If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.

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.
