AFS (Adaptive Front-lighting System)
secures excellent visibility at intersec-
tions and on curves by automatically

of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input.

AFS operates at speeds of 6 mph (10

When the steering wheel or turn
signal lever is operated while the
headlights are on (low beam), a cor-
nering light will turn on and light up
the direction of movement of the
vehicle. The cornering lights are
designed to ensure excellent visibil-
ity when making a turn at an inter-
section.

However, when vehicle speed is approxi-
mately 22 mph (35 km/h) or higher, the
cornering lights will not turn on.

Conditions to turn the high beams on/off

automatically

●

When all of the following conditions are

met, the high beams will be turned on

automatically (after approximately 1 sec-

ond):

• The vehicle speed is approximately 21

mph (34 km/h) or more.

• The area ahead of the vehicle is dark.

• There are no vehicles ahead with head-

lights or tail lights turned on.

• There are few streetlights on the road

ahead.

●

If any of the following conditions is met,

the high beams will turn off automatically:

• The vehicle speed is below approxi-

mately 17 mph (27 km/h).

• The area ahead of the vehicle is not dark.

• Vehicles ahead have their headlights or

tail lights turned on.

• There are many streetlights on the road

■

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

●

The high beams may be turned off if a

vehicle ahead that is using fog lights with-

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.

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 nec-

essary.

■

To prevent incorrect operation of the

Automatic High Beam system

Do not overload the vehicle.

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

repeatedly when the fuel tank is nearly full.

Opening the fuel tank cap

Perform the following steps to open
the fuel tank cap:

Before refueling the vehicle

WARNING

■

When refueling the vehicle

Observe the following precautions while

refueling the vehicle. Failure to do so may

result in death or serious injury.

●

After exiting the vehicle and before

opening the fuel door, touch an

unpainted metal surface to discharge

any static electricity. It is important to

discharge static electricity before refu-

eling because sparks resulting from

static electricity can cause fuel vapors

to ignite while refueling.

●

Always hold the grips on the fuel tank

cap and turn it slowly to remove it.

A whooshing sound may be heard

when the fuel tank cap is loosened.

Wait until the sound cannot be heard

before fully removing the cap. In hot

weather, pressurized fuel may spray

out of the filler neck and cause injury.

●

Do not allow anyone that has not dis-

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.

■

When refueling

Observe the following precautions to

prevent fuel overflowing from the fuel

tank:

●

Securely insert the fuel nozzle into the

fuel filler neck.

●

Stop filling the tank after the fuel noz-

zle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Do not spill fuel during refueling.

Doing so may damage the vehicle, such

as causing the emission control system to

operate abnormally or damaging fuel

system components or the vehicle’s
