General information
Position of switch: 0,
,
If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these reel settings.
Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to reel on the
one-sided roadside parking lights, refer to
page 104.
Low beams Position of switch
with the ignition
switched on: the low beams light up.
Welcome lights
When parking the vehicle, leave the reel in po‐
sition
or : the parking and interior
lights light up briefly when the vehicle is un‐
locked.

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 0,
or .
After the ignition is switched off, the parking
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.
In tight curves, e.g., on mountainous roads or
when turning, an additional, corner-illuminating
lamp is switched on that lights up the inside of
the curve when the vehicle is moving below a certain speed.

The High-beam Assistant can be switched off
when manually adjusting the light. To reacti‐
vate the High-beam Assistant, press the but‐
ton on the turn signal lever.
System limits Personal responsibility
The High-beam Assistant cannot serve
as a substitute for the driver's personal judg‐
ment of when to use the high beams. There‐
fore, manually reel off the high beams in situa‐
tions where required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
