Electrical socket for trailer
The vehicle is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
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.
Trailer maximum electricity consumption
Brake lights (total) 84 Watts
Turn signal, on each side 42 Watts
Side lights (total) 100 Watts
Rear lights (total) 42 Watts
Rear fog light 42 Watts
Never exceed the values indicated!
Note
●
If the rear lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
●
If the trailer absorbs excessive electric cur-
rent, the vehicle electronics may be dam-
aged.
●
Never connect the trailer's electric system
directly to the electrical connections of the
tail lights or any other power sources. Only
use the connections intended for providing
electric current to the trailer.
Ball coupling of towing bracket*
The ball coupling is provided with instruc-
tions on fitting and removing the ball cou-
pling of the towing bracket.
WARNING
The towing bracket ball coupling must be
stored securely in the luggage compartment
to prevent them being flung through the vehi-
cle and causing injury.
Note
●
By law, the ball coupling must be removed
if a trailer is not being towed if it obscures
the number plate.
Driving tips
Driving with a trailer always requires extra
care.
Weight distribution
The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
