■Daytime running light system
To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenev er the engine is started and the parking
brake is released with the headlight switch in position. (Illuminate brighter than
the front position lights.) Daytime running lights are not designed for use at night.
■Cornering lights (if equipped)
When the cornering lights are on for more than 30 minutes, they will turn off automati-
cally.
■Headlight control sensor
■Automatic light off system
●When the light switch is in the or position: The headlights and front fog
lights turn off automatically if the engine switch is turned to ACCESSORY mode or off.
●When the light switch is in the position: The headlights and all lights turn off auto-
matically if the engine switch is turned to ACCESSORY mode or off.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch to the
position once and then back to the or position.
■Automatic headlight leveling system
The level of the headlights is automatically ad justed according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Light reminder buzzer
A buzzer sounds when the engine switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■Welcome lighting
If the headlight switch is turned to and the surrounding area is dark, unlocking the
doors using the smart entry & start system or wireless remote control will turn the front
position lights and tail lights on automatically.
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

■Windshield wiper linked headlight illumination
When driving during daytime with the headlig ht switch turned to , if the windshield
wipers are used, the headlights will turn on automatically after several seconds to help
enhance the visibility of your vehicle.
■Battery-saving function
In order to prevent the battery of the vehicle fr om discharging, if the light switch is in the
or position when the engine switch is turned off the battery saving function
will operate and automatically turn off all the lights after approximately 20 minutes.
When the engine switch is turned to IGNITION ON mode, the battery-saving function
will be disabled.
When any of the following are performed, the battery-saving function is canceled once
and then reactivated. All the lights will turn off automatically 20 minutes after the bat-
tery-saving function has been reactivated:
●When the headlight switch is operated
●When a door is opened or closed
■Customization
Some functions can be customized. ( P. 740)

●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.

●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
