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 
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 an object is approx. 2 ft/60 cm from 
the corner sensors, or approx. 5 ft/1.50 m from 
the center sensors.
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. 1 sec-
ond when you engage reverse gear 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.
Signal tones
When nearing an object, its position is indicated 
correspondingly by an interval tone. 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.
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. When 
using a high-pressure cleaner, do not spray the 
sensors for extended periods of time and only 
from a distance of at least 1 ft/30 cm.
PDC with visual warning
The approach of the vehicle to an object is 
shown on the Control Display. Objects that are 
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display 
appears on the Control Display as soon as PDC 
is activated.
