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.

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.

WARNING
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT. There are limits to the degree of assistance the system can
provide, so please keep in mind the following important points.
● Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that
allows careless or inattentive driving, and it is not a system that can assist
the driver in low-visibility conditions. It is still necessary for the driver to
pay close attention to the vehicle’s surroundings.
● Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-collision system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary for the
driver to remain vigilant and to determine whether or not there is a possi-
bility of collision in any given situation.
● Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system is not capable of auto-
matically avoiding a collision or bringing the vehicle to a stop safely with-
out appropriate operations performed by the driver. For this reason, when
encountering a dangerous situation the driver must take direct and imme-
diate action in order to ensure the safety of all involved.

WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the
Blind Spot Monitor function. The function cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resulting in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.
