After performing a washing and wiping

operation several times, the wipers operate

one more time after a short delay to prevent

dripping.
However, this final wiper operation will not

be performed while driving.

■

Effects of vehicle speed on wiper opera-

tion (vehicles with rain-sensing wind-

shield wipers)

Vehicle speed affects the following even

when the wipers are not in AUTO mode.

●

Intermittent wiper interval

●

Wiper operation when the washer is

being used (delay until drip prevention

wiper sweep occurs)

With low speed windshield wiper operation

selected, wiper operation will be switched

from low speed to intermittent wiper opera-

tion only when the vehicle is stationary.

■

Raindrop sensor (vehicles with

rain-sensing windshield wipers)

●

The raindrop sensor judges the amount

of raindrops.

An optical sensor is adopted. It may not

operate properly when sunlight from the

rising or setting of the sun intermittently

strikes the windshield, or if bugs etc. are

present on the windshield.

4-3. Operating the lights and wipers

●

If the wiper is turned to AUTO mode

while the engine switch is in IGNITION

ON mode, the wipers will operate once

to show that AUTO mode is activated.

●

If the temperature of the raindrop sensor

is 185°F (85°C) or higher, or -22°F

(-30°C) or lower, automatic operation

may not occur. In this case, operate the

wipers in any mode other than AUTO

mode.

■

When the windshield wipers are in tem-

porary operation (vehicles with

rain-sensing windshield wipers)

AUTO mode cannot be activated even if is

pressed.

■

If no windshield washer fluid sprays

Check that the washer nozzles are not

blocked if there is washer fluid in the wind-

shield washer fluid reservoir.

WARNING

■

Caution regarding the use of wind-

shield wipers in AUTO mode

The windshield wipers may operate

unexpectedly if the sensor is touched or

the windshield is subject to vibration in

AUTO mode. Take care that your fingers

or anything else do not become caught

in the windshield wipers.

■

Caution regarding the use of washer

fluid

When it is cold, do not use the washer

fluid until the windshield becomes warm.

The fluid may freeze on the windshield

and cause low visibility. This may lead to

an accident, resulting in death or serious

injury.

NOTICE

■

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 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.

4-5. Using the driving support systems

Driving

The system can detect the following
(The detectable objects differs
depending on the function.):



Vehicles



Bicyclists



Pedestrians

■

Pre-collision warning

When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-

sage will be displayed on the
multi-information display to urge the
driver to take evasive action.

■

Pre-collision brake assist

When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.

■

Pre-collision braking

If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.

■

Emergency steering assist

If the system determines that the possi-
bility of a frontal collision is high and
that there is sufficient space for the
vehicle to be steered into within its
lane, and the driver has begun evasive
maneuver or steering, emergency
steering assist will assist the steering
movements to help enhance the vehi-
cle stability and for lane departure pre-
vention. During operation, the
indicator will illuminate in green.

PCS (Pre-Collision System)

The pre-collision system uses a
radar sensor and front camera to
detect objects (



P.165) in front of

the vehicle. When the system
determines that the possibility of a
frontal collision with an 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 deter-
mines that the possibility of a frontal
collision with an object 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. (

■

Intersection right/left turn assis-
tance

If the system determines that there is a
high possibility of a collision in the fol-
lowing situations, it will assist with
Pre-collision warning and, if necessary
Pre-collision braking.
Depending on the configuration of the
intersection, it may not be possible to
support.



When you turn right/left at an inter-
section and cross the path of an
oncoming vehicle



When you turn right/left, pedestrian
is detected in the forward direction
and estimated to enter your vehi-
cle’s path (bicyclists are not
detected.)

■

Suspension control (if equipped)

When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem (



P.229) will control the damp-

ing force of the shock absorbers to
help maintain an appropriate vehicle
posture.

WARNING

■

Limitations of the pre-collision system

●

The driver is solely responsible for safe

driving. Always drive safely, taking

care to observe your surroundings.

Do not use the pre-collision system

instead of normal braking operations

under any circumstances. This system

will not prevent collisions or lessen col-

lision damage or injury in every situa-

tion. Do not overly rely on this system.

Failure to do so may lead to an acci-

dent, resulting in death or serious

injury.

●

Although this system is designed to

help avoid a collision or help reduce

the impact of the collision, its effective-

ness may change according to various

conditions, therefore the system may

not always be able to achieve the same

level of performance.

Read the following conditions care-

fully. Do not overly rely on this system

and always drive carefully.

• Conditions under which the system

may operate even if there is no possi-

bility of a collision:



P.171

167

4-5. Using the driving support systems

Driving

WARNING

• Conditions under which the system

may not operate properly:



P.172

●

Do not attempt to test the operation of

the pre-collision system yourself.

Depending on the objects used for

testing (dummies, cardboard objects

imitating detectable objects, etc.), the

system may not operate properly, pos-

sibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking func-

tion is operating, a large amount of

braking force will be applied.

●

If the vehicle is stopped by the opera-

tion of the pre-collision braking func-

tion, the pre-collision braking function

operation will be canceled after

approximately 2 seconds. Depress the

brake pedal 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.

●

In some situations, while the pre-colli-

sion braking function is operating,

operation of the function may be can-

celed if the accelerator pedal is

depressed strongly or the steering

wheel is turned and the system deter-

mines that the driver is taking evasive

action.

●

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 braking function.

■

Emergency steering assist

●

As emergency steering assist opera-

tion will be canceled when the system

determines that lane departure pre-

vention function has been completed.

●

Emergency steering assist may not

operate or may be canceled in the fol-

lowing cases as the system may deter-

mine the driver is taking actions.

• If the accelerator pedal is being

depressed strongly, the steering wheel

is being operated sharply, the brake

pedal is being depressed or the turn

signal lever is being operated. In this

case, the system may determine that

the driver is taking evasive action and

the emergency steering assist may not

operate.

• In some situations, while the emer-

gency steering assist is operating,

operation of the function may be can-

celed if the accelerator pedal is

depressed strongly, the steering wheel

is operated sharply or the brake pedal

is being depressed and the system

determines that the driver is taking

evasive action.

• When the emergency steering assist is

operating, if the steering wheel is held

firmly or is operated in the opposite

direction to that which the system is

generating torque, the function may be

canceled.

■

When to disable the pre-collision sys-

tem

In the following situations, disable the

system, as it may not operate properly,

possibly leading to an accident resulting

in death or serious injury:

●

When the vehicle is being towed

●

When your vehicle is towing another

vehicle

●

When transporting the vehicle via

truck, boat, train or similar means of

transportation
