Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated 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 cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. You areresponsible for adjusting the vehicle's lightingto the prevailing light, visibility and traffic con-ditions.
In particular, the detection of obstacles can beimpaired if:
Rthere is poor visibility, e.g. due to fog, heavyrain or snow
Rthere is dirt on the sensors or anything elsecovering the sensors
