System
limits
The automatic headlight control cannot serve
as a substitute for your personal judgment of
lighting conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks unj
der these conditions, you should always switch
on the lights manually.

Adaptive
light
functions
Concept
Adaptive light functions enable dynamic illumij
nation of the roadway.
General
information
The adaptive light functions may consist of
one system or multiple systems, depending on
the equipment version:'yAdaptive Light Control, refer to page 123.'yCornering light, refer to page 123.
Activating
Position of switch:

The adaptive light functions are active when
the engine is running.
Adaptive
Light
Control Depending on the steering angle and other paj
rameters, the light from the headlight follows the course of the road.
To avoid blinding oncoming traffic, the Adapj
tive Light Control does not swivel to the oppoj
site lane when the vehicle is at a standstill.
Cornering
light
In tight curves, for instance on mountainous
roads or when turning, an additional, cornering light is switched on that lights up the inside of
the curve better when the vehicle is moving
below a certain speed.
The cornering light is automatically switched on depending on the steering angle or the useof turn signals.
When driving in reverse, the cornering lights
may be automatically switched on regardless of the steering angle.
Adaptive
headlight
range
control
The adaptive headlight range control compenj
sates for acceleration and braking operations
in order not to blind the oncoming traffic and to
achieve optimum illumination of the roadway.

High-beam
AssistantConcept
The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation.
General
information
The high-beam Assistant ensures that the high beams are switched on, whenever the traffic
situation allows. In the low speed range, the high beams are not switched on by the system.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, for instance in towns
and cities.
The high beams can be switched on and off at
any time as usual.
Activating/deactivating
Position of switch, depending on the vehicle
equipment:
,
Press and hold button on signal lever.
The indicator light in the instrument
cluster is illuminated when the low
beams are switched on.
The headlights are automatically switched bej tween low beams and high beams.
The blue indicator light in the instruj
ment cluster lights up when the system
switches on the high beams.
The high-beam Assistant is deactivated when manually switching the high beams on and off,
refer to page 93.
To reactivate the high-beam Assistant, press the button on the turn signal lever.
System
limits
The high-beam Assistant cannot serve as a substitute for the driver's personal judgment of
when to use the high beams. In situation that require this, therefore switch off manually.
The system is not fully functional in the followj ing situations, and driver intervention may be
necessary:'yIn very unfavorable weather conditions,
such as fog or heavy precipitation.'yWhen 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.'yIn tight curves, on hilltops or in depresj
sions, in cross traffic or half-obscured onj coming traffic on highways.'yIn poorly-lit towns and cities and in thepresence of highly reflective signs.'yWhen the windshield in front of the interior
mirror is fogged over, dirty or covered with stickers, etc.

airbags
Front airbags help protect the driver and the front passenger by responding to frontal imj
pacts in which safety belts alone would not
provide adequate protection.Side

In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.

Ejection
MitigationThe head airbag system is designed as anejection mitigation countermeasure to reducethe likelihood of ejections of vehicle occupantsthrough side windows during rollovers or sideimpact events.
Knee
airbag The knee airbag supports the legs in a frontal
impact.
Protective
action
Airbags are not triggered in every impact situaj
tion, for instance in less severe accidents or rear-end collisions.
Information
on
optimum
effect
of
the
airbags
WARNING
If the seat position is incorrect or the dej
ployment area of the airbags is impaired, the airbag system cannot provide protection as inj
tended and may cause additional injuries due to triggering. There is a risk of injuries or danj
ger to life. Follow the information on achieving
the optimum protective effect of the airbag system.'

WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering of the airbag system. In the case of a malfuncj
tion, the airbag system might not trigger as inj
tended despite the accident severity. There is
a risk of injuries or danger to life. Have the airj bag system checked, repaired, dismantled andscrapped by a dealerss service center or anjother qualified service center or repair shop.'

Indicator
light
for
the
front-seat
passenger
airbags
The indicator light for the front-seat passenger airbags indicates the operating state of the
front-seat passenger airbags.
The light indicates whether the airbags are eij
ther activated or deactivated.
'yThe indicator light lights up
when a child is properly
seated in a child restraint
system or when the seat is
empty. The airbags on the
front passenger side are not
activated.'yThe indicator light does not light up when,
for instance a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are acj
tivated.
Detected
child
restraint
systems
The system generally detects children seated in a child restraint system, particularly in child
restraint systems required by NHTSA at the
point in time when the vehicle was manufacj
tured. After installing a child restraint system,
make sure that the indicator light for the front-
seat passenger airbags lights up. This indij
cates that the child restraint system has been detected and the front-seat passenger airbags
are not activated.
Strength
of
the
driver's
and
front-seat
passenger
airbag
The explosive power that activates driver's/front-seat passenger airbags very much dej
pends on the positions of the driver's/front
passenger seat.
To maintain the accuracy of this function over the long term, calibrate the front seats as soon
as a respective message appears on the Conj
trol Display.
Calibrating
the
front
seats WARNING
There is a risk of jamming when moving
the seats. There is a risk of injury or risk of damage to property. Make sure that the area ofmovement of the seat is clear prior to any adjjustment.'
