Control indicator 8 3 92.

Lighting123Automatic high beam activation
operates at a speed above 40 km/h
and deactivates below 20 km/h.
Intelligent light ranging operates
above 55 km/h.
The green control indicator l
illuminates continuously when the
function is activated, the blue one 7
illuminates when high beam switches
on automatically.
Deactivation
Push indicator lever once. It is also deactivated when front fog lights are
switched on.
Dynamic automatic headlightlevelling
To prevent oncoming traffic from
dazzle, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.Fault in adaptive forward lighting
system
When the system detects a failure in
the Adaptive forward lighting system,
the system moves to a preset position to avoid dazzling of oncoming traffic.
If this is not possible the affected
headlight will be automatically
switched off. In any case one
headlight will stay on. A warning is
displayed in the Driver Information
Centre.
Hazard warning flashers
Operated by pressing ¨.
In the event of an accident with airbag
deployment the hazard warning
flashers are activated automatically.
Turn and lane-changesignalslever up:right turn signallever down:left turn signal
A resistance point can be felt when
moving the lever.
Constant flashing is activated when
the lever is being moved beyond the
resistance point. It is deactivated
when the steering wheel is moved in

152Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 88.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.
Control indicator u 3 89.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.

Vehicle care201End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website, where legally required. Only
entrust this work to an authorised
recycling centre.
Gas vehicles must be recycled by a
service centre authorised for gas
vehicles.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
Bonnet
Opening
Pull the release lever and return it to
its original position.
