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.
Connection to the anti-theft alarm (trailer with LED tail light clusters)
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.
WARNING
Any electrical cables which are not connected properly or are connected incorrectly could cause a power surge to
the trailer. This could lead to faults in the entire vehicle electronics system and could also cause accidents and
serious injuries.
● All work on the electrical system should only be carried out by a qualified workshop.
● Never connect the trailer's electrical system directly to the electrical connections of the towing vehicle's tail light
clusters or to other power sources.
WARNING
Contact between the pins in the trailer socket can lead to short circuits, overloading of the electrical system and
failure of the lighting system, thereby causing accidents and serious injuries.
● Never connect the pins in the trailer socket to one another.
● Have bent pins repaired by a qualified workshop.
NOTICE
If you park the trailer using the support wheel or other trailer supports, disconnect the trailer from the vehicle. The
vehicle could move up and down if the load changes or if there is damage to the tyres, for example. If this happens,
a great deal of force will be exerted on the towing bracket and trailer, which could lead to damage to the vehicle
and trailer.
If there is a fault in the vehicle or trailer electrical systems or if there is a fault in the anti-theft alarm, have the
vehicle checked by a qualified workshop.
If the engine is not running and electrical equipment is switched on in the trailer via the trailer socket, the 12-
volt vehicle battery will discharge.
If the 12-volt vehicle battery charge level is low, the electrical connection to the trailer will be interrupted
automatically.
Loading the trailer
Trailer weight and drawbar load
The maximum trailer weight is the weight that the vehicle can pull→
.
The drawbar load is the weight that the towing bracket exerts on the ball coupling neck vertically from above.
