Power socket for trailer
The v
ehicle is fitted with a 13-pole power socket
for the connection between the trailer and the
vehicle. With the engine running, electrical devi-
ces on the trailer receive power from the elec-
trical connection (pin 9 and pin 10 of the trailer
power socket).
If the system detects that a trailer has been
connected, the consumers on the trailer will re-
ceive electricity through this connection (pins 9
and 10). Pin 9 has a permanent live. This pow-
ers, for example, the trailer's interior lighting.
Electrical devices such as a fridge in a caravan
only receive electrical power if the engine is
running (through pin 10).
To avoid overloading the electrical system, you
cannot connect the ground wires of pin 3, pin 11
or pin 13.
If the trailer has a 7-contact connector, you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not be
available.
Tow cable
The tow rope must always be securely fixed to
the towing vehicle and loose enough so that the
vehicle can handle turns smoothly. However,
make sure that the cable does not rub on the
ground while driving.
Trailer tail lights
Always check the trailer's rear lights to ensure
they are working correctly and that they com-
ply with the relevant safety regulations. Make
sure that the maximum permissible power that
can be absorbed by the trailer is not exceeded

Include in the anti-theft alarm
The trailer is included in the anti-theft system if
the following conditions are met:
●
If the vehicle is factory-equipped with an
anti-theft alarm.
●
If the vehicle is factory-equipped with a tow
bracket.
●
If the trailer is electrically connected to the
towing vehicle through the trailer power socket.
●
If the electrical systems of the vehicle and
trailer are in perfect condition and have no
faults or damage.
●
If the vehicle is locked with the key and the
anti-theft alarm is activated.
