WARNING
If you uncouple atrailer with an engaged over-
run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses ar isk of injury.
Do not uncouple atrailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneat hthe vehicle. This
poses arisk of injury.
Make sure that no-one is in the immediate
vicinit yofthe wheel arch or underneat hthe
vehicle when disconnectin gthe trailer cable.
! Do not disconnect
atrailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
! Remove the installed adapter cable before
folding in the ball coupling. Otherwise, dam-
age may occur to the rear bumper and the

! You can connect accessories to the perma-
nent power supply up to amaximum of 240 W.
You cannot charge atrailer battery using the
power supply.
When it leaves the factory, your vehicle's trailer
socket is equipped with apermanen tpower
supply and apower supply that is switched on
via the ignition lock.
The permanen tpower supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin 10.
The trailer's permanen tpower supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
You can find more information about fitting the

tively (Y page 145). Failure check for LEDs
If LED lamps are fitted in the trailer, amalfunc-
tion message may appear in the multifunction
