AHS (Adaptive High-beam System)
● Adjusts the brightness and illuminated area of the high beams
according to the vehicle speed.
● 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 opti-
mize forward visibility while reduc-
ing the dazzling effect on the
drivers of vehicles ahead.
● Adjusts the intensity of the high beams, while driving on a curve, so
that the area in the direction that the vehicle is turning will be illumi-
nated more brightly than other areas.
● Adjusts the distance that the low beams are projected according to
the distance to a preceding vehicle.
The Adaptive High-beam System uses a front camera located
behind the upper portion of the windshield to assess the bright-
ness of the lights of vehicles ahead, streetlights, etc., and auto-
matically controls the headlight light distribution as necessary.
