PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
But an acoustic warning first sounds at approx.
24 in/60 cm for the sensors at the front and two
rear corners and at approx. 5 ft/1,50 m for the
center rear sensors.
PDC is a parking aid that can indicate the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed; otherwise, the physical circumstances
could cause the system warning to be activated
too late.<
Automatically activating
With the engine running or the ignition switched
on, the system starts to operate automatically
approx. 1 second after you shift into reverse.
Wait this short period before driving.
Switching on manually
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
Thus, an object detected to the left rear of the
vehicle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become shorter.
The signal tone becomes continuous once the
distance to the nearest object falls to below
roughly 1 ft/30 cm.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure wash-
ers for prolonged intervals and always keep the
nozzle at least 4 in/10 cm from the sensors.
PDC with visual warning*
You can also enjoy the option of having the sys-
tem show the approach to an object on the
Control Display. Objects that are farther away
are already shown there before a signal tone
sounds.
