Headlight courtesy delay featureThe low beams stay lit for a short while if the
headlight flasher is switched on after the radio-
ready state is switched off.
Setting the duration
On the Control Display:1."Settings"2."Lighting"3."Pathway lighting:"4.Set length of time.
Settings are stored for the profile currently in
use.
Automatic headlight control
Position of switch  
  : the low beams are acti‐
vated and off automatically, e.g., in tunnels, in
twilight or if there is precipitation. The indicator
lamp in the instrument cluster lights up.
When emerging from a tunnel during the day,
the low beams are not switched off immedi‐
ately but instead only after approx. 2 minutes.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams always stay on when the fog
lights are activated.
Personal responsibility
The automatic headlight control cannot
serve as a substitute for your personal judg‐
ment in determining when to turn the lights on
in response to ambient lighting conditions.
E. g. the sensors are unable to detect fog or
hazy weather. To avoid safety risks under
these conditions, you should always switch on
the lights manually.◀
Daytime running lights With the ignition switched on, the daytime run‐
ning lights light up in position  
  ,    or 
  . After the ignition is switched off, the park‐
ing lights light up in position  
  .
Activating/deactivating
In some countries, daytime running lights are
mandatory, so it may not be possible to deacti‐
vate the daytime running lights.
On the Control Display:1."Settings"2."Lighting"3."Daytime running lamps"
Settings are stored for the profile currently in
use.
Roadside parking lights
The vehicle can be illuminated on one side.
Switching on With the ignition switched off, press the lever
either up or down past the resistance point for
approx. 2 seconds.
Switch off Briefly press the lever to the resistance point in
the opposite direction.
Adaptive Light Control The concept
Adaptive Light Control is a variable headlight
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐ rameters, the light from the headlight follows
the course of the road.

▷By the rear middle sensors at approx.
5 ft/1.50 m.
To ensure full functionality:
▷Do not cover sensors, e.g., with stickers,
bicycle racks.▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Avoid driving fast with PDC
Avoid approaching an object too fast.
Avoid driving off fast while PDC is not yet ac‐
tive.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Overview
With front PDC: button in vehicle
PDC Park Distance Control
Switching on/off
Switching on automatically With the engine running, engage lever in posi‐
tion P R.
Automatic deactivation during forward travel
The system switches off when a certain driving
distance or speed is exceeded.
Switch the system back on if needed.
With front PDC: switching on/off
manually
Press button.▷On: the LED lights up.▷Off: the LED goes out.
Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the
vehicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume set‐
tings of the radio.
