142LightingFor deactivation operate the same
procedure as described above.
Control indicator f will not flash when
function is deactivated.
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.
Automatic light control 3 139.
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.With the light switch in position
AUTO all lighting functions are
available.
The following functions are available
also with light switch in position 9:
● dynamic curve lighting
● corner lighting
● reversing function
● dynamic automatic headlight levelling
Playstreet lighting
Activated automatically at low speed
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 rainsensor recognises condensation or
the wiper operates continuously. The
range, distribution and light intensity
is regulated variably depending on visibility.

Lighting143Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Control indicator f 3 115.
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.
Control indicator f 3 115.
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 assist This 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.
Deactivation
Push indicator lever once. It is also
deactivated when front fog lights are
switched on.

144LightingIf 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 disturbing
oncoming 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.
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.
Page 147 of 305

Lighting145Automatic 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 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
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.

Driving and operating203Due to the high position of the
camera, the rear bumper can be seen
on the display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
The function can be deactivated in the
Settings menu in the Info-Display.

certain forward speed is exceeded or
if reverse gear is not engaged for
approx. 10 seconds.
Activation or deactivation of the rear
view camera can be changed in the Settings menu in the Info-Display.

● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
