cally switches between the following types of

ULTRA RANGE Highbeam increases the bright‐
ness of the cone of light to the legally permitted
maximum.

past other road users rather than dazzling them.
The vehicle in front is illuminated by the low
beam.
At speeds below 25 km/h or when there is suffi‐
cient street lighting:
The partial high beam and the high beam

R
beam is switched on automatically.
If other road users are detected, the partial
R
high beam is switched on automatically.
At speeds above 40 km/h:
If no other road users are detected on a
R
straight road, ULTRA RANGE Highbeam is
switched on automatically.
If other road users are detected, the partial
R
high beam is switched on automatically.
