AHS (Adaptive High-beam System)
●
Adjusts the brightness and illuminated area of the high beams according to
the vehicle speed.
● Adjusts the intensity of the high beams, while driving on a curve, so t hat the
area in the direction that the vehicle is turning will be illuminated more brightly
than other areas.
● Operates the variable high beams
so that the area around vehicles
ahead is partially not illuminated
while all other areas continue to be
illuminated with the high beams.
The variable high beams help optimize
forward visibility while reducing the daz-
zling effect on the drivers of vehicles
ahead.
● Adjusts the distance that the low beams are projected according to the dis-
tance to a preceding vehicle.
: If equipped
The Adaptive High-beam System uses a camera sensor located behind the
upper portion of the windshield to assess the brightness of the lights of vehi-
cles ahead, streetlights, etc., and au tomatically controls the headlight light
distribution 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 turning the high beam on or off manually if necessary.
■To prevent incorrect operation of the Adaptive High-beam system
