Pin Meaning
13 Earth for pin 9
Power socket for trailer
The vehicle is tted with a 13-pole power
socket for the connection between the trailer
and the vehicle. With the engine running, elec-
trical 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, 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 xed to
the towing vehicle and loose enough so that
the vehicle can handle turns smoothly. How-
ever, 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. If you
connect the trailer to the factory-mounted
system, when you turn on the rear fog lamp,
the fog lamp of the towing vehicle will turn o
to turn on the trailer fog lamp.
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.
When the vehicle is locked, the alarm is trig-
gered if the electrical connection with the
trailer is cut o.
Before hitching or unhitching a trailer, always
turn o the anti-theft alarm. Otherwise, the tilt
sensor could cause the alarm to go o.
Trailers with LED tail lights
For technical reasons, trailers tted with LED
rear lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does not
go o when the electrical connection with the
trailer is cut if it has rear lights with light-emit-
ting 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 car-
ried out by a specialised workshop.
●
Never connect the trailer's electric system
directly to the electrical connections of the
tail lights or any other power sources.
