PCS (Pre-Crash Safety system)

∗

∗

: If equipped

The pre-crash safety system uses a radar sensor and camera
sensor to detect vehicles and pedestrians in front of your vehi-
cle. 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 auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.

The pre-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (

◆

Pre-crash 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-crash brake assist

When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.

◆

Pre-crash braking

When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system 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.

WARNING

■

Limitations of the pre-crash safety system

●

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings. 
Do not use the pre-crash safety system instead of normal braking opera-
tions under any circumstances. This system will not prevent collisions or
lessen collision damage or injury in every situation. Do not overly rely on
this system. Failure to do so may lead to an accident, 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 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 system may operate even if there is no pos-

sibility of a collision: 

→P. 293

• Conditions under which the system may not operate properly: 

→P. 296

●

Do not attempt to test the operation of the pre-crash safety system your-
self, as the system may not operate properly, possibly leading to an acci-
dent.

■

Pre-crash braking

●

When the pre-crash braking function is operating, a large amount of brak-
ing force will be applied.

●

If the vehicle is stopped by the operation of the pre-crash braking function,
the pre-crash braking function operation will be canceled after approxi-
mately 2 seconds. Depress the brake pedal as necessary.

●

The pre-crash braking function 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-crash
braking function from operating.

●

In some situations, while the pre-crash braking function is operating, oper-
ation of the function may be canceled if the accelerator pedal is depressed
strongly or the steering wheel is turned and the system determines 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 possibly delay the operation timing of
the pre-crash braking function.

WARNING

■

When to disable the pre-crash safety system
In the following situations, disable the system, as it may not operate prop-
erly, 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

●

When the vehicle is raised on a lift with the engine running and the tires
are allowed to rotate freely

●

When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal-
ancer

●

When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons

●

If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning

●

When the vehicle is driven in a sporty manner or off-road

●

When the tires are not properly inflated

●

When the tires are very worn

●

When tires of a size other than specified are installed

●

When tire chains are installed

●

When a compact spare tire or an emergency tire puncture repair kit is used

●

If equipment (snow plow, etc.) that may obstruct the radar sensor or cam-
era sensor is temporarily installed to the vehicle
