet, remember that your  
concern will likely be resolved at a dealer’s facility.  
That is why we suggest following Step One first.

STEP THREE — U.S. Owners: Both General Motors  
and your dealer are committed to making sure you  
are completely satisfied with your new vehicle. However,  
if you continue to remain unsatisfied after following  
the procedure outlined in Steps One and Two, you can  
file with the Better Business Bureau (BBB) Auto Line  
Program to enforce your rights.  
You may contact the BBB Auto Line Program using the  
toll-free telephone number or write them at the following  
address:  
BBB Auto Line Program  
Council of Better Business Bureaus, Inc.  
4200 Wilson Boulevard  
Suite 800  
Arlington, VA 22203-1838  
The BBB Auto Line Program is an out of court program  
administered by the Council of Better Business Bureaus  
to settle automotive disputes regarding vehicle repairs or  
the interpretation of the New Vehicle Limited Warranty.  
Although you may be required to resort to this informal  
dispute resolution program prior to filing a court action,  
use of the program is free of charge and your case will  
generally be heard within 40 days. If you do not agree  
with the decision given in your case, you may reject it and  
proceed with any other venue for relief available to you.  
Telephone: 1-800-955-5100  
dr.bbb.org/goauto  
This program is available in all 50 states and the  
District of Columbia. Eligibility is limited by vehicle age,  
mileage, and other factors. General Motors reserves  
the right to change eligibility limitations and/or  
discontinue its participation in this program.

STEP THREE — Canadian Owners: In the event  
that you do not feel your concerns have been addressed  
after following the procedure outlined in Steps 1 and 2,  
General Motors of Canada Limited wants you to be  
aware of its participation in a no-charge Mediation/  
Arbitration Program. General Motors of Canada  
Limited has committed to binding arbitration of owner  
disputes involving factory-related vehicle service claims.  
The program provides for the review of the facts involved  
by an impartial third party arbiter, and may include an  
informal hearing before the arbiter. The program is  
designed so that the entire dispute settlement process,  
from the time you file your complaint to the final decision,  
should be completed in about 70 days. We believe our  
impartial program offers advantages over courts in most  
jurisdictions because it is informal, quick, and free of  
charge.  
For further information concerning eligibility in the  
Canadian Motor Vehicle Arbitration Plan (CAMVAP),  
call toll-free 1-800-207-0685, or call the General Motors  
Customer Communication Centre, 1-800-263-3777

If your vehicle cannot be scheduled into the service  
department immediately, keep driving it until it can be  
scheduled for service, unless, of course, the problem is  
safety-related. If it is, please call your dealership/retailer,  
let them know this, and ask for instructions.  
Trip Interruption Benefits and Assistance: Must  
be over 250 kilometres from where your trip was  
started to qualify. General Motors of Canada Limited  
requires pre-authorization, original detailed receipts,  
and a copy of the repair orders. Once authorization  
has been received, the Roadside Assistance advisor  
will help you make arrangements and explain how to  
receive payment.  
If the dealer/retailer requests you to bring the vehicle for  
service, you are urged to do so as early in the work  
day as possible to allow for the same day repair.  
Alternative Service: If assistance cannot be  
provided right away, the Roadside Assistance  
advisor may give you permission to get local  
emergency road service. You will receive payment,  
up to $100, after sending the original receipt to  
Roadside Assistance. Mechanical failures may be  
covered, however any cost for parts and labor for  
repairs not covered by the warranty are the owner  
responsibility.  
Courtesy Transportation  
To enhance your ownership experience, we and our  
participating dealers are proud to offer Courtesy  
Transportation, a customer support program for vehicles  
with the Bumper to Bumper (Base Warranty Coverage  
period in Canada) and extended powertrain, and  
hybrid specific warranty in both the U.S. and Canada.  
Several courtesy transportation options are available to  
assist in reducing your inconvenience when warranty  
repairs are required.  
Scheduling Service Appointments  
When your vehicle requires warranty service, contact  
your dealer/retailer and request an appointment.  
By scheduling a service appointment and advising your  
service consultant of your transportation needs, your  
dealer/retailer can help minimize your inconvenience.  
Courtesy Transportation is not a part of the New Vehicle  
Limited Warranty. A separate booklet entitled “Warranty  
and Owner Assistance Information” furnished with  
each new vehicle provides detailed warranty coverage  
information.

