WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
if there is poor visibility, e.g. due to snow,
R
rain, fog or spray
if the area of the windscreen around the
R
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
road users that have no lighting, e.g. pedes-
R
trians
road users that have poor lighting, e.g.
R
cyclists
road users whose lighting is not clearly visi-
R
ble, e.g. road users behind a crash barrier
on rare occasions: road users that have
R
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually.
