Adaptive Highbeam Assist
Depending on the driving and traffic situation,
low-beam leveling and the high-beam
headlamps are controlled via an optical
sensor. The sensor is located on the front of
the overhead control panel. Glare for other
road users is reduced and the illumination of
road ahead is improved. The transitions
between low-beam and high-beam
headlamps take place without a sudden
change of light.
GWarning!
The Adaptive Highbeam Assist is only an aid
intended to support you while driving. The
driver is and remains responsible for proper
vehicle lighting in accordance with the
prevailing light, sight and traffic conditions.
The system may be impaired or unavailable
