PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Audible signals and an optical display indicate
that you are approaching an object in front of or
behind your vehicle. To measure the distance,
four ultrasonic sensors are provided in each
bumper. The range of these sensors is approx.
6 ft/2 m. However, an acoustic warning begins
to sound for the sensors at the front and at the
two rear corners 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; oth-
erwise, the system may sound the warning of
physical obstacles too late.<
Automatically activating
The system is activated approx. 1 second after
you engage the transmission position R with
the engine running or the ignition switched on.
Wait this short period before proceeding.
Manual activation
Press the 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 switches
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 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 Info Display. PDC has failed.
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.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are displayed there before a
signal tone begins to sound.
iDrive, for principle details, refer to page16.

3Automatic headlamp control, daytime run-

* and Adaptive Head Light*
If you open the driver's door when the ignition is
switched off, then the exterior lighting is
switched off if the light switch is in position0, 2
or3.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched 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 preferable to
switch on the left-hand or right-hand roadside
parking lamps, refer to page101.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for example in a tunnel, at dawn and dusk,
and in case of precipitation. The LED next to the symbol is illuminated when the low beams are
on.
The low beams may be switched on when the
sun is low on the horizon in a clear sky.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps.<
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 or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
After parking the vehicle and switching off the
headlamps, you can use the headlamp flasher
control to activate the low beams for a period of
roughly 40 seconds.
Pressing the button on the remote control,
refer to page32, also switches on the low
beams for approx. 40 seconds. In addition, the
door handle and interior lamps are switched on
for approx. 10 seconds.
Daytime running lamps*
The daytime running lamps light up in posi-
tion0, 1 or3. The light output is lower than with
the low-beam headlamps.
If the light switch remains in position1, then the
parking lamps are lit after the ignition is
switched off.
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumina-
tion of the road surface. Depending on the
steering angle and other parameters, the light
