●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 that the
area in the direction that the vehicle is turning will be illuminated more brightly
than other areas.
●Operates the shaded high beams so
that the area around vehicles ahead
is partially not illuminated while all
other areas continue to be illumi-
nated with the high beams.
The shaded 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.
AHS (Adaptive High-beam System)
: 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 automatically controls the headlight light
distribution as necessary.
WARNING
■Limitations of the Adaptive High-beam System
Do not overly rely on the Adaptive High-b eam System. Always drive safely, taking care to observe your surroundings and turning the high beams on or off manually if neces- sary.
■To prevent incorrect operation of the Adaptive High-beam System
Do not overload the vehicle.

■Conditions in which the light distribution control of the headlights changes automati-
cally
●When all of the following conditions are met, the high beams will be turned on automat- ically and the system will operate:
• The vehicle speed is approximately 60 km/h (38 mph) or more. • The area ahead of the vehicle is dark.
●When all of the following conditions are me t, the shaded high beams will turn on and the distance that the low beams are projecte d will be adjusted automatically, depending on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (38 mph) or more. • The area ahead of the vehicle is dark.• There are vehicles ahead with headlights or tail lights turned on.
●If any of the following conditions is met, the high beams or shaded high beams will be changed to the low beams automatically:
• The vehicle speed is below approximately 60 km/h (38 mph). • The area ahead of the vehicle is not dark.• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the drivers of the other vehicles.
■Camera sensor detection information
●The high beams may not be automatically changed to the shaded high beams in the fol-lowing situations:
• When vehicles ahead suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle • When vehicles ahead are hidden from sight du e to repeated curves, road dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road • When vehicles ahead have no lights
●The high beams may be changed to the shad ed high beams if a vehicle ahead that is using fog lights without its head lights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs and other
reflective objects may cause the high beam s to change to the shaded high beams, cause the high beams not to change to the sh aded high beams, or change the area that is not illuminated.
●The following factors may affect the amount of time taken to turn the high beam on or off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog lig hts, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead • When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle • The condition of the road (gradient, curve, condition of the road surface etc.)• The number of passengers and amount of luggage
●The light distribution control of the headlights may change unexpectedly.
