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 3 116.
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
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,
■ 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.
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 from dazzle, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.

headlight will stay on. A warning is
displayed in the Driver Information Centre.
