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.

220

4-4. Refueling

Press the switch to open the fuel
filler door.

The fuel filler door will open within about

10 seconds of the switch being pressed.

Before refueling is possible, a message will

be shown on the multi-information display

in the instrument cluster to indicate the

progress of the fuel filler door opener.

Turn the fuel tank cap slowly and
remove it, then put it into the holder
on the fuel filler door.

■

If the fuel filler door cannot be opened



P.515

After refueling, turn the fuel tank cap
until you hear a click. Once the cap is
released, it will turn slightly in the oppo-
site direction.

NOTICE

■

Refueling

●

Finish refueling within 30 minutes. If

more than 30 minutes passes, the

internal valve closes. In this condition,

fuel may overflow during the refueling

process.

Press the fuel filler door opener switch

again.

●

Make sure that the fuel filler door lock

is not pushed by the fuel nozzle boot,

etc. If the lock is held, the internal valve

closes and fuel may overflow. To pre-

vent it, press the fuel filler door opener

switch again.

●

Do not spill fuel during refueling.

Doing so may damage the vehicle,

such as causing the emission control

system to operate abnormally or dam-

aging fuel system components or the

vehicle’s painted surface.

Driving

: If equipped

During controlled driving, the driver
monitor camera detects the position
and direction the driver is facing, and
whether their eyes are opened or
closed. Through this, the system deter-
mines if the driver is checking their sur-
roundings and if the driver can perform
driving operations.
In order to operate properly, the driver
monitor camera requires an unob-
structed view of the driver’s face. If the
steering column or seat position is
either too high or too low, or if any
other condition is present that
obstructs the driver monitor camera’s
view of the driver’s face, some driving
support systems may not operate
properly, or a warning message may be
displayed.

■

Warning function

In situations such as the following, a
buzzer will sound and a message will
be displayed to warn the driver.



When the system determines that

the driver is not paying attention to
the road or their eyes are closed



When the driver’s face cannot be
detected or the system determines
that the driver has poor driving pos-
ture

When the seated position of the driver is
such that the upper or lower part of the
meter is not visible, the driver’s entire face
may not be recognized by the driver moni-
tor camera. To mitigate the appearance of
this warning, adjust the steering wheel and
seat position so the driver can see the
entire meter.

■

Face identification

The driver monitor is used as a device
to identify faces in order to identify an
individual.

For safe use

●

The driver monitor is not designed to

prevent the driver from driving care-

lessly or having a poor driving posture.

Pay careful attention to the surround-

Face identification

Face identification starts when the door is

opened then closed.
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 can be deleted by your-

self.

●

For the handling of face information,

please consent to the following before

using it:

• Face identification does not guarantee a

complete identity authentication, colla-

tion, or identification.

• When face information registration fails

frequently or face identification fails fre-

quently, the driver cameras should be

cleaned or face information should be

registered again.

• 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.

• 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:

●

When a part of the driver’s face (eye-

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.

●

When the driver is closing eyes

●

When a non-registered driver is a twin,

etc. with a registered driver, whose face

looks quite alike with each other

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.233) 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. (

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.

Operating conditions of each function of the pre-collision system

The pre-collision system is enabled and the system determines that the possibility of a frontal

collision with a detected object is high.
However, the system will not operate in the following situations:

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

has completed.

●

Depending on operations performed

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.

• While the emergency steering assist is

operating, if the steering wheel is held

or turned in the opposite direction of

system operation, emergency steer-

ing assist operation will be canceled.
