Adaptive
Light
Control
Concept
Adaptive Light Control is a variable headlamp 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 114.
Activating
Position of switch:

Adaptive Headlight Control is active when the
engine is running.
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 use
of 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

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 85.
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.

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 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 in the event of an accident despite rej
