General information
Position of switch:
, ,
If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these switch 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 switch on the
one-sided roadside parking lights, refer to
page 94.
Low beams Position of switch
with the ignition
switched on: the low beams light up.
Welcome lights
When the vehicle is parked, leave the switch in
position

In tight curves, e.g., on mountainous roads or
when turning, one of the two front fog lights is
switched on as a turning lamp. As a result the
inside of the curve is better lighted.
ActivatingPosition of switch
with the ignition
switched on.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driv‐
er's side when the vehicle is at a standstill.
The turning lights are automatically switched
on depending on the steering angle or the use
of turn signals.
When driving in reverse, the turning lights may
be automatically switched on regardless of the
steering angle.
Malfunction A Check Control message is displayed.
Adaptive Light Control is malfunctioning or has
failed. Have the system checked as soon as
possible.
High-beam Assistant
The concept When the low beams are activated, this system
automatically switches the high beams on and
off or suppresses the light in the areas that
blind oncoming traffic. The procedure is con‐
trolled by a camera on the front of the interior
rearview mirror. The assistant ensures that the
high beams are activated whenever the traffic
situation allows. The driver can intervene at
any time and switch the high beams non and
off as usual.
Note 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.◀
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams. Depend‐
ing on the version of the system in the vehicle, the high beams may not switch off for oncom‐
ing vehicles, but may only be dimmed in the
areas that blind oncoming traffic. In this case,
the blue indicator light will stay on.

manually▷High beams on, arrow 1.▷High beams off/headlight flasher, arrow 2.
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
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.Fog lights
Front fog lights
The low beams must be switched on.
Press button. The green indicator
lamp lights up.
If the automatic headlight control, refer to
page 94, is activated, the low beams will come
on automatically when you switch on the front
fog lights.
When the high beams or headlight flasher are
activated, the front fog lights are not switched
on.
Instrument lighting Adjusting The parking lights or low beams
must be switched on to adjust
the brightness.
Adjust the brightness with the
thumbwheel.
Interior lights
General information The interior lights, footwell lights, access lights
and courtesy lights are controlled automati‐
cally.

Brake force display
The concept▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this
situation, it is recommended that the driver
takes a break.
Note Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:▷Personal driving style, e.g., steering behav‐
ior.▷Driving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:
▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering fast.▷In active driving situations, such as when
changing lanes frequently.▷When the road surface is poor.▷In the event of strong side winds.Seite 119SafetyControls119
