With the headlights on, push the
lever away from you to turn on the
high beams.
Pull the lever toward you to the center
position to turn the high beams off.
Pull the lever toward you and release
it to flash the high beams once.
You can flash the high beams with the
headlights on or off.
AFS (Adaptive Front-lighting System) secures excellent visibility at intersections
and on curves by automatically adjusting the direction of the light axis of the
headlights according to vehicle speed and the degree of the tire’s angle as con-
trolled by steering input.
AFS operates at speeds of 6 mph (10 km/h) or higher.
●
When the steering wheel or turn signal lever is operated while the headlights
are on (low beam), a cornering light will turn on and light up the direction of
movement of the vehicle. The cornering lights are designed to ensure excel-
lent visibility when making a turn at an intersection.
However, when vehicle speed is approximately 22 mph (35 km/h) or higher, the cor-
nering lights will not turn on.
●
When the shift lever is in R while the headlights are on (low beam), both cor-
nering lights will turn on. This is designed to enhance visibility when parking.

Daytime running light system
●
The daytime running lights illuminate using the same lights as the parking lights and illu-
minate brighter than the parking lights.
●
To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when all of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the
(Canada only),
or
*
position
*
: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking brake is set
again.
●
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●
Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■
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 headlights come on: The headlights and tail lights turn off 30 seconds after a
door is opened and closed if the engine switch is turned to ACCESSORY mode or
turned off. (The lights turn off immediately if
on the key is pressed after all the doors
are locked.)
●
When only the tail lights come on: The tail lights turn off automatically if the engine
switch is turned to ACCESSORY mode or turned off and the driver’s door is opened.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to
or
.
■
Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted 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.
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.

Battery-saving function
In order to prevent the battery of the vehicle from discharging, if the headlights and/or tail
lights are on 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:
●

ahead, streetlights, etc., and automatically turns the high beams on or off as
necessary.
WARNING
■
Limitations of the Automatic High Beam
Do not overly rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning the high beams on or off manually if necessary.

Camera sensor detection information
●

●
The high beams may be turned off 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 and other
reflective objects may cause the high beams to change to the low beams, or the low
beams to remain on.
●
The following factors may affect the amount of time taken for the high beams to turn on
or off:
• The brightness of the 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
• The condition of the road (gradient, curve, condition of the road surface, etc.)

●
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 equal to that of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ahead 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 intermittently 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 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 titling 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
