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 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.
If a sensor or its surrounding area on the
rear bumper is dirty or covered with snow,
the Blind Spot Monitor may not operate
and a warning message (

P. 304) will be

displayed. In this situation, clear off the
dirt or snow and drive the vehicle with the
operation conditions of the BSM function
(

P. 308) satisfied for approximately 10

minutes. If the warning message does not
disappear, have the vehicle inspected by
your Toyota dealer.

4-5. Using the driving support systems

Drivin

The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane 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 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-
ward of the rear bumper

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 BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance 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.

Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.

The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously.

• Front and rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)

When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances, the beep will repeat a long
tone, followed by fast beeps.

The intuitive parking assist can be operated when

The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).

Front corner sensors:
• The shift lever is not in P.
• The vehicle speed is approximately 6 mph (10 km/h) or less.

Rear corner and rear center sensors:
The shift lever is in R.

Intuitive parking assist display
When an obstacle is detected while the rear view monitor system or pan-
oramic view monitor (if equipped) is in use, the warning indicator will appear
in the upper part of the screen even if the display setting has been set to off.

Sensor detection information

The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.

Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.

Obstacles may not be detected if they are too close to the sensor.

There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within the sen-
sor’s detection.

Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.

It might be difficult to hear beeps due to the volume of audio/visual system
or air flow noise of the air conditioning system.

Certification (Canada only)
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme a la norme NMB-001 du Canada.

WARNING

When using the Intuitive parking assist-sensor
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.

Do not use the sensor at speeds in excess of 6 mph (10 km/h).

The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.

Do not install accessories within the sensors’ detection areas.
