Park Distance Control PDC*
The principle
PDC assists you when manoeuvring into a park-
ing 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 range of these sensors is approx.
2 m, approx. 7 ft. However, for the front sensors
and those in both rear corners, an audible warn-
ing will not sound until a range of approx. 60 cm,
approx. 2 ft, and approx. 1.50 m, approx. 5 ft, for
the centre rear 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 in view of the physical
principles involved.<
If the car is towing a trailer, the rear sensors
clearly cannot supply sensible signals and
therefore remain switched off.
Automatic activation
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you move the selector
lever to position R.
Wait briefly before starting to drive, to allow the
system to become active.
Switching on manually
Press the button; the LED comes on.
Switching off manually
Press the button again; the LED goes out.
Once you have driven approx. 50 m, approx.
165 ft, or travelled at a speed of more than
approx. 30 km/h or 20 mph the system is deac-
tivated and the LED goes out. Switch the sys-
tem on again as necessary.
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, approx. 12 in,
the signal becomes continuous.
An intermittent tone is interrupted after approx.
3seconds:
> If you remain in front of an object that was
detected by only one of the corner sensors
> If you are driving parallel to a wall