Courtesy Rental Vehicle  
Transportation Options  
Your dealer may arrange to provide you with a courtesy  
rental vehicle or reimburse you for a rental vehicle that  
you obtain if your vehicle is kept for an overnight warranty  
repair. Rental reimbursement will be limited and must be  
supported by original receipts. This requires that you  
sign and complete a rental agreement and meet state/  
provincial, local, and rental vehicle provider requirements.  
Requirements vary and may include minimum age  
requirements, insurance coverage, credit card, etc.  
You are responsible for fuel usage charges and may  
also be responsible for taxes, levies, usage fees,  
excessive mileage, or rental usage beyond the  
completion of the repair.  
Warranty service can generally be completed while you  
wait. However, if you are unable to wait, GM helps  
to minimize your inconvenience by providing several  
transportation options. Depending on the circumstances,  
your dealer can offer you one of the following:  
Shuttle Service  
Shuttle service is the preferred means of offering  
Courtesy Transportation. Dealers may provide you  
with shuttle service to get you to your destination with  
minimal interruption of your daily schedule. This includes  
one-way or round trip shuttle service within reasonable  
time and distance parameters of the dealer’s area.  
It may not be possible to provide a like-vehicle as a  
courtesy rental.  
Public Transportation or Fuel  
Reimbursement  
Additional Program Information  
If your vehicle requires overnight warranty repairs,  
and public transportation is used instead of the dealer’s  
shuttle service, the expense must be supported by  
original receipts and can only be up to the maximum  
amount allowed by GM for shuttle service. In addition,  
for U.S. customers, should you arrange transportation  
through a friend or relative, limited reimbursement for  
reasonable fuel expenses may be available. Claim  
amounts should reflect actual costs and be supported  
by original receipts. See your dealer for information  
regarding the allowance amounts for reimbursement  
of fuel or other transportation costs.  
All program options, such as shuttle service, may not be  
available at every dealer. Please contact your dealer  
for specific information about availability. All Courtesy  
Transportation arrangements will be administered  
by appropriate dealer personnel.  
General Motors reserves the right to unilaterally modify,  
change or discontinue Courtesy Transportation at  
any time and to resolve all questions of claim eligibility  
pursuant to the terms and conditions described  
herein at its sole discretion.

an acceptable choice to maintain your vehicle’s originally  
designed appearance and safety performance, however,  
the history of these parts is not known. Such parts are not  
covered by your GM New Vehicle Limited Warranty, and  
any related failures are not covered by that warranty.  
Collision Damage Repair  
If your vehicle is involved in a collision and it is  
damaged, have the damage repaired by a qualified  
technician using the proper equipment and quality  
replacement parts. Poorly performed collision repairs  
diminish your vehicle’s resale value, and safety  
performance can be compromised in subsequent  
collisions.  
Aftermarket collision parts are also available. These are  
made by companies other than GM and may not have  
been tested for your vehicle. As a result, these parts may  
fit poorly, exhibit premature durability/corrosion problems,  
and may not perform properly in subsequent collisions.  
Aftermarket parts are not covered by your GM New  
Vehicle Limited Warranty, and any vehicle failure related  
to such parts are not covered by that warranty.  
Collision Parts  
Genuine GM Collision parts are new parts made with  
the same materials and construction methods as the  
parts with which your vehicle was originally built. Genuine  
GM Collision parts are your best choice to ensure that  
your vehicle’s designed appearance, durability, and  
safety are preserved. The use of Genuine GM parts  
can help maintain your GM New Vehicle Warranty.  
Repair Facility  
We recommend that you choose a collision repair  
facility that meets your needs before you ever need  
collision repairs. Your dealer/retailer may have a  
collision repair center with GM-trained technicians and  
state of the art equipment, or be able to recommend  
a collision repair center that has GM-trained technicians  
and comparable equipment.  
Recycled original equipment parts may also be used for  
repair. These parts are typically removed from vehicles  
that were total losses in prior crashes. In most cases, the  
parts being recycled are from undamaged sections of the  
vehicle. A recycled original equipment GM part, may be

Insuring Your Vehicle  
If a Crash Occurs  
Protect your investment in your GM vehicle with  
comprehensive and collision insurance coverage.  
There are significant differences in the quality of  
coverage afforded by various insurance policy terms.  
Many insurance policies provide reduced protection to  
your GM vehicle by limiting compensation for damage  
repairs by using aftermarket collision parts. Some  
insurance companies will not specify aftermarket collision  
parts. When purchasing insurance, we recommend that  
you assure your vehicle will be repaired with GM original  
equipment collision parts. If such insurance coverage  
is not available from your current insurance carrier,  
consider switching to another insurance carrier.  
Here is what to do if you are involved in a crash.  
Check to make sure that you are all right. If you  
are uninjured, make sure that no one else in  
your vehicle, or the other vehicle, is injured.  
If there has been an injury, call emergency services  
for help. Do not leave the scene of a crash until  
all matters have been taken care of. Move  
your vehicle only if its position puts you in danger  
or you are instructed to move it by a police officer.  
Give only the necessary and requested information  
to police and other parties involved in the crash.  
Do not discuss your personal condition, mental  
frame of mind, or anything unrelated to the crash.  
This will help guard against post-crash legal action.  
If your vehicle is leased, the leasing company may  
require you to have insurance that assures repairs with  
Genuine GM Original Equipment Manufacturer (OEM)  
parts or Genuine Manufacturer replacement parts.  
Read your lease carefully, as you may be charged  
at the end of your lease for poor quality repairs.  
If you need roadside assistance, call GM Roadside  
Assistance. See Roadside Assistance Program on  
page 7-8 for more information.  
If your vehicle cannot be driven, know where the  
towing service will be taking it. Get a card from  
the tow truck operator or write down the driver’s  
name, the service’s name, and the phone number.  
Remove any valuables from your vehicle before it is  
towed away. Make sure this includes your insurance  
information and registration if you keep these  
items in your vehicle.

