filler door.

Opening the fuel tank cap

Perform the following steps to open
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

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 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

PCS (Pre-Collision System)

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



P.223) 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 disa-
bled/enabled and the warning timing
can be changed. (
