Problem
Possible causes/consequences and
M
MSolutions Only the red segments in
the PARKTRONIC warn-
ing displaysa re lit. You
also hear awarning tone
for approximately two
seconds.
PARKTRONIC is then
deactivated and the indi-
cator lamp on the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has been deactivated.
X If problems persist, have PARKTRONIC checked at aqualified spe-
cialist workshop. Only the red segments in
the PARKTRONIC warn-
ing displaysa re lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X
Clean the PARKTRONIC sensors (Y page 330).
X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X See if PARKTRONIC functions in adifferent location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems

Position the trailer horizontally behind the
vehicle.
X Couple up the trailer.
X Establish the electrical connection between
the vehicle and the trailer.
X Check that the trailer lighting system is work-
ing.
X Push the combination switch upwards/down-
wards
X Check whether the corresponding turn signal
on the trailer is flashing.
Ac onnected trailer is only detected when the
electrical connection is established correctly
and when the lighting system is working prop- erly. The function of other systems, such as
ESP ®
,P ARKTRONIC, Active Parking Assist,
Active Blind Spot Assist or Lane Keeping
Assist also depends on this. Uncoupling
atrailer G
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
adapter cable. X

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
display even if there is no fault. The reason for
the error message may be that the curren thas
fallen below the minimum of 50 mA.
To ensure reliable operation of the failure indi-
cator, each LED chain in the trailer lighting must
be guaranteed aminimum curren tof50mA. Trailer with 7-pin connector
