INSTRUMENTS AND CONTROLS

Active main beam*

Active main beam function detects the headlamp
beams from oncoming traffic or the rear lights of
vehicles in front, and switches the lighting from
main beam to dipped beam. The lighting returns
to main beam when the incoming light has stop-
ped.
Active main beam - AHB
Active main beam (Active High Beam - AHB) is a
function which uses a camera sensor at the top
edge of the windscreen to detect the headlamp
beams from oncoming traffic or the rear lights of
vehicles in front, and then switches from main
beam to dipped beam. The function can also take
streetlights into account.
Main beam is reactivated when the camera sen-
sor no longer sees any oncoming vehicles or
vehicles ahead.

minate with main beam on both sides of oncom-
ing traffic or vehicles ahead - only the part of the
light beam that points directly to the vehicle is
dimmed.
Adaptive functionality: Dipped beam directly toward
oncoming vehicles, but continued main beam on both
sides of the vehicle.
