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.
However, an acoustic warning first sound for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1,50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
otherwise the physical circumstances would
mean that the system warning was too late.<
Automatically activating
The system starts to operate automatically
approx. 1 second after you select reverse gear
or move the selector lever into the R position
with the engine running or the ignition switched
on.
Wait this short period before driving.
Manual activation
Press button, the LED lights up.
Manual deactivation
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
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 signal 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 object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you stop before 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.
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.
PDC with visual warning*
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are already shown there before
a signal tone sounds.

The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.
With the daytime driving lamps
* activated, the
low beams are always switched on when the
ignition is switched on.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In the switch position1, the Adaptive Head
Light is active and the automatic headlamp con-
trol
* is switched on.
To avoid dazzling oncoming traffic, the Adap-
tive Head Light is not active when driving in
reverse and points toward the passenger side
when the vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps

You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not switch them on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the inside rearview mirror controls the process.
The assistant ensures that the high beams are
switched on whenever the traffic situation
allows. This reduces the strain on you while at
the same time providing you with the best pos-
sible visibility. Of course, you can intervene at
any time and switch the high beams on and off
in the accustomed manner.
