Adaptive Highbeam Assist PLUS

General notes
With Adaptive Highbeam Assist Plus, you can
automatically switch between low-beam, par-
tial high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of
the high-beam. This prevents glare. When
there is a vehicle in front, for example, the
high-beam headlamps illuminate the areas to
its right and left, and the vehicle in front is
illuminated by the low-beam headlamps.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
If the high-beam or partial high-beam are
causing too much reflection from traffic
signs, the lights are automatically dimmed
and glare for the driver caused by the reflec-
tions is thus avoided.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognize road users:
who have no lights, e.g. pedestrians
R
who have poor lighting, e.g. cyclists
R
whose lighting is blocked, e.g. by a barrier
R
In very rare cases, Adaptive Highbeam Assist
Plus may not recognize road users who do
have lights, or may recognize them too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or will be activated regardless. There is a risk
of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take
into account road, weather or traffic condi-
tions. Adaptive Highbeam Assist Plus is only
an aid. You are responsible for adjusting the
vehicle's lighting to the prevailing light, visi-
bility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
poor visibility, e.g. due to fog, heavy rain or

snow
dirt on the sensors or the sensors are
