Notes for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
■ Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.

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 pr e-collision system functions
• Information (such as the distanc e and relative speed between your
vehicle and the vehicle ahead or other objects)
• Images from the front sensor (ava ilable only when the pre-collision
braking function was operating)
The pre-collision sy stem 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 reco rded 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.
● 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.).

WARNING
■To avoid malfunction of the front sensor
Observe the following precautions.
Otherwise, the front 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 the
inner side of the windshield in front of the front sensor is dirty, contact your
Toyota dealer.
● 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. 372)
● 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.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration).

◆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.
◆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 sy stem warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically appli ed to help avoid the collision or
reduce the collision speed.
PCS (Pre-Collision System)
: 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 collisi on 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 determin es 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. 227)
