PDC Park Distance Control*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
in front of
* or behind your car. To measure the
distance, there are four ultrasonic sensors in
each bumper. The sensors at the front
* and at
the two rear corners have a range of approx.
24 in/60 cm; the rear middle sensors have
approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, as
otherwise physical circumstances may lead to
the system warning being issued too late.<
Automatic mode
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.
Manual operation*
Press the button, the LED lights up.
Deactivating manual mode
Press the button again; the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 165 ft/50 m or exceeds a speed of roughly 20 mph or 30 km/h;
the LED goes out. You can reactivate the sys-
tem manually as needed.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, the tone sounds at the rear if the system
detects an object behind the car. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
The warning signal is canceled after approx.
3 seconds, if you are moving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively.
Manual mode
The LED above the button flashes in addition.
PDC with optical warning
You can also have the system show distances
to objects on the Control Display. The contours
of distant objects are shown on the Control Dis-
play even before the acoustic signal sounds.
The setting is stored for the remote control cur-
rently in use.
