AHB (Automatic High
Beam)

The Automatic High Beam uses a
front camera located on the upper
portion of the windshield to detect
the brightness of the lights of vehi-
cles ahead, streetlights, etc., and
automatically changes the head
lights between the high beams and
low beams.

matically:

• 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 lights

on.

• There are few streetlights or other lights

on the road ahead.

●

In the following situations, the high beams

may not be automatically changed to the

low beams:

• When a vehicle cuts in front of your vehi-

cle

• When another vehicle crosses in front of

the vehicle

• When vehicles ahead are repeatedly

detected and then hidden due to

repeated curves, road dividers or road-

side trees

• When a vehicle ahead approaches from

a far lane

• When a vehicle ahead is far away

• When a vehicle ahead has no lights

• When the lights of a vehicle ahead are

dim

●

The headlights may change to the low

beams 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 may

cause the high beams to change to the

low beams, or the low beams to remain

on.

●

The following may change the timing at

which the headlights change to the low

beams:

• The brightness of lights of vehicles ahead

• The movement and direction of vehicles

ahead

• The distance between the vehicle and a

vehicle ahead

• When a vehicle ahead only has lights illu-

minated on one side

• When a vehicle ahead is a two-wheeled

vehicle

curve, condition of the road surface, etc.)

• The number of passengers and amount of

luggage

●

The headlights may change between the

high beams and low beams unexpectedly.

●

Bicycles and other small vehicles may not

be detected.

●

In the following situations, the system may

not be able to correctly detect the bright-

ness of the surroundings. 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 change between the

high beams and low beams.

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

■

Refueling

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

painted surface.

226

4-4. Refueling

Press the switch to open the fuel
filler door.

Turn the fuel tank cap slowly and

In face identification, facial traits are digi-

tized and stored in a built-in computer, to be

used for identification in My Settings.

●

Face image or video are not stored. Voice

is not stored either.

●

Digitized face information is not used for

any purpose other than identification in

My Settings. Additionally, face informa-

tion cannot be decoded and will not be

disclosed or provided to a third party.

●

Face information stored in the vehicle

computer cannot be decoded or moved

to another media. Therefore, it is neces-

sary to register face information again

once it is deleted or relevant parts are

replaced.

●

Face information can be deleted by your-

self.

●

Once deleted, face information cannot

be restored. It is necessary to register

face information again.

■

Situations where face identification may

not be performed correctly

This system is designed for use to identify

facial traits. In the following situations, face

information may not be able to be regis-

tered or identified correctly:

●

brows, eyes, nose, or mouth) is not visible

●

When the driver is wearing glasses/sun

glasses, a face mask, muffler, etc.

●

When the driver is not facing front

●

When part of driver’s face is covered with

hair, beard, a hand, clothes, jewelry, etc.

●

Pre-collision warning

When the system determines that the
possibility of a collision is high, a buzzer
will sound and an icon and warning
message will be displayed on the
multi-information display to urge the
driver to take evasive action.

PCS (Pre-Collision System)

The pre-collision system uses sen-
sors to detect objects (



P.238) in

the path of the vehicle. When the
system determines that the possi-
bility of a frontal collision with a
detectable object is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a collision is extremely high,
the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (

P.247)

WARNING

■

For safe use

●

Driving safely is solely the responsibil-

ity of the driver. Pay careful attention to

the surrounding conditions in order to

ensure safe driving.

Never use the pre-collision system in

place of normal braking operations. This

system cannot help avoid or reduce the

impact of a collision in every situation.

Over-reliance on this system to drive the

vehicle safely may lead to an accident

resulting in death or serious injury.

●

Although the pre-collision system is

designed to help avoid or help reduce

the impact of a collision, its effective-

ness may change according to various

conditions. Therefore, it may not

always be able to achieve the same

level of performance.

Read the following items carefully. Do

not overly rely on this system and

always drive carefully.

WARNING

■

Pre-collision braking

●

When the pre-collision braking func-

tion is operating, a large amount of

braking force will be applied.

●

The pre-collision braking function is

not designed to hold the vehicle

stopped. If the vehicle is stopped by

pre-collision brake control, the driver

should operate the brakes immedi-

ately as necessary.

●

The pre-collision braking function may

not operate if certain operations are

performed by the driver. If the acceler-

ator pedal is being depressed strongly

or the steering wheel is being turned,

the system may determine that the

driver is taking evasive action and pos-

sibly prevent the pre-collision braking

function from operating.

●

If the brake pedal is being depressed,

the system may determine that the

driver is taking evasive action and pos-

sibly delay the operation timing of the

pre-collision brake control.

