CAUTION
■Limitations of the pre-collision system
Do not overly rely on the pre-collision system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other
road hazards. Failure to do so may cause an accident resulting in death or
serious injury.
■ 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 judgment
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 by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop safety.
For this reason, when encountering a dangerous situation the driver must
take direct and immediate action in order to ensure the safety of all
involved.

CAUTION
■When the sensor may not be corr ectly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● Vehicles that cut in suddenly
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
●Keep the sensor and front grille clean at all times.
Clean the sensor and front grille 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 become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your Toy-
ota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille or surrounding
area.
● Do not modify or paint the sensor and grille cover.

Monitor function and Rear Cross Traffic Alert function.
Outside rear view mirror indicator
Blind Spot Monitor function:
When a vehicle is detected in the blind spot, the outside rear view mir-
ror indicator comes on while the turn signal lever is not operated and
the outside rear view mirror indicator flashes while the turn signal lever
is operated.
Rear Cross Traffic Alert function:
When a vehicle approaching from the right or left rear of the vehicle is
detected, the outside rear view mirror indicators flash.

The Blind Spot Monitor functionThe Blind Spot Monitor function uses radar sensors to detect vehicles
that are traveling in an adjacent la ne in the area that is not reflected
in the outside rear view mirror (the blind spot), and advises the driver
of the vehicles existence via the outside rear view mirror indicator.
The Blind Spot Monitor function detection areas
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the
side of the vehicle is not in the
detection area
Approximately 9.8 ft. (3 m)
from the rear bumper
Approximately 3.3 ft. (1 m) for-

The areas that vehicles can be detected in are outlined below.
To give the driver a more consist ent time to react, the buzzer can
alert for faster vehicles from farther away.
