Park Distance Control PDC*
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 vehicle. To measure 
the distance, there are four ultrasonic sensors 
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not 
sound until the sensors at the front
and at the 
two rear corners are approx. 24 in/60 cm away 
from the object and the middle rear sensors are 
approx. 5 ft/1,50 m away from it.
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, physical circumstances may lead to the 
system warning being issued too late.

Switching on automatically
With the engine running or the ignition switched 
on, the system is activated after approx. one 
second when you shift into reverse or move the 
automatic transmission selector lever to 
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above 
approx. 20 mph/approx. 30 km/h, the system 
switches off and the LED goes out.
Switching on manually*
Press the button; the LED lights up.
Switching off manually*
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated 
correspondingly by an interval tone. For exam-
ple, if an object is detected behind the vehicle, 
the signal tone sounds from the rear. 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.
An interval tone is interrupted after approx. 
3 seconds
>
If you remain in front of an object that has 
been detected by only one of the corner 
sensors
>
If you are driving parallel to a wall.
