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 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 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.

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 reflected from the
surface of the sunshade may cause
the temperature 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 condi-
tioning system to increase the tem-
perature around the front camera.

PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects (
P.235) 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 driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking
operations under any circum-
stances. This system will not
prevent collisions or lessen col-
lision damage or injury in every
situation. Do not overly rely on
this system. Failure to do so
may lead to an accident, result-
ing in death or serious injury.

WARNING
●
Although this system is
designed to help avoid a colli-
sion 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 sys-
tem may operate even if there is
no possibility of a collision:
• Conditions under which the sys-
tem may not operate properly:
●
Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, possi-
bly 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 function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 seconds. Depress the
brake pedal as necessary.
●
The pre-collision braking func-
tion 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-collision braking function
from operating.
●
In some situations, while the
pre-collision braking function is
operating, operation of the func-
tion 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 tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■
Emergency steering assist
●
As emergency steering assist
operation will be canceled when
the system determines that lane
departure prevention function
has been completed.
●
Emergency steering assist may
not operate or may be cancel in
the following cases as the sys-
tem may determine 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 deter-
mine that the driver is taking
evasive action and the emer-
gency steering assist may not
operate.

WARNING
• In some situations, while the
emergency steering assist is
operating, operation of the func-
tion may be canceled 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 steer-
ing wheel is held firmly or is
operated in the opposite direc-
tion to that which the system is
generating torque, the function
may be canceled.
