The Toyota Safety Sense P consists of the following drive assis t
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 assu mption
that the driver will drive safely, and is designed to help redu ce the impact to
the occupants and the vehicle in the case of a collision or ass ist 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 vehicl e’s surround-
ings and driving safely.

5-5. Using the driving support systems
The pre-collision system is equipped with a sophisticated compu ter
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 dist ance and relative speed between y our
vehicle and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-col li-
sion braking function or the pre-collision brake assist functio n was
operating)
The pre-collision system does not record con versations, sounds or
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 exc ept:
• With the consent of the vehicle owner or with the consent of t he
lessee if the vehicle is leased
• In response to an official request by the police, a court of l aw 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 f unc-
tion is disabled, data from when the pre-collision system opera tes
will not be available.

WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to
an accident resulting in death or serious injury.
● Keep the radar sensor and front g rille emblem clean at all times.
● Do not attach accessories, stickers (including transparent stic kers) or
other items to the radar sensor, front grille emblem or surroun ding area.
● Do not subject the radar sensor or surrounding area to a strong impact.
If the radar sensor, front grille, or front bumper has been sub jected to a
strong impact, have the vehicle inspected by your Toyota dealer .
● Do not disassemble the radar sensor.
● Do not modify or paint the radar sensor, front grille emblem or surrounding
area.
● If the radar sensor, front grille, or front bumper needs to be removed and
installed, or replaced, contact your Toyota dealer.

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 t o remove
the fog, condensation or ice. ( P. 492, 502)
● If water droplets cannot be properly removed from the area of t he wind-
shield in front of the camera sensor by the windshield wipers, replace the
wiper insert or wiper blade.
• To replace the wiper insert: P. 628
• If the wiper blades need to be replaced, contact your Toyota d ealer.
● 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 dea ler.
● Do not get the camera sensor wet.
● Do not allow bright lights to shine into the camera sensor.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the camera sensor (shaded
area in the illustration).
A: From the top of the windshield to
approximately 0.4 in. (1 cm) below the
bottom of the camera sensor
B: Approximately 7.9 in. (20 cm)
(Approximately 4.0 in. (10 cm) to the
right and left from the center of the cam-
era sensor)

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 a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedest rians in front of your vehicle.
When the system determines that t he possibility of a frontal col-
lision with a vehicle or pedest rian 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 possi bility 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 th e
impact of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 3 7 3 )

◆Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brak e pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to hel p avoid the collision or reduce the
collision speed.
