Automatic light control

When the automatic light control
function is switched on and the
engine is running, the system
switches between daytime running
lights and headlights automatically
depending on the external lighting
conditions and information given by
the rain sensor system.
Daytime running light 3 133.
Automatic headlight activation
During poor lighting conditions
headlights are switched on.
Additionally, headlights are switched
on if the windscreen wipers have
been activated for several wipes.
LED headlights 3 133.
Tunnel detection
When a tunnel is entered headlights
are switched on immediately.

High beam assist

The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Once activated,
high beam assist remains active and
switches high beam on and off
automatically. The latest setting of the
high beam assist will remain after the
ignition is switched on again.
It switches automatically to low beam
when:
● Driving in urban areas.
● It is foggy or snowy.
● Fog lights are switched on.
If there are no restrictions detected,
the system switches back to high
beam.
This feature allows the high beam to
function as main driving light at night.
Each LED on right or left side is
triggered or faded out particularly
according to the traffic situation. This
gives the best light distribution
without dazzling other road users.
High beam is switched on
automatically at a speed above
31 mph. High beam is switched off at
a speed below 22 mph, but high beam
assist remains active.
