PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical displays
alert
you to the approach of an object in front of
*
or
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in each
bumper. The range of these sensors is approx.
7 ft/2 m. But an acoustic warning only sounds at
approx. 24 in/60 cm for the sensors at the
front
*
and at the two rear corners and at approx.
5 ft/1,50 m for the middle sensors at the rear.
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, oth-
erwise the physical circumstances would mean
that the system warning was too late.

Automatic activation
Whenever the engine is running or the ignition
is on, each time you move the selector lever into
position R, the PDC system is activated after
approx. 1 second.
Wait this short period before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc. As the distance between
vehicle and object decreases, the intervals
between the tones become shorter. If the dis-
tance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3 seconds:
>
if you remain in front of an object that was
only detected by one of the corner sensors
>
if you drive parallel to a wall
Adjusting
You can adjust the volume of the warning tones
if the vehicle is equipped with a single drive,
refer to page
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.
