The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time after a short delay

to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
When the power switch is in ON mode
and the headlights are on, if the lever is
pulled, the headlight cleaners will operate
once. After this, the headlight cleaners will
operate every 5th time the lever is pulled.

The windshield wiper and washer can be

operated when

The power switch is in ON mode.

Effects of vehicle speed on wiper opera-

tion

Even when the wipers are not in AUTO

mode, vehicle speed affects the time until

the 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.
(However, when the sensor sensitivity is

adjusted to the highest level, the mode can-

not be switched.)

Raindrop sensor

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.

If the wiper switch is turned to AUTO

position while the power switch is in ON

mode, the wipers will operate once to

show that AUTO mode is activated.

If the temperature of the raindrop sensor

When AUTO is selected and the wind-

shield wipers are operating, if a front door is

opened while the vehicle is stopped and the

P position is selected, operation of the

windshield wipers will be stopped to pre-

vent anyone near the vehicle from being

sprayed by water from the wipers. When

the front door is closed, wiper operation will

resume.

To protect the windshield wipers

If movement of the windshield wipers is

largely restricted by a foreign object such

as snow, the operation of the windshield

wipers may be stopped automatically to

protect the windshield wipers. In this case,

turn the windshield wiper switch off and

remove the foreign object, and then use the

windshield wipers.

When stopping the hybrid system in an

emergency while driving

If the windshield wipers are operating when

the hybrid system is stopped, the windshield

wipers will operate in high speed operation.

After the vehicle is stopped, operation will

return to normal when the power switch is

turned to ON mode, or operation will stop

when the driver’s door is opened.

When the windshield wipers are not
being used, they retract to below the

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 fin-

gers 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

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehi-

cle has a fuel tank opening that only accom-

modates the special nozzle on unleaded

fuel pumps.

Opening 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 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.

: If equipped

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.224) 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-

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.303) will control the damp-

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

WARNING

Limitations of the pre-collision sys-

tem

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.

226

4-5. Using the driving support systems

WARNING

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.230

• Conditions under which the system

may not operate properly:



P.232

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 cancel 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.
