ULTRA RANGE Highbeam increases the bright-
ness of the cone of light to the legally permitted
maximum.
Partial high beam does not include other road
users in the high beam area. It does not dazzle
them but enables full high-beam illumination for
the driver apart from the excluded vehicles. Highly
reflective signs are also illuminated with reduced
brightness.
At speeds below 25 km/h or when there is suffi-
cient street lighting:
Partial high beam and high beam will be
R
switched off automatically.
At speeds greater than 30 km/h:
If no other road users are detected, high beam
R
will switch on automatically.
If other road users are detected, partial high
R
beam will switch on automatically.
At speeds below 40 km/h:
ULTRA RANGE Highbeam will switch off auto-
R
matically.
At speeds above 50 km/h:
If no other road users are detected, the road is
R
straight and it is not raining heavily, ULTRA
RANGE Highbeam will be switched on auto-
matically.
If other road users are detected, ULTRA
R
RANGE Highbeam will switch off automatically
and the partial high beam will switch on.
If highly reflective signs are detected, ULTRA
R
RANGE Highbeam will be switched off auto-
matically.

& WARNING Risk of accident despite Adap-
tive Highbeam Assist Plus
Adaptive Highbeam Assist Plus does not react
to:
road users without lights, e.g. pedestrians
R
road users with poor lighting, e.g. cyclists
R
road users whose lighting is obstructed,
R
e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist Plus may fail to recognise other road
users with their own lighting, or may recognise
them 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 observe the road and traffic con-
#
ditions carefully and switch off the high
beam in good time.
