■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.

●Bicycles or similar objects may not be detected.
●In the following situations the system may not be able to correctly detect the surround- ing brightness level. This may cause the low beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc. • When the windshield is cracked or damaged• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high • When the surrounding brightness level is equa l to that of headlights, tail lights or fog lights
• When headlights or tail lights of vehicles ah ead are turned off, dirty, changing color, or not aimed properly• When 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 withrough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)
• When frequently and repeatedly taking curves or driving on a winding road • When there is a highly reflective object ahead of the vehicle, such as a sign or mirror• When the back of a preceding vehicle is highly reflective, such as a container on a
truck • When the vehicle’s headlights are damaged or dirty, or are not aimed properly• When the vehicle is listing or tilting due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams repeat- edly in an abnormal manner• When the driver believes that the high beams may be flashing or dazzling pedestri-
ans or other drivers • When the vehicle is used in an area in which vehicles travel on the opposite side of
the road of the country for which the vehicle was designed, for example using a vehi- cle designed for right-hand traffic in a left-hand traffic area, or vice versa
