To prevent oncoming traffic from being dazzled, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.

Fault in LED headlight system
When the system detects a failure in
the LED headlight system, it selects a preset position to avoid dazzling of
oncoming traffic. A warning is
displayed in the Driver Information Centre.
Hazard warning flashers
Operated by pressing ¨.

If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing
lanes, press the lever until resistance
is felt and then release.
With a trailer connected, turn signal
flashes six times and tone frequency
changes when pressing the lever until resistance is felt and then releasing.
Move the lever to the resistance point
and hold for longer indication.
Switch the turn signal off manually by
moving the lever to its original
position.

174Driving and operatingIn the event of a fault, a warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 122.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
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 the 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 3 110.
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 3 111.
Adaptive brake light During full braking, all three brake
lights flash for the duration of ABS
control.
184Driving and operatingResume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained
and is indicated without brackets in the Driver Information Centre.
Switching off
Press L, the speed limit indication
extinguishes in the Driver Information Centre. The stored speed is deleted.
By pressing m to activate cruise
control or adaptive cruise control,
speed limiter is also deactivated and
the stored speed is deleted.
By switching off the ignition, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Adaptive cruise control
Adaptive cruise control is an
enhancement to conventional cruise
control with the additional feature of
maintaining a certain distance behind the vehicle ahead.Adaptive cruise control automatically
decelerates the vehicle when
approaching a slower moving vehicle. It then adjusts the vehicle speed to
follow the vehicle ahead at the
selected following distance. The
vehicle speed increases or decreases to follow the vehicle in front, but willnot exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store
and maintain speeds over approx.
25 km/h. If following a vehicle ahead
driving slower than 25 km/h, the
slower speed will be set. On vehicles
with automatic transmission, the
system can also brake to a stop.
Adaptive cruise control uses a radar
sensor to detect the vehicles ahead.
If no vehicle is detected in the driving
path, the adaptive cruise control will
behave like a conventional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal or clutch pedal has been
depressed once since switching on
ignition.
Adaptive cruise control is mainly
advised to be used on long straight
roads like highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
Control indicator A 3 113, m 3 113,
C 3 113.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the cancel
switch have priority over any
adaptive cruise control operation.
