WARNING
●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. C ontact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer 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)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound, the PCS activation indi-
cator will flash
*1 or a warning
message will be displayed in
the multi-information display
*2,
and the system will urge the
driver to take evasive action.
*1: Vehicles with monochrome display.
*2: Vehicles with color display.
: If equipped
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. 294)

◆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. 298
• Conditions under which the system may not operate properly: P. 3 0 2
● 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 bei ng 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.

WARNING
■Pre-crash braking
● While driving, such as when driving through a railway crossing, the system
may determine that the possibility of a collision with an object, such as rail-
way crossing barrier, is high and operate the pre-crash braking function.
To move the vehicle in an emergency, such as if the system operates in a
railway crossing, perform the following operations and then take the nec-
essary measures to ensure your safety.
• If the vehicle has been stopped, depress the accelerator pedal.
•If the vehicle is decelerating, fully depress the accelerator pedal.
( P. 297)
• Disable the pre-crash safety system. ( P. 294)
■ 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
● 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 condition of the tires is poor and they do not perform well
( P. 508)
● 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

■Enabling/disabling the pre-crash safety system
Press the PCS switch for 3 seconds or more.
The PCS warning light will turn on and a message will be displayed in the
multi-information display, when the system is turned off.
To enable the system, press the PCS switch again.
The pre-crash safety system is enabled each time the engine is started.

Changing the pre-crash warning timing
Vehicles with monochrome display
Press the PCS switch to turn on the PCS activation indicator and dis-
play the current warning timing in the multi-information display. Each
time the PCS switch is pressed in the displayed state, the timing for
the warning changes as follows:
If the operation timing setting has been changed, the setting will be
retained the next time the engine is started.
Far
The warning will begin to operate
earlier than with the default timing.
Middle
This is the default setting.
Near
The warning will begin to operate
later than with the default timing.
