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

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 (
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. (

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 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.
●
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:

Driving
WARNING
• Conditions under which the system
may not operate properly:
●
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 canceled 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.
■
When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●
When the vehicle is being towed
●
When your vehicle is towing another
vehicle
●
When transporting the vehicle via
truck, boat, train or similar means of
transportation
