the daytime running light system offers 

greater durability and consumes less 

electricity, so it can help improve fuel 

economy.

■

Headlight control sensor

The sensor may not function properly if an 

object is placed on the sensor, or anything 

that blocks the sensor is affixed to the wind-

shield.

Doing so interferes with the sensor detect-

ing the level of ambient light and may cause 

the automatic headlight system to malfunc-

tion.

The level of the headlights is automatically 

adjusted according to the number of pas-

sengers and the loading condition of the 

vehicle to ensure that the headlights do not 

interfere with other road users.

■

Windshield wiper linked headlight illu-

mination

When driving during daytime with the 
headlight switch turned to 

, if the wind-

shield wipers are used, the headlights will 

turn on automatically after several seconds

■

Camera sensor detection information

●

The high beams may not be automatically 

turned off in the following situations:

• When a vehicle suddenly appears from 

around a curve

• When the vehicle is cut in front of by 

another vehicle

• When vehicles ahead cannot be 

detected due to repeated curves, road 

dividers or roadside trees

• When vehicles ahead appear in a far-

away lane on a wide road

• When the lights of vehicles ahead are not 

on

AHB (Automatic High 
Beam)

The Automatic High Beam uses a 
camera sensor located behind the 
upper portion of the windshield to 
assess the brightness of the lights of 
vehicles ahead, streetlights, etc., 
and automatically turns the high 
beams on or off as necessary.

Driving

●

The high beams may be turned off if a 

vehicle ahead that is using fog lights with-

out 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 opera-

tional 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 in the vehicle

●

The high beams may turn on or off unex-

pectedly.

●

Bicycles or similar vehicles may not be 

detected.

●

In the following situations the system may 

not be able to correctly detect the sur-

rounding 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 neces-

sary 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 dam-

aged

• 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 inter-

mittently changing brightness and dark-

ness

• 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 dam-

aged 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 

repeatedly in an abnormal manner

• When the driver believes that the high 

beams may be flashing or dazzling 

pedestrians or other drivers

charged static electricity from their 

body to come close to an open fuel 

tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that are 

harmful if inhaled.

●

Do not smoke while refueling the vehi-

cle.

Doing so may cause the fuel to ignite 

and cause a fire.

●

Do not return to the vehicle or touch 

any person or object that is statically 

charged.

This may cause static electricity to 

build up, resulting in a possible ignition 

hazard.
