PCS (Pre-Collision System)∗

The pre-collision system uses a radar sensor and camera sen-

sor to detect vehicles and pedestrians*1 in front of your vehicle.

When the system determines that the possibility of a frontal col-

lision 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-collision system can be disabled/enabled and the warning

timing can be changed. (→P. 246)

*1: Depending on the region in which the vehicle was sold, the pedestrian

detection function may not be available. See the following table for

details.

◆ 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 colli-

sion is high, the system applies greater braking force in relation to

how strongly the brake pedal is depressed.

4

◆ Pre-collision 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.

 Region B

(The pedestrian detection function is not available)

The pre-collision system is enabled and the system determines that the pos-

sibility of a frontal collision with a vehicle is high.

Each function is operational at the following speeds:

● Pre-collision warning:

• Vehicle speed is between approximately

10 and 110 mph (15 and

180 km/h).

• The relative speed between your vehicle and the vehicle ahead is

approximately 7 mph (10 km/h) or more.

● Pre-collision brake assist:

• Vehicle speed is between approximately

20 and 110 mph (30 and

180 km/h).

• The relative speed between your vehicle and the vehicle ahead is

approximately 20 mph (30 km/h) or more.

● Pre-collision braking:

• Vehicle speed is between approximately

10 and 110 mph (15 and

4

180 km/h).

• The relative speed between your vehicle and the vehicle ahead is

approximately 7 mph (10 km/h) or more.

The system may not operate in the following situations:

● If a battery terminal has been disconnected and reconnected and then the

vehicle has not been driven for a certain amount of time

● If the shift lever is in R

● If VSC is disabled (only the pre-collision warning function will be opera-

tional)

■ Pedestrian detection function*2

The pre-collision system detects pedestri-

ans based on the size, profile, and motion

of a detected object. However, a pedes-

trian may not be detected depending on

the surrounding brightness and the

motion, posture, and angle of the

detected object, preventing the system

from operating properly. (→P. 254)

*2: For countries/areas specified as Region B (→P. 242), the pedestrian detec-

tion function may not be available.
