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 that 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
Do not overload the vehicle.

GS450h_300h_OM_OM30F92E_(EE)
■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 (37 mph) or more.*
*: The area in the direction that the vehicl e is turning will be illuminated more brightly
than other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will turn on and the distance that the low be ams are projected will be adjusted automatically, depending
on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (37 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 variable high beams will be
changed to the low beams automatically:
• The vehicle speed is below approximately 60 km/h (37 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 theother vehicles.
■Camera sensor detection information
●The high beams may not be automatically changed to the variable high beams in thefollowing 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 due 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 variable high beams if a vehicle ahead that isusing fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beams to change to the variable high beams, cause the high beams not tochange to the variable 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 light s, 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.
●Bicycles or similar objects may not be detected.
