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.

■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.

●In the situations shown below, the system may not be able to accurately detect sur- rounding brightness levels. This may cause the low beams to remain on or the highbeams to cause problems for pedestrians, vehicles ahead or other parties. In these
cases, manually switch between the high and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.) • The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged. • The camera sensor is deformed or dirty.• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to th ose of headlights, tail lights or fog lights. • Vehicles ahead have headlights that are either switched off, dirty, are changing color,or are not aimed properly.
• The vehicle is hit by water, snow, dust, etc. from a preceding vehicle. • When driving through an area of interm ittently changing brightness and darkness. • When frequently and repeatedly driving ascending/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.). • When frequently and repeatedly taking curves or driving on a winding road.• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck. • The vehicle’s headlights are damaged or dirty.• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeated ly being switched between in an abnor- mal manner.• The driver believes that the high beam may be causing problems or distress to other
drivers or pedestrians nearby.
■Warning message
Warning messages are used to indicate a syst em malfunction or to inform the driver of
the need for caution. ( P. 466)
■Customization
Some functions can be customized. ( P. 561)

■High beam automatic turning on or off conditions
●When all of the following conditions are fulfilled, the high beam will be automatically turned on (after approximately 1 second):
• Vehicle speed is above approximately 40 km/h (25 mph).
• The area ahead of the vehicle is dark. • There are no vehicles ahead with headlights or tail lights turned on.• There are few streetlights on the road ahead.
