Park Distance Control
PDC
The concept
PDC provides support when parking in reverse.
Signal tones and a visual display indicate that
the vehicle is approaching an object behind it.
Measurements are made by four ultrasound
sensors in the bumpers.
The range of these sensors is approx. 6 ft/2 m.
An acoustic warning is first given:
▷ By the two corner sensors at ap‐
prox. 24 in/60 cm.
▷ By the rear middle sensors at approx.
5 ft/1.50 m.
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to phys‐
ical circumstances. There is risk of injuries or
risk of property damage. Avoid approaching an
object quickly. Avoid driving away quickly while
PDC is not yet active.◀
Automatic operation
The system is activated after approx. one sec‐
ond when reverse gear or selector lever posi‐
tion R is engaged while the engine is running or
the ignition is switched on. Await this short pe‐
riod before setting the vehicle into motion.
Signal tones
The closer the vehicle is to the object, the
shorter the intervals become. If the distance to
a detected object is less than approx.
12 in/30 cm, a continuous tone is sounded.
If the distance remains constant, for example
when driving parallel to a wall, the signal tone
is stopped after approx. 3 seconds.
PDC with visual warning
Displaying the approach to an object on the
Control Display. The contours of distant objects
are displayed on the Control Display before a
signal tone is output. The display is shown on
the Control Display as soon as reverse gear or
selector lever position R is engaged.
System limits
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations.◀
Malfunction
The warning light lights up. A message
appears on the Control Display. PDC is
malfunctioning or has failed. Have the
system checked.
To ensure full functionality of the sensors, keep
the sensors clean and free of ice. When using
high-pressure washers, do not spray the sen‐
sors for long periods and maintain a distance of
at least 12 in/30 cm.
