e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist Plus may fail to recognise other road
users that have lights, or may recognise
them too late.
In this, or in similar situations, the automatic
main beam will not be deactivated or will be
activated despite the presence of other road
users.
Always observe the traffic carefully and
#
switch off the main beam in good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Detection may be restricted in the following
cases:
in poor visibility, e.g. fog, heavy rain or snow
R
if there is dirt on the sensors or the sensors
R
are obscured
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf‐
fic conditions.
The Adaptive Highbeam Assist Plus automati‐
cally switches between the following types of
light:
