Situation

Actions

When the area around a sensor is covered
with dirt, moisture (fogged up, covered with
condensation, ice, etc.), or other foreign
matter

To clean the part of the windshield in front of
the front camera, use the windshield wipers
or the windshield defogger of the air condi-
tioning system (



P.307).

When the temperature around the front
camera is outside of the operational range,
such as when the vehicle 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 system to decrease the tem-
perature 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 cam-
era to become excessively high.

If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, 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 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.

Q

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.

PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and front camera to detect vehi-
cles and pedestrians

*1

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 pressure is increased to help the driver avoid the collision. If the system
determines that the possibility of a frontal collision with a vehicle or pedestrian
is extremely high, the brakes are automatically applied to help avoid the colli-
sion or help reduce the impact of the collision.

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

Q

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.

Q

Pre-collision braking

When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem 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.

Q

Suspension control

When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem (



P.291) will control the damping

force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.

WARNING

Q

Limitations of the pre-collision sys-

tem

O

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.

O

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:



P.236

• Conditions under which the system

may not operate properly:



P.238

O

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.

Q

Pre-collision braking

O

When the pre-collision braking func-

tion is operating, a large amount of

braking force will be applied.

Q

Enabling/disabling the pre-colli-
sion system

The pre-collision system can be
enabled/disabled on

(

the multi-information display.

The system is automatically enabled each
time the engine switch is turned to ON.

If the system is disabled, the PCS warn-

WARNING

O

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 2seconds. Depress the

brake pedal as necessary.

O

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.

O

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.

O

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.

Q

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:

O

When the vehicle is being towed

O

When your vehicle is towing another

vehicle

O

When transporting the vehicle via

truck, boat, train or similar means of

transportation

O

When the vehicle is raised on a lift with

the engine running and the tires are

the surrounding conditions and operat-

ing the steering wheel to correct the path

of the vehicle. Also, the driver must take

adequate breaks when fatigued, such as
