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 sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing 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 f uel 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 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 possi-
ble 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.

covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter ( P.324).
When the temperature around the
front camera is out side of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight r eflected from the
surface of the sunshade may cause
the temperature of the front camera
to become exce ssively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.

The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
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 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
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 possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
■Emergency steering assist
If the system determines that
the possibility of a frontal colli-
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.228) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion 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
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.231)
