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

ness of the cone of light tothe legally permitted
maximum.
Pa rtial high beam does not include other road
users in the high beam area. It does not dazzle
th em but enables full high beam illumination for
th e driver apart from theex cluded vehicles.
At speeds below 25 km/h or when there is su1-
cient street lighting:
R The partial high beam and the high beam will
be switched o. automaticall y.
At speeds greater than 30 km/h:
R If no other road users are de tected, the high
