Power socket for trailer
The vehicle is fitted with a 13-pole power
socket for the connection between the trailer
and the vehicle. With the engine running,
electrical devices on the trailer receive power
from the electrical 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
receive electricity through this connection
(pins 9 and 10). Pin 9 has a permanent live.
This powers, 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
or pin 13 to each other.
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
comply 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 and towing bracket.
●
If the trailer is electrically connected to the
towing vehicle through the trailer power sock-
et.
●
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.
When the vehicle is locked, the alarm is trig-
gered if the electrical connection with the
trailer is cut off.
Before hitching or unhitching a trailer, always
turn off the anti-theft alarm. Otherwise, the tilt
sensor could cause the alarm to go off.
Trailers with LED tail lights
For technical reasons, trailers fitted with LED
rear lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not go off when the electrical connection
with the trailer is cut if it has rear lights with
light-emitting diodes.
WARNING
If the cables are improperly or incorrectly
connected, it may lead to an excessive
amount of current supplied to the trailer,
which can cause abnormalities in the entire
vehicle electronic system, as well as acci-
dents and serious injuries.
●
Ensure that any repairs that need to be
carried out on the electrical system are
carried out by a specialised workshop.
●
Never connect the trailer's electric sys-
tem directly to the electrical connections
of the tail lights or any other power sour-
ces.
WARNING
Contact between the pins of the trailer
power socket can cause short circuits,
overloading of the electrical system or
