The pre-crash safety system is equipped with a sophisticated com-
puter that will record certain data, such as:
• How far (if at all) the driver was depressing the accelerator and/or
brake pedal
• Vehicle speed
• Operation status of the pre-crash safety system functions
• Information (such as the distance and relative speed between your
vehicle and the vehicle ahead or another object)
The pre-crash safety system does not record conversations, sounds
or pictures.
● Data usage
Toyota may use the data recorded in these computers 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
The front sensor is located on the
upper side of the windshield. It
consists of 2 types of sensors,

WARNING
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 harm-
ful to the naked eye. However, it is necessary to observe the following precau-
tions.
Failure to do so may result in the loss of eyesight or severe visual impairment.
● 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.
● Do not attempt to look into the front sensor with a magnifying glass, micro-
scope or other optical instrument within a distance of less than 100 mm
(3.9 in.).

NOTICE
■Front sensor
Observe the following to ensure that the sensor operates correctly:
● Do not attach window tinting to the windshield.
● On cold days when there is a large temperature difference between the
vehicle interior and outside air temperatures, the windshield fogs up easily.
If the part of the windshield in front of the front sensor becomes fogged up
or covered with condensation or ice, the system temporarily stops working
and the PCS warning light flashes. In that case, use the front defroster to
remove the fog, condensation, or ice. ( P. 288)
● Keep the windshield clean at all times. Also, even when using a glass
coating agent, if water droplets and so forth form on the windshield, use
the wipers to remove them.
The pre-crash safety system may not function properly if the windshield is
dirty or covered with an oily film, water droplets, snow, etc.
If the inner side of the windshield where the front sensor is installed is dirty,
do not attempt to remove the front sensor. Contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.
●Do not attach objects, such as stickers,

PCS (Pre-Crash Safety system)
◆Pre-crash warning
When the system determines
that the possibility of a frontal
collision with a vehicle is high, a
buzzer will sound and the PCS
activation indicator will flash to
urge the driver to take evasive
action.
◆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.
: 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,
pre-crash warning urges the driver to take evasive action and
the potential brake pressure will be 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 to
the vehicle occupants and the vehicle in the collision.
The pre-crash warning timing can be changed or the system can be
enabled/disabled, as necessary, by operating the switch. ( P. 217)
