Technical features for driving comfort and
safety
Park Distance Control PDC*
The principle
PDC assists you with manoeuvring into a park-
ing space. Acoustic signals warn you of the
presence of an object in front of
car. Four ultrasonic sensors in either bumper
measure the distance to the nearest object.
An acoustic warning sounds once an object is
closer than approx. 60 cm, approx. 2 ft, to the
*
front sensors or rear corner sensors, or
approx. 1.50 m, approx. 5 ft to the rear centre
sensors.
PDC is a parking aid which is capable of
registering objects approached at low
speed, as is usually the case when the car is
being parked. Avoid approaching an object rap-
idly, otherwise the system may be unable to
alert you in sufficient time due to the physical
principles involved.<
If the car is towing a trailer, the rear sensors will
be unable to supply meaningful signals. They
therefore do not come on.
Automatic activation
With the engine running or the ignition switched
on, the system is activated after approx.
1 second when you engage reverse gear or
move the gear selector lever to position R. Wait
briefly before starting to drive, to allow the sys-
tem to become active.

Press the button; the LED comes on.
Switching off manually
Press the button again; the LED will go out.
If you drive for approx. 50 m, approx. 55 yd, or at
a speed exceeding approx. 30 km/h or 20 mph,
the system is deactivated and the LED goes
out. Switch the system on again as necessary.
Audible warning signals
An intermittent tone indicates the position of an
object as the car approaches it. For example,
the tone sounds at the rear if the system
detects an object behind the car. The closer the
car approaches the object, the more rapid the
sequence of signals. When the distance to a
detected object is less than approx. 30 cm,
approx. 12 in, the signal becomes continuous.
An intermittent tone is interrupted after approx.
3 seconds:

Malfunction
As a precautionary measure, keep the sensors
clean and free from ice, so that they always

detected by only one of the corner sensors
If you are driving parallel to a wall.
The indicator light in the instrument
cluster comes on. PDC has failed.
Have the system checked.
