PDC Park Distance Control
Ultrasound sensors
Ultrasound sensors of the PDC,
for example in the bumpers.
Functional requirements
To ensure full functionality:
▷Do not cover sensors, for example, with
stickers, bicycle racks.
▷Keep the sensors clean and free of ice.
To clean: when using high-pressure washers,
do not spray the sensors for long periods and
maintain a distance of at least 12 inches/30 cm.
Switching on/off
Switching on automatically
PDC switches on automatically in the following
situations:
▷If selector lever position R is engaged when
the engine is running.
The rearview camera also switches on.
▷With front PDC: when obstacles are de‐
tected behind or in front of the vehicle by
PDC and the speed is slower than approx.
2.5 mph/4 km/h.
With front PDC: You can switch off automatic
activation on obstacle detection:
1. "Settings"2."Parking"3.Select setting.
Settings are stored for the profile currently
used.
Automatic deactivation during forward
travel
The system switches off when a certain driving
distance or speed is exceeded.
Switch the system back on if needed.
With front PDC: switching on/off
manually
Press button.
▷On: the LED lights up.▷Off: the LED goes out.
The rearview camera image is displayed when
the reverse gear is engaged by pressing the
button.
Display
Signal tones
When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the ve‐
hicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 inches/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume
The ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.

Settings are stored for the profile currently
used.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are already displayed on the Con‐
trol Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in col‐
ors: red, green and yellow.
When the image of the rearview camera is dis‐
played, the switch can be made to PDC:

System limits
Information
WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed.◀
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, for exam‐
ple coats.
▷With external interference of the ultra‐
sound, for example from passing vehicles
or loud machines.
▷When sensors are dirty, iced over, damaged
or out of position.
▷If cargo protrudes.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.
▷With tow bars and trailer couplings of other
vehicles.
▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.
▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.
▷For objects with porous surfaces.
Low objects already displayed, for example,
curbs, can move into the blind area of the sen‐
sors before or after a continuous tone sounds.
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 with
ice.
▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, for example, in underground
garages.
▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, for exam‐
ple, sweeping machines, high pressure
steam cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.

With front PDC: to reduce false alarms, switch
off automatic PDC activation on obstacle detec‐
tion, for example in car washes, refer to
page 130.
Malfunction
A Check Control message, refer to page 80, is
displayed in the instrument cluster.
Red symbol is displayed, and the range
of the sensors is dimmed on the Control
Display.
PDC has failed. Have the system checked.
Rearview camera
The concept
The rearview camera provides assistance in
parking and maneuvering backwards. The area
behind the vehicle is shown on the Control Dis‐
play.
Information
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations.◀

Spatially-shaped markings are displayed.
Pathway lines
Pathway lines can be superimposed on the im‐
age of the rearview camera.
Pathway lines help you to estimate the space
required when parking and maneuvering on
level roads.
Pathway lines depend on the current steering
angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can be superimposed on the
image of the rearview camera.
Turning circle lines show the course of the
smallest possible turning radius on a level road.
Only one turning radius line is displayed after
the steering wheel is turned past a certain an‐
gle.
Obstacle marking
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins of the obstacle markings
match the markings of the PDC.

Detection of objects
Very low obstacles or high, protruding objects
such as ledges may not be recognized by the
system.
Assistance functions also take into account data
of the PDC.
Follow instructions in the PDC chapter, refer to
page 129.
The objects displayed on the Control Display
under certain circumstances are closer than
they appear. Therefore, do not estimate the
distance from the objects on the display.
Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Parking assistant handling is divided into three
steps:
▷Switching on and activating.▷Parking space search.▷Parking.
System status and instructions on required ac‐
tions are displayed on the Control Display.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best possi‐
ble parking line and takes control of steering
during the parking procedure.
