PDC Park Distance Control*

The concept

In addition to the PDC Park Distance Control, the
backup camera*, refer to page

119

, can be

switched on.

PDC supports you when parking. Objects that
you are approaching slowly in front of* or behind
your vehicle are indicated with:

▷

Signal tones.

▷

Visual display.

Measurement

Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:

▷

By the front* sensors and the two rear cor‐
ner 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 vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
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.◀

▷

With tow bars and trailer hitches.
