WARNING

■ To avoid malfunction of the front sensor

Observe the following precautions.

Otherwise, the front sensor may not operate properly, possibly leading to an

accident resulting in death or serious injury.

● Keep the windshield clean at all times. If the windshield is dirty or covered

with an oily film, water droplets, snow, etc., clear the windshield. If the

inner side of the windshield in front of the front sensor is dirty, contact any

authorized Toyota dealer or repairer, or another duly qualified and

equipped professional.

● Do not attach objects, such as stickers,

transparent stickers, etc., and so forth,

to the outer side of the windshield in

front of the front sensor (shaded area in

the illustration).

A: From the top of the windshield to

approximately 10 cm (4.0 in.) below the

bottom of the front sensor

B: Approximately 20 cm (7.9 in.) (Approximately 10 cm (4.0 in.) to the

right and left from the center of the front sensor)

● Do not install or attach anything to the

inner side of the windshield under the

front sensor (shaded area in the illustra-

tion).

A: Approximately 10 cm (4.0 in.) (Start-

ing from the bottom of the front sensor)

B: Approximately

20 cm

(7.9 in.)

(Approximately 10 cm (4.0 in.) to the

right and left from the center of the front

sensor)

● If there is a large difference in temperature between the inside and outside

of the vehicle, such as in winter, the windshield is likely to fog up easily. If

the part of the windshield in front of the front sensor is fogged up or cov-

ered with condensation or ice, the PCS warning light may illuminate and

the system may be temporarily disabled. In this case, use the windshield

defogger to remove the fog, etc. (P. 406, 413)

● If the area of the windshield in front of the front sensor is covered with

water droplets, use the windshield wipers to remove them.

If the water droplets are not sufficiently removed, the performance of the

front sensor may be reduced.

4-5. Toyota Safety Sense

257

WARNING

● If water droplets cannot be properly removed from the area of the wind-

shield in front of the front sensor by the windshield wipers, replace the

wiper insert or wiper blade.

If the wiper inserts or wiper blades need to be replaced, contact any autho-

rized Toyota dealer or repairer, or another duly qualified and equipped pro-

fessional.

● Do not attach window tinting to the windshield.

● Replace the windshield if it is damaged or cracked.

If the windshield needs to be replaced, contact any authorized Toyota

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

● Do not install an antenna in front of the sensor.

● Do not get the front sensor wet.

● Do not allow bright lights to shine into the front sensor.

● Do not dirty or damage the front sensor.

When cleaning the inside of the windshield, do not allow glass cleaner to

4

contact the lens. Also, do not touch the lens.

If the lens is dirty or damaged, contact any authorized Toyota dealer or

repairer, or another duly qualified and equipped professional.

● Do not subject the front sensor to a strong impact.

● Do not change the installation position or direction of the front sensor or

remove it.

● Do not disassemble the front sensor.

● Do not install an electronic device or device that emits strong electric

waves near the front sensor.

● Do not modify any components of the vehicle around the front sensor

(inside rear view mirror, sun visors, etc.) or ceiling.

● Do not attach any accessories that may obstruct the front sensor to the

hood, front grille or front bumper. Contact any authorized Toyota dealer or

repairer, or another duly qualified and equipped professional for details.

● If a surfboard or other long object is to be mounted on the roof, make sure

that it will not obstruct the front sensor.

● Do not modify the headlights or other lights.

● Do not attach anything to or place anything on the dashboard.

■ Installation area of front sensor on windshield

When the windshield is fogging up easily, the glass around the front sensor

may be hot due to the heater running. If the glass is touched, it may result in

burns.

PCS (Pre-Crash Safety system)

The pre-crash safety system uses the front sensor to detect

vehicles in front of your vehicle. When the system determines

that the possibility of a frontal collision with a vehicle 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 is extremely high, the brakes are

automatically 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. (P. 261)

◆ 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 with a vehicle 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 with a vehicle is high, the system warns the driver. If the sys-

tem determines that the possibility of a 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 and reduce the impact of a

collision, its effectiveness 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 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. 263

4

• Conditions under which the system may not operate properly: P. 267

● 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

● 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.

● A large amount of braking force is applied while the pre-crash braking

function is operating. Additionally, as the operation of the pre-crash brak-

ing function will be canceled after the vehicle has been stopped for

approximately 2 seconds if it is stopped by the operation of the pre-crash

braking function, the driver should depress the brake pedal as necessary.

● 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.