Gather the important information you will need from  
the other driver. Things like name, address, phone  
number, driver’s license number, vehicle license  
plate, vehicle make, model and model year, Vehicle

Managing the Vehicle Damage Repair  
Process  
In the event that your vehicle requires damage repairs,  
GM recommends that you take an active role in its repair.  
If you have a pre-determined repair facility of choice, take  
your vehicle there, or have it towed there. Specify to the  
facility that any required replacement collision parts be  
original equipment parts, either new Genuine GM parts  
or recycled original GM parts. Remember, recycled parts  
will not be covered by your GM vehicle warranty.  
If possible, call your insurance company from  
the scene of the crash. They will walk you through  
the information they will need. If they ask for a  
police report, phone or go to the police department  
headquarters the next day and you can get a copy of  
the report for a nominal fee. In some states/provinces  
with “no fault” insurance laws, a report may not be  
necessary. This is especially true if there are no  
injuries and both vehicles are driveable.  
Insurance pays the bill for the repair, but you must  
live with the repair. Depending on your policy limits,  
your insurance company may initially value the repair  
using aftermarket parts. Discuss this with your repair  
professional, and insist on Genuine GM parts. Remember  
if your vehicle is leased you may be obligated to have  
the vehicle repaired with Genuine GM parts, even if your  
insurance coverage does not pay the full cost.  
Choose a reputable collision repair facility for your  
vehicle. Whether you select a dealer/retailer or a  
private collision repair facility to fix the damage,  
make sure you are comfortable with them.  
Remember, you will have to feel comfortable  
with their work for a long time.  
If another party’s insurance company is paying for  
the repairs, you are not obligated to accept a repair  
valuation based on that insurance company’s collision  
policy repair limits, as you have no contractual limits with  
that company. In such cases, you can have control of  
the repair and parts choices as long as cost stays within  
reasonable limits.  
Once you have an estimate, read it carefully and  
make sure you understand what work will be  
performed on your vehicle. If you have a question,  
ask for an explanation. Reputable shops welcome  
this opportunity.

Vehicle Data Recording and  
Privacy  
Your GM vehicle has a number of sophisticated  
For Credit Card Orders Only  
computers that record information about the vehicle’s  
performance and how it is driven. For example, your  
vehicle uses computer modules to monitor and control  
engine and transmission performance, to monitor the  
conditions for airbag deployment and deploy airbags  
in a crash and, if so equipped, to provide antilock braking  
to help the driver control the vehicle. These modules  
may store data to help your dealer/retailer technician  
service your vehicle. Some modules may also store data  
about how you operate the vehicle, such as rate of fuel  
consumption or average speed. These modules may also  
retain the owner’s personal preferences, such as radio  
pre-sets, seat positions, and temperature settings.

Important: EDR data is recorded by your vehicle only  
if a non-trivial crash situation occurs; no data is recorded  
by the EDR under normal driving conditions and no  
personal data (e.g., name, gender, age, and crash  
location) is recorded. However, other parties, such  
as law enforcement, could combine the EDR data  
with the type of personally identifying data routinely  
acquired during a crash investigation.  
Event Data Recorders  
This vehicle has an Event Data Recorder (EDR).  
The main purpose of an EDR is to record, in certain  
crash or near crash-like situations, such as an airbag  
deployment or hitting a road obstacle, data that will assist  
in understanding how a vehicle’s systems performed.  
The EDR is designed to record data related to vehicle  
dynamics and safety systems for a short period of time,  
typically 30 seconds or less. The EDR in this vehicle is  
designed to record such data as:  
To read data recorded by an EDR, special equipment  
is required, and access to the vehicle or the EDR  
is needed. In addition to the vehicle manufacturer,  
other parties, such as law enforcement, that have the  
special equipment, can read the information if they  
have access to the vehicle or the EDR.  
How various systems in your vehicle were operating  
Whether or not the driver and passenger safety belts  
were buckled/fastened  
GM will not access this data or share it with others  
except: with the consent of the vehicle owner or, if the  
vehicle is leased, with the consent of the lessee; in  
response to an official request of police or similar  
government office; as part of GM’s defense of litigation  
through the discovery process; or, as required by law.  
Data that GM collects or receives may also be used for  
GM research needs or may be made available to others  
for research purposes, where a need is shown and the  
data is not tied to a specific vehicle or vehicle owner.  
How far, if at all, the driver was pressing the  
accelerator and/or brake pedal  
How fast the vehicle was traveling  
This data can help provide a better understanding of the  
circumstances in which crashes and injuries occur.
