Park Distance Control PDC
The concept PDC supports you when parking.
You are alerted that you are slowly approach‐
ing an object behind the vehicle and, if equip‐
ped accordingly, in front of the vehicle by:▷Signal tones.▷A visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle may prevent you from hearing the PDC's
signal tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
High, protruding objects such as ledges may
not be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
