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.

BSM (Blind Spot Monitor)
The Blind Spot Monitor is a system that has 2 functions;
● The Blind Spot Monitor function
Assists the driver in making t he decision when changing lanes
● The Rear Cross Traffic Alert function
Assists the driver when backing up
These functions use same sensors.
Summary of the Blind Spot Monitor
BSM outside rear view mirror indicators
Blind Spot Monitor function:
When a vehicle is detected in the blind spot, the BSM outside rear view
mirror indicator on the detected side illuminates. If the turn signal lever is
operated when a vehicle is in the blind spot, the BSM outside rear view
mirror indicator flashes.
Rear Cross Traffic Alert function:
When a vehicle approaching from the right or left rear of the vehicle is
detected, the BSM outside rear view mirror indicators flash.
Rear Cross Traffic Alert buzzer (Rear Cross Traffic Alert function
only)
When a vehicle approaching from the right or left rear of the vehicle is
detected, a buzzer sounds from behind the rear seat.

Certification for the Blind Spot Monitor system
FCC ID: OAYSRR2A
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.
FCC Warning
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
The Blind Spot Monitor function uses radar sensors to detect vehicles
that are traveling in an adjacent lane in the area that is not reflected in
the outside rear view mirror (the b lind spot), and advises the driver of
the vehicles existence via the BSM outside rear view mirror indicator.
WARNING
■ Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor system can function correctly.
● Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may mal-
function and vehicles that enter the detection area may not be detected. If
the sensor or surrounding area is subject to a strong impact, always have
the area inspected by your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.

●Keep the sensor and its surrounding
area on the bumper clean at all times.

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

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.
