MalfunctionThe warning lamp lights up. The sys‐
tem is malfunctioning or has failed.
A message appears on the Control
Display. More information, refer to page  80.
Park Distance Control PDC
The concept In addition to the PDC Park Distance Control,
the backup camera, refer to page  105, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your
vehicle is announced by:▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle may prevent you from hearing the PDC's
signal tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
High, protruding objects such as ledges may
not be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Seite 103Driving comfortControls103

Lamp and bulb replacement
Notes
Lamps and bulbs
Lamps and bulbs make an essential contribu‐
tion to vehicle safety.
The manufacturer of the vehicle recommends
that you entrust corresponding procedures to
the service center if you are unfamiliar with them or they are not described here.
You can obtain a selection of replacement
bulbs at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always switch off the lights af‐
fected to prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlamps
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center.
Due to the high voltage present in the system,
there is the danger of fatal injuries if work is
carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes LED
Light-emitting diodes installed behind translu‐
cent lenses serve as the light source for many
of the controls, displays and other equipment
in your vehicle.
These light-emitting diodes, which operate us‐
ing a concept similar to that applied in conven‐
tional lasers, are officially designated as
Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours; otherwise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the
headlamps in cool or humid weather. When
you drive with the lights switched on, the con‐
densation evaporates after a short time. The
headlamps do not need to be changed.
If the condensation in the headlamps does not
evaporate after trips with the lights switched
on, and the amount of moisture in the head‐
lamps increases, for example if water droplets
form, have them checked by your service cen‐
ter.Seite 250MobilityReplacing components250

other attempt in order to allow the dis‐
charged battery to recharge.3.Let both engines run for several minutes.4.Disconnect the jumper cables in the re‐
verse order.
Check the battery and recharge if necessary.

Adhere to the towing speed and distance
Do not exceed a towing speed of
40 mph/70 km/h and a towing distance of
90 miles/150 km or damage to the transmis‐
sion can occur.◀

Follow all towing instructions, or vehicle
damage or accidents may occur.◀▷Make sure that the ignition is switched on;
otherwise, the low beams, tail lamps, turn
signals, and windshield wipers may be un‐
available.▷Do not tow the vehicle with the rear axle
tilted, as the front wheels could turn.▷When the engine is stopped, there is no
power assist. Consequently, more forceSeite 260MobilityBreakdown assistance260

needs to be applied when braking and
steering.▷Larger steering wheel movements are re‐
quired.▷Switch on the hazard warning system, de‐
pending on local regulations.▷If the electrical system has failed, clearly
identify the vehicle being towed by placing
a sign or a warning triangle in the rear win‐
dow.
Tow truck
sDrive
Vehicles with automatic transmission, 6-gear.
Have your vehicle transported with a tow truck
with a so-called lift bar or on a flat bed.
xDrive
Towing a vehicle with xDrive
Do not tow a vehicle with xDrive with just
the front or rear axle raised; otherwise, the
wheels could lock up and the transfer case
could be damaged.◀
Towing other vehicles
General information Light towing vehicle
Your vehicle must not be lighter than the
vehicle being towed; otherwise, it will not be
possible to control vehicle response.◀
Attaching the tow bar/tow rope correctly
Attach the tow bar or tow rope to the tow
fitting; connecting it to other vehicle parts may
cause damage.◀▷Switch on the hazard warning system, de‐
pending on local regulations.▷If the electrical system has failed, clearly

Towing methods
Do not lift the vehicle
Do not lift the vehicle by the tow fitting or
body and chassis parts; otherwise, damage
may result.◀
Tow bar The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:
▷Clearance and maneuvering capability will
be sharply limited during cornering.▷The tow bar will generate lateral forces if it
is attached offset.
Tow rope
When starting to tow the vehicle, make sure
that the tow rope is taut.
To avoid jerking and the associated stresses
on the vehicle components when towing, al‐
ways use nylon ropes or nylon straps.
