AHS (Adaptive High-beam System)

● When the variable beams are on, the
area around oncoming vehicles and
preceding vehicles is partially not
illuminated while all other areas con-
tinue to be illuminated with the high
beams. This enables forward lighting
to be optimized without blinding
drivers in surrounding vehicles.
● When the high beams are on, their brightness and area that they illuminate will
change according to the vehicle speed.
● When the low beams are on, the distance that they are projected will change
according to the distance to a preceding vehicle.
: If equipped
The Adaptive High-beam System uses the camera sensor located behind the
windshield to assess the brightness of the lights of vehicles ahead, streetlights,
etc., and automatically turns the high beams, low beams, and variable beams
of the headlights on or off as necessary.
WARNING
■ Limitations of the Adaptive High-beam System
Do not rely on the Adaptive High-beam System. Always drive safely, taking care to
observe your surroundings and turn the high beam on or off manually if necessary.
■ To prevent incorrect operation of the Adaptive High-beam system
Do not overload the vehicle.
