2021 MERCEDES-BENZ V-CLASS sensor

The system de
tects that vehicle lights are
approaching in the opposite direction or driving
ahead of theve hicle.
If yo ur speed is greater than 30 km/h and no other
ro ad users are de tected, high beam will automati-
cally be switched on.
If yo ur speed is greater than 25 km/h, the head-
lamp range will be controlled automatically
depending on the distance from other road users.
High beam will automatically be deacti vated in the
fo llowing cases:
R Your speed is lo werth an 25 km/h.
R Other road users ha vebeen de tected.
R The road is su1ciently illuminated.

WARNING
ARNING Risk of accident despite Adap-
tive Highbeam Assist Plus
Ad aptive Highbeam Assist Plus does not react
to:
R road users without lights, e.g. pedestrians
R road users with poor lighting, e.g. cyclists
R road users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist Plus may failto recognise other road
users with their own lighting, or may recognise
th em too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or will be
activated despite the presence of other road
users. #
Always obser vethero ad and tra1c con-
ditions carefully and switch o. the high
beam in good time. Ad
aptive Highbeam Assist Plus cann ottake into
account road, weather or tra1c conditions.
De tection may be restric ted in thefo llowing cases:
R In poor visibility, e.g. fog, heavy rain or snow
R ifth ere is dirt on the sensors or the sensors
are obscured
Ad aptive Highbeam Assist Plus is only an aid. Yo u
are responsible for ensuring cor rect vehicle light-
ing in accordance with the pr evailing light, visibility
and tra1c conditions. Light and vision

Ad
aptive Highbeam Assist Plus switches automati-
cally between thefo llowing light types:
R Low beam
R Partial high beam
R High beam
Pa rtial high beam uses high beam toshine past
ot her road users rather than dazzling them. The
low beam illumination area co vers theve hicle in
front.
At speeds lo werth an 25 km/h or if there is insu1-
cient street lighting, Highbeam Assist Plus will per-
fo rm thefo llowing actions:
R Partial high beam and high beam will be auto-
matically deactivated.
R The K indicator lamp on the inst rument
cluster will go out. The _symbol for High-
beam Assist Plus will remain switched on.
At speeds greater than 30 km/h, Highbeam Assist
Plus will per form thefo llowing actions:
R If no other road users are de tected, high beam
will be switched on.
R Ifot her road users are de tected, partial high
beam will be switched on.
R The K indicator lamp on the inst rument
cluster will light up.
At speeds greater than 40 km/h, Highbeam Assist
Plus will per form thefo llowing actions:
R If no other road users are de tected and the
ro ad is st raight, high beam will be switched on.
R If highly re0ective signs are de tected, high
beam will automatically be switched o..
