towing bracket is properly secured at regu-
lar intervals.
T
railer tail light clusters
The trailer tail light clusters must work cor-
rectly and meet legal requirements. Do not
exceed the maximum power consumption
for the trailer tail light clusters.
WARNING
If the towing bracket is unsuitable or in-
c
orrectly fitted, the trailer could become
detached from the towing vehicle. This
can cause serious accidents and fatal in-
juries.
·
Do not carry out any alterations to the
exhaust or brake systems.
NOTICE
The vehicle electronics may be damaged if
the trailer's power consumption is too high.
·
Never connect the trailer’s electrical sys-
tem directly to the electrical connections
of the tail light clusters or to other power
sources. Use only suitable connections to
supply power to the trailer.
We recommend additional services
between the normal inspection inter-
vals if the vehicle is used frequently for
towing a trailer.
Hitching the trailer
Please refer to and at the start
of the chapt
er on page 272.
Trailer socket
A 13-pin trailer socket makes the electrical
connection between the towing vehicle
and the trailer. The pin assignment corre-
sponds to DIN ISO 11446.
If the trailer has a 7-pin plug you will need
to use a suitable adapter.
1. Li the closure cap of the socket and
insert the connector.
2. Turn the connector clockwise a quarter
of a turn until it fully engages in the
socket.
3. Release the closure cap to lock the con-
nec
tor.
4. Check the function of the entire lighting
system before driving o.
If you are uncertain whether the electrical
connection of the trailer with the vehicle is
correct, please contact a suitably qualified
workshop.
Emergency breakaway cable
Always fasten the trailer's emergency
breakaway cable properly to the towing ve-
hicle. 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.
Connection to the anti-the alarm
The trailer is integrated in the anti-the
system if the following conditions are fulfil-
led:
— When the vehicle has a factory-fitted an-
ti-the alarm and a factory-fitted towing
bracket.
— When the trailer is electrically connected
to the towing vehicle via the trailer sock-
et.
— When the vehicle and trailer electric sys-
tems are functional, fault-free and un-
damaged.
— When the vehicle is locked with the vehi-
cle key and the anti-the alarm is active.
When the vehicle is locked, the alarm will
be triggered as soon as the electrical con-
nection to the trailer is interrupted.
Connection to the anti-the alarm
(trailer with LED tail light clusters)
For technical reasons, trailers with LED tail
lights cannot be integrated into the anti-
the alarm system.
When the vehicle is locked, the alarm is not
triggered as soon as the electrical connec-
tion to the trailer with LED rear lights is in-
terrupted.
WARNING
Any electrical cables which are not con-
nec
ted properly or are connected incor-
rectly could cause a power surge to the
