Main beam assist
Applies to: vehicles with main beam assist
The main beam assist automatically switches
the main beam headlights on or off depending
on the surrounding Light conditions.
Fig. 39
Turn signal and main beam lever: Switching main
beam assist on/off
A camera (located in the mounting for the interi
or mirror) detects light sources from other road
users. The main beams are activated or deactiva
ted automatically depending on the position of
vehicles on either side of the road, on the road
speed, and on other traffic and ambient condi
tions.
On vehicles with matrix LED headlights, individu
al segments of the main beam are activated or
deactivated. The relevant sector in front of the
vehicle is masked, while the surrounding areas
remain lit. The ambient surroundings are thus il
luminated optimally without dazzling other road
users.
