LIGHTING
Active main beam
Active main beam is a function which uses a
camera sensor at the top edge of the wind-
screen 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 symbol represents active main beam.
The function can start while driving in the dark
when the car's speed is approx. 20 km/h (approx.
12 mph) or higher. The function can also take
streetlights into account. When the camera sen-
sor no longer detects any oncoming car or car in
front, main beam is switched on again after about
a second.
