High-beam AssistantThe concept
When the low beams are activated, this system
automatically switches the high beams on and
off. The procedure is controlled by a camera
on the front of the interior rearview mirror. The
assistant ensures that the high beams are acti‐
vated whenever the traffic situation allows. The
driver can intervene at any time and reel the
high beams on and off as usual.

tomatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.

tions where required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.Seite 91LightsControls91
