Important safety notes
G WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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 recognise road users who do
have lights, or may recognise them too late. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the main-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
R
snow
dirt on the sensors or if the sensors are
R
obscured
