High Beam Assist This feature allows the high beam to
function as the main driving light at
night and when vehicle speed is
faster than 25 mph.It switches automatically to low beam
when:
● The camera in the windscreen detects the lights of oncoming or
preceding vehicles.
● The vehicle speed is slower than
12 mph.
● It is foggy or snowy.
● Driving in urban areas.
If there are no restrictions detected,
the system switches back to high

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.
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
