The schematics divide the entire vehicle electrical system into individual circuits. Interacting  
electrical components are shown on one common schematic.

FUSE DETAILS

Switches and other components are represented in such a way that their general layout and  
function are self–explicit. They are arranged on the sheet such that the current path can be  
followed from positive (top) to negative (bottom).  
Important: The components and wires are not drawn to scale. For instance, a lead with a length  
of over 1m can be shown as a lead that is only a few cm long. To ensure clear arrangement , all  
connectors, lines branches and connected components from the fuses to the component and  
from the component to ground connection are not shown within the individual cells. If required,  
reference can be made to cells 0670.3 Fuse Details and 0670.4 Ground Distribution where all  
lines are illustrated with all plug connections, line branches and connected components.

INTRODUCTION

General Conventions  
1. Switches and relays are always shown in rest position (e.g. K11).  
6. The dashed line with an arrow at splice X452 indicates that several wires  
lead to splice X452. All lines leading to the connection are illustrated in  
cell 6100.0 Central Body Electronics (ZKE). An interrupted line with an  
arrow indicates that only this one wire leads to another circuit.  
2. A component shown in a dashed frame signifies that the component is  
illustrated only in part (e.g. P90 and P91).  
3. A component shown in a completely drawn frame signifies that the  
component is illustrated in full (e.g. K11).  
7. The dashed line from pin 4 of connector X293 to ground X493 shows the  
ground supply for relay K11. If required, refer to cell 0670.4 Ground  
Distribution at ground X493 for the complete line progression with all plug  
connections, line branches, wire colors, and cross sections.  
4. The dashed line between pin 8 and pin 6 of connector X293 indicates  
that both pins belong to connector X293.  
8. The interrupted line from splice X452 with an A in the open arrow is  
continued on page 6160.0–02.  
Termination of wire 4 VI/SW from splice X452 with a wavy line indicates that  
the wire is continued on the opposite page.  
5. The dashed line from fuse F1 to pin 8 of connector X293 shows the  
positive supply of relay K11. If required, refer to cell 0670.3 Fuse Details at  
fuse F1 for the complete line progressing with plug connections, line  
branches, wire colors and cross sections.
