cases:
= in poor visibility, e.g. fog, heavy rain or snow
= if there is dirt on the sensors or the sensors
are obscured
Adaptive Highbeam Assist Plus is only an aid. You
are responsible for adjusting the vehicle\bs lighting to the prevailing light, visibility and traPc condi-
tions.
Adaptive Highbeam Assist Plus automatically
switches between the following types of light:
= Low beam
= Partial high beam
= High beam
= ULTRA RANGE Highbeam
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
reOective signs are also illuminated with reduced
brightness.
At speeds below 16 mph (25 km/h) or when
there is suPcient street lighting:
= Partial high beam and high beam will be
switched oM automatically.
At speeds greater than 19 mph (30 km/h): = If no other road users are detected, high beam
will switch on automatically.
= If other road users are detected, partial high
beam will switch on automatically.
at speeds below 25 mph (40 km/h):
= The ULTRA RANGE Highbeam will switch oM
automatically.130Light and visibility

= If no other road users are detected, the road is
straight and it is not raining heavily, the ULTRA
RANGE Highbeam will be switched on auto-
matically.
= If other road users are detected, partial high
beam will switch on automatically.
= If highly reOective signs are detected, ULTRA
RANGE Highbeam will be switched oM auto-
matically.\bThe system\bs optical sensor is located behind the windshield near the overhead control
