WARNING
■Toyota Safety Sense C
The Toyota Safety Sense C is designed to operate under the assumption
that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle's surround-
ings and driving safely.

The pre-collision system is equipped with a sophisticated computer
that will record certain data, such as:• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your vehicle and the vehicle ahead or other objects)
• Images from the front sensor (available only when the pre-collision
braking function was operating)
The pre-collision system does not record conversations or other
sounds and does not record images of the inside of the vehicle.
● Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Recorded images can be erased using a specialized device.
The image recording function can be disabled. However, if the func-
tion is disabled, data from when the pre-collision system operates
will not be available.

WARNING
■ Front sensor
The front sensor uses lasers to detect vehicles ahead of your vehicle. The
front sensor is classified as class 1M laser product according to the IEC
60825-1 standard. Under normal usage conditions, these lasers are not
harmful to the naked eye. However, it is necessary to observe the following
precautions.
Failure to do so may result in the loss of eyesight or severe visual impair-
ment.
●To avoid hazardous laser radiation exposure, never attempt to disassem-
ble the front sensor (e.g. remove the lenses). When disassembled, the
front sensor is classified as a class 3B laser product according to the IEC
60825-1 standard. Class 3B lasers are hazardous and pose a risk of eye
injury under direct exposure.

WARNING
●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 flash and the
system may be temporarily disabled. In this case, use the windshield
defogger to remove the fog, etc. ( P. 205)
● 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.
● 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 your
Toyota dealer.
● 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 your Toyota dealer.
● 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
contact the lens. Also, do not touch the lens.
If the lens is dirty or damaged, contact your Toyota dealer.
● 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. Contac t your Toyota dealer for details.

PCS (Pre-Collision system)
◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and the PCS activation
indicator will flash to urge the
driver to take evasive action.
◆Pre-collision 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-collision 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.
: If equipped
The pre-collision system uses the front sensor to detect vehi-
cles in front of your vehicle. When the system determines that
the possibility of a frontal collision with a vehicle is high, a warn-
ing 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 fron-
tal collision with a vehicle 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. 168)

WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for sa fe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. 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. 170
• Conditions under which the system may not operate properly: P. 174
● Do not attempt to test the operation of the pre-collision system yourself, as
the system may not operate properly, possibly leading to an accident.
■ Pre-collision braking
●The pre-collision 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-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering w heel is turned and the system deter-
mines that the driver is taking evasive action.
● A large amount of braking force is applied while the pre-collision braking
function is operating. Additionally, as the operation of the pre-collision
braking function will be canceled after the vehicle has been stopped for
approximately 2 seconds if it is stopped by the operation of the pre-colli-
sion braking function, the driver should depress the brake pedal as neces-
sary.
● 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-collision braking function.
