Rain sensor
The concept
The time between wipes is controlled automat‐
ically and depends on the intensity of the rainfall.
The sensor is located on the windshield, directly
in front of the interior rearview mirror.
Activating/deactivating the rain sensor
Press the button on the wiper lever.
When activated, the wipers move over the wind‐
shield once.
The LED in the steering column stalk lights up.
Deactivate the rain sensor in car washes
Deactivate the rain sensor when passing
through an automatic car wash; otherwise, dam‐
age could be caused by undesired wiper activa‐
tion.◀
Rain sensor sensitivity
Turn the thumbwheel.
Clean the windshield, headlamps
Pull the lever.
The system sprays washer fluid on the wind‐
shield and activates the wipers briefly.
In addition, the headlamps are cleaned at regular
intervals when the vehicle lights are switched
on.
Do not use the washer system at freezing
temperatures
Do not use the washers if there is any danger
that the fluid will freeze on the windshield; oth‐
erwise, your vision could be obscured. For this
reason, use antifreeze.
Avoid using the washer when the reservoir is
empty; otherwise, you could damage the
pump.◀
Windshield washer nozzles
The washer jets are automatically heated when‐
ever the ignition is switched on.
Fold-out position of the wipers
Required when changing the wiper blades or
under frosty conditions, for example.
1.Switch off the ignition.2.Under frosty conditions, ensure that the
wiper blades are not frozen onto the wind‐
shield.3.Press the wiper lever up beyond the point of
resistance and hold it for approx. 3 seconds,
until the wiper remains in a nearly vertical
position.Seite 65DrivingControls65

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 82.

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, 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.
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.
Self-leveling headlights
The self-leveling headlights feature adapts the
light distribution to the contours of the road.
The light distribution is lowered on hilltops to
avoid blinding oncoming traffic and tilted in de‐
pressions to increase visibility.
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. The procedure is controlled 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 al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.
Activating1.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 lights are switched on, the
high beams are switched on and off automati‐
cally.
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.

Switching the high beams on and off
manually▷High beams on, arrow 1.▷High beams off/headlamp flasher, arrow 2.
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 82, is activated, the low beams will come
on automatically when you switch on the front
fog lamps.
Instrument lighting
Adjusting The parking lamps or low beams
must be switched on to adjust the
brightness.
Adjust the brightness using the
thumbwheel.

Press the button.▷On: the LED lights up.▷Off: the LED goes out.
The system can issue warnings at speeds above
approx. 40 mph/65 km/h.
The state is stored for the remote control cur‐
rently in use.
Display
▷Lines, arrow 1: the system is activated.▷Arrows, arrow 2: at least one lane marking
was detected and warnings can be issued.
Issued warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vi‐
brating.
If the turn signal is set before changing the lane,
a warning is not issued.
End of warning
The warning ends:
▷Automatically after approx. 3 seconds.▷When returning to your own lane.▷When braking hard.▷When using the turn signal.System limits
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the course
of the road and the traffic situation.
In the event of a warning, do not jerk the steering
wheel, as you may lose control of the vehicle.◀
The system may not be fully functional in the
following situations:▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merging,
diverging, or multiple lane markings such as
in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by ob‐
jects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Malfunctions
Steering wheel vibration
Frequent activation of the steering wheel vibra‐
tion causes the system to overheat.
This causes the lane departure warning to be‐
come deactivated.
Let the system cool and reactivate it by pressing
the button.

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.
Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper mon‐
itor the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehicles
in the blind spot, arrow 1, or approaching from
behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights up
dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the situa‐
tions described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Switching on/off
Press the button.
▷On: the LED lights up.▷Off: the LED goes out.
The system can issue warnings at speeds above
approx. 30 mph/50 km/h.
The state is stored for the remote control cur‐
rently in use.
Display
Information stage
The dimmed lamp in the mirror housing indi‐
cates when there are vehicles in the blind spot
or approaching from behind.
Warning
If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the mirror housing flashes
brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the crit‐
ical zone.
