Technical features for driving comfort and
safety
Park Distance Control PDC*
The principle
PDC assists you when manoeuvring into
a parking space. Audible signals and a visual
*
display indicate that you are approaching an
object in front of or behind your vehicle. Four
ultrasonic sensors in each bumper measure the
distance from it. The sensors at the front and at
the rear corners have a range of about 60 cm
(2 ft), and the centre rear sensors a range
of about 1.20 m (5 ft).
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 in view of 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 operation
With the ignition key in position 2, the system is
activated automatically after approx. 1 second
when you move the automatic transmission
selector lever to position R.
Wait briefly before starting to drive, to allow the
system to become active.
After a distance of approx. 50 m (164 ft)
has been covered or a speed of approx. 30 km/h
(20 mph) is exceeded, the system is deacti-
vated and the LED goes out. Switch the system
on again manually as necessary.

Switching on manually
Press the button, the LED comes on.
Switching off manually
Press the button again; the LED goes out.
Audible warning signals
The fact that you are approaching an object is
indicated by an intermittent warning signal for
the part of the car in question. For instance, if an
object is identified to the rear left of the car, the
warning signal sounds at the rear left loud-
speaker. The closer the car approaches the
obstruction, the more rapid the sequence of
signals. When the distance from a detected
object is less than approx. 30 cm (12 in), the
signal becomes continuous.
If you are driving parallel to a wall, the signal is
interrupted after approx. 3 seconds.
Malfunction
The LED in the button flashes and a message
appears on the control display. PDC has failed.
Have the system checked.
As a precautionary measure, keep the sensors
clean and free from ice, so that they always
operate reliably.
