Technology for comfort, convenience and
safety

PDC Park Distance Control*

The concept
In addition to the PDC Park Distance Control,
*
the rear view camera , refer to page 86, 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
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
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

Limitations of ultrasonic measurement
The detection of objects can come up against
the limitations of physical ultrasonic measure-
ment, for example:

>
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

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
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.
