First read and observe the introductory information
and safety warnings 
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.
Trailer socket
A 13-pin trailer socket makes the electrical connection between the towing vehicle and the trailer. If the trailer has a 7-pin plug you will need to use an adapter cable.
Rear trailer lights
Ensure that the trailer lights work properly and meet legal requirements. Do not exceed the maximum power consumption for the trailer   .
The trailer is connected to the anti-theft alarm:
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.
