■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 vehicle 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 beams are projecte d 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 the other vehicles.
■Camera sensor detection information
●The high beams may not be automatically ch anged to the variable high beams in the
following 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 variab le high beams if a vehicle ahead that is
using 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 to
change 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 lights, 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

• 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.
