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.
Vehicles with halogen headlight
system
The headlights do not have to be adjusted.Vehicles with Xenon headlight
system
1. Key in ignition switch.
2. Pull turn signal lever and hold (headlight flash).
3. Switch on ignition.
4. After approx. five seconds the control indicator f starts flashing
and an acoustic signal sounds.
Control indicator f 3 92.
Every time the ignition is switched on,
f flashes as a reminder for approx.
four seconds.

120LightingFor deactivation, operate the same
procedure as described above. f will
not flash when function is deactivated.
Daytime running lights
Daytime running lights increase
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 3 117.
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
● cornering light
● reversing function
● dynamic automatic headlight levelling
Playstreet lighting
Activated automatically at low speed
up to approx. 30 km/h. The light beam is turned at an angle of 8° to the
roadside.
Town lighting
Activated automatically at a speed
range between approx. 40 and
55 km/h 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. 55 and
115 km/h. 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. 115 km/h 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. 70 km/h, when the rain
sensor recognizes condensation or
the wiper operates continuously. The
range, distribution and light intensity
is regulated variably depending on visibility.

Lighting121Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Control indicator f 3 92.
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 a right angle to
the direction of travel. It is activated
up to a speed of 40 km/h.
Control indicator f 3 92.
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 17 km/h 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 40 km/h.
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
20 km/h.
● 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 40 km/h.
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 92.
Deactivation
Push indicator lever once. It is also
deactivated when front fog lights are
switched on.
Page 124 of 295

122LightingIf 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 beam 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 is 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.
● It 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 125 of 295

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.
