Headlights when driving
abroad The asymmetrical headlight beam
extends visibility at the edge of the
road at the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights to prevent dazzling of oncoming
traffic.

Daytime running lights
Daytime running light increases
visibility of the vehicle during daylight.
They are switched on automatically
when ignition is on.
If the vehicle is equipped with
automatic light control function, the
system switches between daytime running light and low/high beam
automatically depending on the
lighting conditions and information
given by the rain sensor system.

Adaptive forward lighting
The Adaptive forward lighting
functions are only available with Bi-
Xenon headlights. Light range, light
distribution and intensity of light are
variably triggered depending on the
light conditions, weather and road
type.

up to approx. 20 mph. The light beam
is turned at an angle of 8° to the
roadside.
Town lighting Activated automatically at a speed
range between approx. 25 and
34 mph and when street lights are
detected by the light sensor. The light
range is reduced by an extended light
distribution.Country lighting
Activated automatically at a speed
range between approx. 34 and
70 mph. The beam of light and the
brightness is different between the left and the right side.
Motorway lighting
Activated automatically at a speed
above approx. 70 mph and minimal
steering movements. It switches on
after a delay or directly when the
vehicle is powerfully accelerated. The
light beam is longer and brighter.
Adverse weather lighting Activated automatically up to a speed
of approx. 43 mph, when the rain sensor recognises condensation or
the wiper operates continuously. The
range, distribution and light intensity
is regulated variably depending on
visibility.Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Control indicator f 3 116.
Corner lighting
On tight bends or when turning off,
depending on the steering angle or
the turn signal light, an additional left
or right reflector is switched on which illuminates the road at an right angle
to the direction of travel. It is activated
up to a speed of 25 mph.

Reversing function
If the headlights are on and reverse
gear is engaged, both corner lights
are switched on. They remain
illuminated for 20 seconds after
disengaging reverse gear or until
driving faster than 10 mph in a
forward gear.
High beam assistThis feature allows high beam as
main driving light by night and when
vehicle speed is faster than 25 mph.
It switches to low beam when: ■ The camera in the windscreen detects the lights of oncoming or
preceding vehicles.
■ The vehicle speed is slower than 12 mph.
■ It is foggy or snowy.
■ Driving in urban areas.
If there are no restrictions detected,
the system switches back to high
beam.Activation
The high beam assist is activated by
pushing the indicator lever twice with
a speed above 25 mph.
The green control indicator l
illuminates continuously when the
assist is activated, the blue one 7
illuminates when high beam is on.
Control indicator l 3 115.

Push indicator lever once. It is also
deactivated when front fog lights are
switched on.
If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.
If a headlight flash is activated when
the high beam is off, the high beam
assist will stay activated.
High beam assist is always active
after the ignition is switched on.
Intelligent light ranging with automatic high beam activation Intelligent light ranging uses the
properties of Bi-Xenon headlights to
extend the light range of the low
beams by up to 400 metres and
additionally activates automatic high beam without dazzling or disturbingoncoming or preceding traffic.
High beam is deactivated and the low
beam light range will be reduced to
avoid dazzling when the following
restrictions are detected by the front
camera in the windscreen:
■ A preceding vehicle is recognised.
■ An oncoming vehicle is recognised.
■ Urban areas are entered.
■ Iit is foggy or snowy.
Lighting141
If there are no restrictions detected,
the system switches back to high
beam.
When the system is active, the front
camera monitors the area ahead of
the vehicle and ensures an optimum
light distribution for maximum driver
vision during almost all conditions
Intelligent light ranging with automatic
high beam activation therefore
reduces the difference between
conventional low and high beam
without drastic changes in light-
range, distribution and intensity.A special topographical evaluation
function detects preceding vehicles
on hills or slopes by recognising the
rear light moving ahead. The system
adjusts the height of the light range to
ensure optimum illumination on the
road ahead without dazzling.
Activation
Intelligent light ranging and automatic
high beam activation are switched on together by pushing the indicator
lever twice. They can be switched on
with ignition on.
Automatic high beam activation
operates at a speed above 25 mph
and deactivates below 12 mph.
Intelligent light ranging operates
above 35 mph.
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 headlight
levelling
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.
142Lighting
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.

Driving and operating179
The limited speed will flash in the
Driver Information Centre and a
chime sounds during this period.
Release the accelerator pedal and the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation
Press y: speed limiter is deactivated
and the vehicle can be driven without
speed limit.
The limited speed is stored and a
corresponding message appears in
the Driver Information Centre.
Resume limit speed
Turn thumb wheel to RES/+. The
stored speed limit will be obtained.
Switching off
Press L, the speed limit indication in
the Driver Information Centre extinguishes. The stored speed is
deleted.By pressing m to activate cruise
control or adaptive cruise control or
by switching off the ignition, speed limiter is also deactivated and the
stored speed is deleted.
Adaptive cruise control
Adaptive cruise control is an
enhancement to traditional 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 will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
The adaptive cruise control can store and maintain speeds over approx.
30 mph and brakes automatically tofollow a slower vehicle driving ahead
down to a minimum speed of
18 mph.
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 traditional cruise
control.
For safety reasons, the system
cannot be activated before the brake
pedal has been depressed once after
switching on ignition. Activation in first gear is not possible.
Adaptive cruise control is mainly
advised to be used on long straight
roads, e.g. highways or country roads
with steady traffic. Do not use the
system if it is not advisable to
maintain a constant speed.
