PCS (Pre-Crash Safety system)

The pre-crash safety system uses a radar sensor and camera

sensor to detect vehicles and pedestrians*1 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*2 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. (P. 372)

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

detection function may not be available. Contact any authorized Toyota

dealer or repairer, or another duly qualified and equipped professional for

details.

*2: Depending on the region in which the vehicle was sold, the pre-crash

braking function (automatic braking function) may not be available. Con-

tact any authorized Toyota dealer or repairer, or another duly qualified

and equipped professional for details.

◆ 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.

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. 376

• Conditions under which the system may not operate properly: P. 378

●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*3

● 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.

*3: Depending on the region in which the vehicle was sold, the pre-crash

braking function may not be available.

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
