General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of dan‐
ger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not

NotesUse while driving
If on a rare occasion it is necessary to use
the parking brake while driving, do not use ex‐
cessive force when applying it. When using it,
keep the button on the lever depressed.
Otherwise, using excessive force when applying
the parking brake may cause the rear wheels to
lock, resulting in fishtailing.◀
To prevent corrosion and braking control on one
side only, lightly apply the parking brake period‐
ically while coasting, if traffic conditions permit.
The brake lamps will not light up if the parking
brake is engaged.

If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these switch settings:
Parking lamps
Switch position
: the vehicle lamps light
up on all sides, e.g., for parking.
Do not use the parking lamps for extended pe‐
riods; otherwise, the battery may become dis‐
charged and it would then be impossible to start
the engine.
When parking, it is preferable to switch on the
one-sided roadside parking lamps, refer to
page 87.
Low beams
Switch position
with the ignition switched
on: the low beams light up.

Adaptive light control
The concept
Adaptive light control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.
In tight curves, e.g., on mountainous roads or
when turning, one of the two front fog lamps is
switched on as a turning lamp. As a result the
inside of the curve is better lighted.
Activating
Switch position
with the ignition switched
on.
The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To avoid blinding oncoming traffic, the Adaptive
Light Control directs light towards the front pas‐
senger side when the vehicle is at a standstill.
When driving in reverse, only the turning lamp is
active.
Malfunction
A Check Control message is displayed.
Adaptive light control is malfunctioning or has
failed. Have the system checked as soon as pos‐
sible.
High-beam Assistant
The concept
When the low beams are switched on, this sys‐
tem 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 sensor on the front of the interior
rearview mirror. The assistant ensures that the
high beams are switched on whenever the traffic
situation allows. The driver can intervene at any
time and switch the high beams on and off as
usual.
Activating
The High-beam Assistant can be activated
when the low beams are switched on.
1.Turn the light switch to or .2.Press the 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 automatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate 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. Depending
on the version of the system in the vehicle, the
high beams may not switch off for oncoming ve‐
hicles, but may only be dimmed in the areas that
blind oncoming traffic. In this case, the blue in‐
dicator light will stay on.

Switching the high beams on and off
manually▷High beams on, arrow 1.▷High beams off/headlamp flasher, arrow 2.
The High-beam Assistant can be switched off
when manually adjusting the light. To reactivate
the High-beam Assistant, press the button on
the turn signal lever.
System limits Personal responsibility
The high-beam assistant cannot serve as
a substitute for the driver's personal judgment
of when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is 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.▷In 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 depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.▷In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Camera
The camera is located near the base of the mir‐
ror.
Keep windshield clean and clear in the area in
front of the interior rear view mirror.
Fog lamps
Front fog lamps
The parking lamps or low beams must be
switched on.
Press the button. The green indicator
lamp lights up.
If the automatic headlamp control, refer to
page 87, is activated, the low beams will come
on automatically when you switch on the front
fog lamps.
Instrument lighting

Working on the lighting system
When working on the lighting system, you
should always switch off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center. Due to the high voltage present
in the system, there is the danger of fatal injuries
if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar, or
hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Light-emitting diodes installed behind a cover
serve as the light source for controls, display el‐
ements and other equipment.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never stare
into the unfiltered light for several hours; other‐
wise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.If the headlamps do not dim despite driving with
the light switched on, increasing humidity forms,
e. g. water droplets in the light, have the service
center check this.
