92 n 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.
