ness, for instance in tunnels, in twilight or if there is precipitation.
General
information
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
When emerging from a tunnel during the day,
the low beams are not switched off immedij
ately but instead only after approx. 2 minutes.
The low beams always stay on when the fog

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
Control The
conceptAdaptive Light Control is a variable headlight
control system that enables dynamic illuminaj
tion of the road surface.
General
information
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 drivj er's side when the vehicle is at a standstill.
Depending on the equipment version, Adapj
tive Light Control consists of one or several systems:'yCornering light, refer to page 102.
Activating
Position of switch

Cornering
light
In tight curves, for instance on mountainous
roads or when turning, a cornering light is switched on up to a certain speed. As a resultthe inside of the curve is better lighted.
The cornering light is automatically switched
on depending on the steering angle or the use
of turn signals.
When driving in reverse, the cornering 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 immediately checked
by a dealerss service center or another qualij
fied service center or repair shop.
Self-leveling
headlights
The self-leveling headlights compensate for
acceleration and braking operations in order not to blind the oncoming traffic and to achieveoptimum 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. The assistant ensures
that the high beams are switched on, whenj
ever the traffic situation allows. In the low
speed range, the high beams are not switched
on by the system.
General
information
The system responds to light from oncoming traffic and traffic driving ahead of you, and toadequate illumination, for instance in townsand cities.
The high beams can be switched on and off at any time as usual.
Activating/deactivating1.Depending on the equipment, turn the light switch into position
or .
2.Press button on the turn signal lever, arjrow.
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 74. 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. Therefore, manj
ually switch off the high beams in situations
where required to avoid a safety risk.
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.

SafetyVehicle
features
and
options
This chapter describes all standard, country- specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., dueto the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable laws and regulations
must be observed.
Airbags

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, e.g., in less severe accidents or rear-end collisions.
Information
on
optimum
effect
of
theairbags
WARNING
If the seat position is incorrect or the dej
ployment area of the airbags is impaired, the airbag system cannot provide protection as injtended and may cause additional injuries dueto triggering. There is a risk of injuries or danjger to life. Follow the information on 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 in the event of an accident despite rej
spective accident severity. There is a risk of injuries or danger to life. Have the airbag sysj
tem checked, repaired, dismantled and scrapj ped by a dealerss service center or anotherqualified service center or repair shop.'

Indicator
lamp
for
the
front-seat
passenger
airbags
The indicator lamp for the front-seat passenj ger airbags indicates the operating state of thefront-seat passenger airbags.
The lamp indicates whether the airbags are eij
ther activated or deactivated.
'yThe indicator lamp lights up
when a child is properly
seated in a child restraint fixj
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.'yThe indicator lamp does not light up when, e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags
on the front passenger side are activated.
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 passenger's airbags very much depends
on the positions of the driver's/front passengj er's 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 property damage. Make sure that the area ofmovement of the seat is clear prior to any adjjustment.'

General
information
With use of the system observe further inforj mation found under Tire inflation pressure, rej
fer to page 202.
Functional
requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, reliaj ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
