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 refueling 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 discharged 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 vehicle.

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 nozzle 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.

the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.

If a sunshade was used when the vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature of the front camera to become
excessively high.

If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.

The area in front of the front
camera is obstructed, such as

Pre-collision warning

When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
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 colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.

◆

Pre-collision braking

When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.

PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and front camera
to detect vehicles and pedestrians in front of your vehicle. When
the system determines that the possibility of a frontal collision
with a vehicle or pedestrian is high, a warning operates to urge
the driver to take evasive action and the potential brake pres-
sure is increased to help the driver avoid the collision. If the sys-
tem determines that the possibility of a frontal collision with a
vehicle or pedestrian is extremely high, the brakes are automati-
cally applied to help avoid the collision or help reduce the
impact of the collision.

The pre-collision system can be disabled/enabled and the warning
timing can be changed. (

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

collision damage or injury in every situation. Do not overly rely on this sys-

tem. Failure to do so may lead to an accident, 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 effectiveness may change according to vari-

ous conditions, therefore the system may not always be able to achieve

the same level of performance.

Read the following conditions carefully. Do not overly rely on this system

and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision:



P. 244

• Conditions under which the system may not operate properly:



P. 246

●

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,

possibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking function is operating, a large amount of

braking force will be applied.

●

If the vehicle is stopped by the operation 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 accelerator pedal is being depressed

strongly or the steering wheel is being turned, the system may determine

that the driver is taking evasive action and possibly prevent the pre-colli-

sion braking function from operating.

●

In some situations, while the pre-collision braking function is operating,

operation of the function may be canceled 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 possibly delay the operation timing of

the pre-collision braking function.

Each function is operational at the following speeds:

●

Pre-collision warning:

• Vehicle speed is between approximately 7 and 110 mph (10 and 180

km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 7 and 50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 7 mph (10 km/h) or more.

●

Pre-collision brake assist:

• Vehicle speed is between approximately 20 and 110 mph (30 and 180

km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 20 and 50 mph [30 and 80 km/h].)

WARNING

■

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto-

matically drive the vehicle or reduce the amount of attention that must be

paid to the area in front of the vehicle. The driver must always assume full

responsibility for driving safely by paying careful attention to the surround-

ing conditions and operating the steering wheel to correct the path of the

vehicle. Also, the driver must take adequate breaks when fatigued, such as

from driving for a long period of time.

Failure to perform appropriate driving operations and pay careful attention

may lead to an accident, resulting in death or serious injury.

■

To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.
