prox. 2 seconds and the vehicle will begin rolling
back.◀
Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving.
Power steering provides strong support at low
speeds, which means that less effort is needed
to turn the wheels. Power steering support less‐
ens as your speed increases.
Malfunction The warning lamp lights up.A mes‐
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Have the system checked as soon as pos‐
sible.

Park Distance Control PDC
The concept
In addition to the PDC Park Distance Control, the
backup camera, refer to page 102, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your ve‐
hicle is announced by:▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sensors
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 vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
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 physical
limits of ultrasonic measurement, for instance:▷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 garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
With the engine running or the ignition switched
on, shift the selector lever into position R.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.

Switching on/off manually
Press the button.
▷On: the LED lights up.▷Off: the LED goes out.
Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:
▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.Volume
You can set the volume of the PDC signal tone,
refer to page 161.
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach to an object can be shown on the
Control Display. Objects that are farther away
are displayed on the Control Display before a
signal tone sounds.
The display appears as soon as PDC is acti‐
vated.
If the last image selected was the rear view cam‐
era, this is displayed again. To switch to PDC:
"Switch off rear view camera"
The setting is stored for the remote control cur‐
rently in use.

operated uses an alternating-code system.
Read the operating instructions of the system or
press and hold the programmed button on the
interior rearview mirror. If the LED on the interior
rearview mirror flashes rapidly at first and then
lights up continuously for 2 seconds, the system
is equipped with an alternating-code system.
This flashing LED pattern repeats itself for ap‐
prox. 20 seconds.
In systems with an alternating-code system, the
Universal Garage Door Opener and the system
must be additionally synchronized.
Please obtain additional information on syn‐
chronization in the operating instructions of the
system being set up.
