Technology for comfort, convenience and 
safety
PDC Park Distance Control*
The concept
In addition to the PDC Park Distance Control, 
the rear view camera
*
, can 
also be switched on.
PDC assists you during parking. A slow 
approach to an object in front of or behind your 
vehicle is announced by:
>
Signal tones
>
Optical displays
Measurement
Ultrasonic sensors in the bumpers carry out the 
measurement.
Their range is approx. 7 ft/2 m.
The acoustic warning begins:
>
At approx. 24 in/60 cm for the front
*
 sen-
sors and the two rear corner sensors.
>
At approx. 5 ft/1.50 m for the middle sen-
sors in the rear.
System limitations
PDC cannot replace the personal assess-
ment of the traffic situation. Also make a 
direct visual check of the traffic situation around 
the vehicle. Otherwise, there could be a risk of 
accident, for example due to other road users or 
objects outside the detection range of PDC.
Loud sources of sound, inside and outside the 
vehicle, could drown out the PDC signal tone.
<
Avoid approaching an object too quickly. 
Avoid starting off quickly while PDC is not 
yet activated.
Otherwise, physical circumstances could cause 
the system to issue a warning late.

Limitations of ultrasonic measurement
The detection of objects can come up against 
the limitations of physical ultrasonic measure-
ment, for example:
>
When using tow bars and towing hitches
>
In the presence of thin or wedge-shaped 
objects
>
In the presence of low objects
>
In the presence of objects with corners and 
sharp edges
Low objects that have already been displayed, 
e.g. curbs, can disappear again from the detec-
tion area of the sensors before or after a contin-
uous tone sounds.
Higher, protruding objects, e.g. ledges, cannot 
be detected.
False warnings
Under the following conditions, PDC may dis-
play a warning even though no obstacle is 
present in the detection range:
>
In heavy rain
>
When the sensors are heavily soiled or iced-
over
>
When the sensors are covered with snow
>
On rough road surfaces
>
In large, rectangular buildings with smooth 
walls, e.g. underground garages
>
In the presence of heavy exhaust
>
Due to the presence of other ultrasonic 
sources such as street sweepers, steam 
cleaners, or neon lamps.
Automatic activation
With the engine running or the ignition switched 
on, shift the selector lever into position R.
Automatic deactivation
The system switches off and the LED goes out:
