PDC Park Distance Control
*
The concept PDC provides extra safety and conve-
nience during parking maneuvers. Sig-
nal tones indicate the current distance
to an object behind or in front of your
vehicle. To do this, four ultrasonic sen-
sors in the front and rear bumpers each
measure the distance to the nearest
object. The detection range of the front
sensors and the two sensors located at
the ends of the rear bumper is approx.
2 ft/60 cm, while the rear center sen-
sors can detect objects to a distance
of approx. 5 ft/1.50 m.
PDC is a parking aid that can
indicate objects when they are
approached slowly, as is usually the
case when parking. Avoid approaching
objects too fast, otherwise the system
may give warning of physical obstacles
too late.<
Automatic operationThe system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the R position with the ignition
key in position 2. Wait this short period
before backing up. The system
switches off when you shift back out
of reverse.
Manual activation Press the button, the indicator lamp
lights up. Manual deactivation Press the button again; the indicator
lamp goes out.Automatic deactivationAfter driving a distance of more than
approx. 160 ft/50 m or exceeding a
speed of approx. 20 mph/30 km/h, the
system switches off and the indicator
lamp goes out. You may switch the sys-
tem on again manually as needed. 530de418
