Trailer socket

A 13-pin trailer socket makes the electrical connection between the towing vehicle and the trailer. When the engine is running, electrical
consumers in the trailer are supplied with voltage via the electrical connections (pin 9 and pin 10 of the trailer socket).
When the vehicle detects a trailer through the electrics, the consumers in the trailer are supplied with electrical current via the electrical
connection (pins 9 and 10). Pin 9 is assigned as the permanent live, enabling operation of e.g. interior trailer lighting. Electrical consumers such
as a caravan refrigerator are supplied with power only when the engine is running (pin 10).
To avoid overloading the electrical system, do not inter-connect the three earth wires (pins 3, 11 and 13).
If the trailer has a 7-pin plug you will need to use a suitable adapter cable. This means that pin 10 cannot be used.

Emergency breakaway cable

Always fasten the trailer's emergency breakaway cable properly to the towing vehicle. Leave enough slack in the emergency breakaway cable so
that the vehicle can still drive around corners. However the emergency breakaway cable should not drag along the ground while you are driving.

Rear trailer lights

Ensure that the trailer lights work properly and meet legal requirements. Do not exceed the maximum power consumption for the trailer
→ Maximum power consumption of the trailer

Connection to the anti-theft alarm

The trailer is integrated in the anti-theft system if the following conditions are fulfilled:
When the vehicle has a factory-fitted anti-theft alarm and a factory-fitted towing bracket.
When the trailer is electrically connected to the towing vehicle via the trailer socket.
When the vehicle and trailer electric systems are functional, fault-free and undamaged.
When the vehicle is locked with the vehicle key and the anti-theft alarm is active.
When the vehicle is locked, the alarm will be triggered as soon as the electrical connection to the trailer is interrupted.
Always switch off the anti-theft alarm when a trailer is being hitched or unhitched. The tilt sensor could otherwise trigger an alarm unnecessarily.
Trailer with LED rear lights
For technical reasons, trailers with LED tail lights cannot be integrated into the anti-theft alarm system.
When the vehicle is locked, the alarm is not triggered as soon as the electrical connection to the trailer with LED rear lights is interrupted.
The driving profile automatically changes to Normal driving profile if the Eco driving profile was selected when the trailer was hitched. If the
connected trailer cannot be recognised, or when using a towing bracket that was not retrofitted by Volkswagen, the Normal driving profile must
be selected manually before towing a trailer. Once the trailer has been unhitched, the ignition must be switched off and on again once to
reactivate the Eco driving profile.