■

Acceleration Suppression at Low

Speed

If the steering wheel is being turned, the

system may determine that the driver is

taking evasive action and possibly pre-

vent the Acceleration Suppression at

Low Speed function from operating or

possibly causing its operation to be can-

celed.

■

Emergency steering assist

●

The emergency steering assist will be

canceled when the system determines

that lane departure prevention control

by the driver, emergency steering

assist may not operate or operation

may be canceled.

• If the accelerator pedal is depressed

strongly, the steering wheel is turned

heavily, the brake pedal is depressed,

or the turn signal lever is operated, the

system may determine that the driver

is taking evasive action and the emer-

gency steering assist may not operate.

• While the emergency steering assist is

operating, if the accelerator pedal is

depressed strongly, the steering wheel

is turned heavily, or the brake pedal is

depressed, the system may determine

that the driver is taking evasive action

and emergency steering assist opera-

tion may be canceled.

Driving

lights are flashing.

While the Acceleration Suppression at Low Speed function is operating, if any of the follow-

ing are performed, the low speed sudden acceleration suppression function operation will

be cancelled:
• The accelerator pedal is released.
• The steering wheel is operated heavily or suddenly

■

Detection of detectable objects

Objects are detected based on their size,

shape, and movement.
Depending on the ambient brightness,

movement, posture and direction of a

detectable object, it may not be detected

and the system may not operate properly.
The system detects shapes, such as the fol-

lowing, as detectable objects.

■

Situations in which the system may

operate even though the possibility of a

collision is not high

●

In certain situations, such as the following,

the system may determine that the possi-

bility of a collision is high and operate:

• When passing a detectable object

• When changing lanes while overtaking a

detectable object

• When suddenly approaching a detect-

able object

• When approaching a detectable object

or other object on the roadside, such as

guardrails, utility poles, trees, walls, etc.

• When there is a detectable object or

other object by the roadside at the

entrance of a curve

• When there are patterns or a painting

ahead of the vehicle that may be mistaken

for a detectable object

• When passing a detectable object that is

changing lanes or turning left/right

• When passing a detectable object which

is stopped to make a left/right turn

• When a detectable object stops immedi-

ately before entering the path of the vehi-

cle

4-5. Using the driving support systems

• When passing through a location with a

structure above the road (traffic sign, bill-

board, etc.)

• When approaching an electric toll gate

barrier, parking lot barrier, or other bar-

rier that opens and closes

• When turning left/right and an oncoming

vehicle, oncoming motorcycle, pedes-

trian or bicycle crosses in front of the

vehicle

• When attempting to turn left/right in front

of an oncoming vehicle, oncoming

motorcycle, pedestrian or bicycle

• When turning left/right and an oncoming

vehicle, oncoming motorcycle, pedes-

trian or bicycle stops or changes course

immediately before entering the path of

the vehicle

• When turning left/right and an oncoming

vehicle turns left/right in front of the vehi-

cle

• When the steering wheel is operated

toward the path of an oncoming vehicle

• When there is an object moving above or

under the road

■

Situations in which the system may not

operate properly

●

In certain situations, such as the following,

a detectable object may not be detected

by the front sensors, and the system may

not operate properly:

• When a detectable object is approaching

your vehicle

• When your vehicle or a detectable object

is wandering

• When a detectable object makes an

abrupt maneuver (such as sudden swerv-

ing, acceleration or deceleration)

• When suddenly approaching a detect-

able object

• When the detectable object is near a

wall, fence, guardrail, manhole cover,

steel plate on the road surface, or

another vehicle

• When there is a structure above a detect-

able object

• When part of a detectable object is hid-

den by another object (large luggage,

umbrella, guardrail, etc.)

• When multiple detectable objects are

overlapping

• When a bright light, such as the sun, is

reflecting off of a detectable object

• When a detectable object is white and

looks extremely bright

• When the color or brightness of a detect-

able object causes it to blend in with its

surroundings

• When a detectable object cuts in front of

or suddenly emerges in front of your

vehicle

• When approaching a vehicle which is

diagonal

• If a bicycle is a child sized bicycle, is car-

rying a large load, is carrying an extra

passenger, is carrying a forward leaning

rider, or has an unusual shape (bicycles

equipped with a child seat, tandem bicy-

cles, etc.)

• If a pedestrian or bicycle is shorter than

approximately 3.2 ft. (1 m) or taller than

approximately 6.5 ft. (2 m).

• When the silhouette of a pedestrian or

bicycle is unclear (such as when they are

wearing a raincoat, long skirt, etc.)

• When a pedestrian is bending forward or

squatting

• When a pedestrian or bicycle is moving

at high speed
