Toyota Safety Sense P
The Toyota Safety Sense P consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:
WARNING
■Toyota Safety Sense P
The Toyota Safety Sense P 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)
• Image information from the camera 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 image information can be erased using a specialized
device.
The image information recording function can be disabled. How-
ever, if the function is disabled, data from when the pre-collision
system operates will not be available.

WARNING
■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera 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 a glass coating agent is applied to the windshield, it will still be neces-
sary to use the windshield wipers to remove water droplets, etc. from
the area of the windshield in front of the camera sensor.
• If the inner side of the windshield where the camera sensor is installed
is dirty, contact your Toyota dealer.
●If the part of the windshield in front of the camera sensor is fogged up or
covered with condensation or ice, use the windshield defogger to remove
the fog, condensation or ice. (→P. 372, 380)
●If water droplets cannot be properly removed from the area of the wind-
shield in front of the camera 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 get the camera sensor wet.
●Do not allow bright lights to shine into the camera sensor.
●Do not dirty or damage the camera 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 install an antenna or attach stick-
ers (including transparent stickers) or
other items to the area of the windshield

PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians
*1 in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision 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 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. 220)
*1: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact your Toyota dealer for
details.
