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. 301
• Conditions under which the system may not operate properly: P. 3 0 5
● 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. 300)
• Disable the pre-crash safety system. ( P. 297)
■ 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. 503)
● 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

■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.

■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle is high.
Each function is operational at the following speeds:
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 85 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 15 km/h (10 mph) or more.
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (20 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (20 mph) or more.
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 km/h (7 mph) 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-crash warning function will be operational)
■ Cancelation of the pre-crash braking
● If either of the following occur while the pre-crash braking function is operat-
ing, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braki ng function will be canceled after the
vehicle has been stopped for approximately 2 seconds.

■ If the PCS warning light flashes or illuminates (vehicles with mono-
chrome display)
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will be cleared and the system
will become operational when normal operating conditions return:
• When the area around the front sensor is hot, such as after the vehicle
has been parked in the sun
• When the windshield is fogged up or covered with condensation or ice
• When driving in conditions where the front sensor cannot detect an
object, such as in the dark (at night on a road without street lights or other
lights, etc.), when bright light is shining into the sensor, or in snow or fog.
• When the front sensor or the area around either sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash or illuminate, the system may be
malfunctioning. Have the vehicle inspected by any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer immediately.
■ If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi-information di splay (vehicles with color display)
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
● In the following situations, the warning light will turn off, the message will
disappear and the system will beco me operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
( P. 434, 444)
• When driving in conditions where the front sensor cannot detect an
object, such as in the dark (at night on a road without street lights or other
lights, etc.), when bright light is shining into the sensor, or in snow or fog.
• When the front sensor or the area around either sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sens or is obstructed, such as when the
hood is open
● If the PCS warning light continues to flash or illuminate or the warning mes-
