is displayed in percent in the Driver
Information Centre.
Reset Press SET/CLR on turn signal lever
for several seconds to reset. The
remaining engine oil life duration
page must be active. Switch on
ignition, but not the engine.
The system must be reset every time
the engine oil is changed, to ensure
proper functionality. Seek the
assistance of a workshop.

High beam assist
Description for version with halogen
headlights. High beam assist with
adaptive forward lighting 3 117.
This feature allows high beam to
function as the main driving light at
night and when vehicle speed is
faster than 40 km/h.
It switches to low beam when: ● A sensor 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 at 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 94.
Deactivation Push indicator lever once. It is also
deactivated when front fog lights are
switched on.
Lighting119Activation
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 94.
Deactivation
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 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.
120LightingA 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 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 headlight
levelling
To prevent oncoming traffic fromdazzle, 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.
