High-beam AssistantThe concept
The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are activated whenever
the traffic situation allows. In the low speed
range, the high beams are not switched on by
the system.
General information
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 driver can intervene at any time and switch
the high beams on and off as usual.
Depending on the version of the system in the
vehicle, the high beams may not switch off for
oncoming vehicles, but may only be dimmed in
the areas that blind oncoming traffic. In this
case, the blue indicator light will stay on.
Activating1.Turn the light switch to position .2.Press and hold PC button on blinker lever.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.
Deactivating The High-beam Assistant can be switched off
when manually switching the high beams on
and off, refer to page 103. To reactivate the
High-beam Assistant, press the button on the
turn signal lever.
System limits The High-beam Assistant cannot serve as a
substitute for the driver's personal judgment of
when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where required to avoid a safety risk.
The system is not fully functional in the follow‐
ing situations, 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; or at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on highways.▷In poorly-lit towns and cities or in the pres‐
ence of highly reflective signs.▷When the windshield behind the interior
mirror is fogged over, dirty or covered with
stickers, etc.
