Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc., that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■ When there is a malfunction in the system, or if the system is temporar-
ily unavailable
The PCS warning light flashes and a warning message is shown on the multi-
information display. If a warning message is shown on the multi-information
display, read the message and follow the instructions.
■ When the TRAC and VSC are turned off
●When the TRAC and VSC operations are turned off ( →P. 234), the pre-colli-
sion brake assist and pre-collision braking are also turned off. However, the
alert function operates.
● The PCS warning light turns on and the “Pre-Collision Brake is Disabled due
to VSC OFF” is displayed on the multi-information display.

Driving

WARNING
■Limitations of the pre-collision system
The driver is solely responsible for safe 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
damage or injuries in all cases. Do not overly rely on this system. Failure to
do so may cause an accident, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of col-
lisions.
However, the system operates differently depending on the situation
(→ P. 240).
As a result, the same level of performance may not be expected in all
cases. Also, the pre-collision brakes may not operate if the driver is
depressing the brake pedal or turning the steering wheel, as the system will
determine such conditions as collision avoidance operations.
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an
accident.
● Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may not work
normally or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your
Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● If the radar sensor needs to be replaced, contact your Toyota dealer.

●The seat belt reminder light is flashing
Are the driver and the front passenger wearing the seat belts? (→P. 371)
●The brake system warning light is on
Is the parking brake released? (→P. 186)
Depending on the situation, other types of warning buzzer may also sound.
( →P. 369, 376)
●Did anyone inside the vehicle open a door during setting the alarm?
The sensor detects it and the alarm sounds. ( →P. 74)
To stop the alarm, turn the power switch to ON mode or start the fuel cell sys-
tem.
●Is the electronic key left inside the vehicle?
Check the message on the multi-information display. ( →P. 376)
●When a warning light turns on or a warning message or indicator is dis-
played, refer to P. 369, 376.
●Stop the vehicle in a safe place and replace the flat tire with the spare
tire. ( →P. 381)
●Try the procedure for when the vehicle becomes stuck in mud, dirt, or
snow. ( →P. 412)
