Note
During installation special attention has to be paid to the following points:
•
Cables must not be pinched or damaged.
•
All sealing elements have to be installed properly.
•
The socket gasket has to be positioned on the insulating sleeve and not on the individual
wires.
•
Lay the cables such that they do not rub on the vehicle and are not bent.

When a trailer lamp fails (including direction indicator lights, but not back-up light and rear fog
lamp), this is indicated by the light failure indicator in the instrument cluster. An additional
indicator light (C2) for monitoring the direction indicators on the trailer is not provided in the
vehicle.
When a trailer is used, the rear fog lamp of the traction vehicle is deactivated.
In the case of trailers without rear fog lamp, a rear fog lamp has to be retrofitted.
Asocket adapter may only be used in conjunction with a trailer. When the trailer is no longer
used, remove the socket adapter.
Correct trailer operation has to be checked using a trailer or a test instrument with load resistors.
