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.
Page 146 of 307

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 307

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.
Page 148 of 307

146LightingFor three flashes, e.g. when changing
lanes, press the lever until resistance is felt and then release.
When a trailer is connected, turn
signal flashes six times 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.
Front fog lights
Operated by pressing >.
Light switch in position AUTO:
switching on front fog lights will switch headlights on automatically.
Rear fog light
Operated by pressing r
.
Light switch in position AUTO:
switching on rear fog light will switch
headlights on automatically.
Light switch in position 8: rear fog
light can only be switched on with
front fog lights.
The vehicle rear fog light is
deactivated when towing.
Parking lights
When the vehicle is parked, the
parking lights on one side can be
activated:
1. Switch off ignition.
2. Move turn signal lever all the way up (right parking lights) or down
(left parking lights).
Confirmed by a signal and the
corresponding turn signal control
indicator.
