PDC Park Distance Control*
Limitations of ultrasonic measurement
The detection of objects can come up against
the limitations of physical ultrasonic measure-
ment, for example:

Optical displays
Low objects that have already been displayed,
e.g. curbs, can disappear again from the detec-
tion area of the sensors before or after a contin-
uous tone sounds.
Measurement
Ultrasonic sensors in the bumpers carry out the
measurement.
Higher, protruding objects, e.g. ledges, cannot
be detected.
Their range is approx. 7 ft/2 m.

Avoid approaching an object too quickly.
Avoid starting off quickly while PDC is not
yet activated.
Automatic activation
Otherwise, physical circumstances could cause
the system to issue a warning late.<
With the engine running or the ignition switched
on, shift the selector lever into position R.
Automatic deactivation
The system switches off and the LED goes out:
