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.
