Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly
R parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R snowfall or heavy rain may lead to aparking
space being measured inaccurately
R pay attention to the PARKTRONIC
(Y page 199) warning messages during the
parking procedure
R you can intervene in the steerin gprocedure to
correc titata ny time. Active Parking Assist
will then be cancelled.
R when transportin gaload which protrudes
from your vehicle, you should not use Active
Parking Assist
R never use Active Parking Assist when snow
chains are fitted
R make sure that the tyre pressures are always
correct. This has adirect influenc eonthe
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Object
slocated above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken
into account when the parking procedure is cal- culated, e.g. overhangin gloads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are object sabove the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in frontoft hese
objects
This could cause acollision. There is arisk of
an accident. If object
sare located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 198).
Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to alow
obstacle such as alow kerb
R you forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
R the parking space is on akerb
R the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. atree, apost or atrailer :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle. 202

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
trailer electric sataqualified specialist work-

X To switch the connected power supply on
or off: turn the key to position 2or 0respec-
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
