PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical displays
alert
you to the approach of an object in front of
* or
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 only sounds at
approx. 24 in/60 cm for the sensors at the
front
* and at the two rear corners and at approx.
5 ft/1,50 m for the middle sensors at the rear.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an obje ct a t h i g h s p e e d , o t h -
erwise the physical circumstances would mean
that the system warning was too late. <
Automatic activation
Whenever the engine is running or the ignition
i s o n , e a c h t i m e y o u m o v e the selector lever into
position R, the PDC syst em is activated after
approx. 1 second.
Wait this short period before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
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
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a sign al tone from the left
rear speaker, etc. As the distance between
vehicle and object decreases, the intervals
between the tones become shorter. If the dis-
tance to the nearest ob ject falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
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
Adjusting
You can adjust the volume of the warning tones
if the vehicle is equipped with a single drive,
refer to page 90.
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
To prevent this problem, 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 clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.

tive Head Light
*
If you open the driver's door with the ignition
switched off, the exteri or lighting is automati-
cally switched off when the light switch is in
position 0, 2 or 3.
If necessary, switch on the parking lamps,
switch position 1.
Parking lamps
In switch position 1, the front, rear and side
vehicle lighting is switch ed on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is better to switch on
the roadside parking lamp s on one side, refer to
page 112.<
Low beams
The low beams light up wh en the light switch is
in position 2 and the ignition is on.
Automatic headlamp control*
In switch position 3, the system activates the
low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol
lights up when the low beams are on. You can
activate the daytime driving lamps, refer to
page 111. In the situations named above, the
system then automatically switches over to the
low beams.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*. <
The automatic headla mp control cannot
serve as a substitute for your personal
judgment in determin ing when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
low beams manually un der these conditions.<
Welcome lamps
When parking the vehicle, if you leave the light
switch in position2 or 3, the parking lamps and
the interior lamps light up briefly when the vehi-
cle is unlocked.
