BSM (Blind Spot Moni-

tor)

The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.

WARNING

■

Cautions regarding the use of

the system

The driver is solely responsible for

safe driving. Always drive safely,

taking care to observe your sur-

roundings.
The Blind Spot Monitor is a sup-

plementary function which alerts

the driver that a vehicle is in a

blind spot of the outside rear view

mirrors or is approaching rapidly

from behind into a blind spot. Do

not overly rely on the Blind Spot

Monitor. As the function cannot

judge if it is safe to change lanes,

over reliance could lead to an

accident resulting in death or seri-

ous injury.
As the system may not function

correctly under certain condi-

tions, the driver’s own visual con-

firmation of safety is necessary.

If “Clean Parking Assist Sen-

sor” is displayed on the multi-

information display

A sensor may be covered with water

drops, ice, snow, dirt, etc. Remove

the water drops, ice, snow, dirt, etc.,

from the sensor to return the system

to normal.
Also, due to ice forming on a sensor

at low temperatures, a warning

message may be displayed or the

sensor may not be able to detect an

object. Once the ice melts, the sys-

tem will return to normal.
If a warning message is displayed

even if the sensor is clean, there

may be a sensor malfunction. Have

the vehicle inspected by your Toyota

dealer.

■

If “Parking Assist Unavailable”

is displayed on the multi-infor-

mation display

Water may be continuously flowing

over the sensor surface, such as in

a heavy rain. When the system

determines that it is normal, the sys-

■

Sensor detection information

●

The sensor’s detection areas are

limited to the areas around the

vehicle’ front and rear bumpers.

●

The following situations may occur

during use.

• Depending on the shape of the

object and other factors, the

detection distance may shorten, or

detection may be impossible.

• Detection may be impossible if

static objects draw too close to the

sensor.

• There will be a short delay

between static object detection

and display (warning buzzer

sounds). Even at low speeds,

there is a possibility that the object

will come within 11.9 in. (30 cm)

before the display is shown and

the warning buzzer sounds.

• It might be difficult to hear the

buzzer due to the volume of the

audio system or air flow noise of

the air conditioning system.

• It may be difficult to hear the

sound of this system due to the

buzzers of other systems.

■

Objects which the system may

not be properly detected

The shape of the object may pre-

vent the sensor from detecting it.

Pay particular attention to the follow-

ing objects:

WARNING

●

When using a high pressure

washer to wash the vehicle, do

not spray the sensors directly,

as doing so may cause a sensor

to malfunction.

●

When using steam to clean the

vehicle, do not direct steam too

close to the sensors as doing so

may cause a sensor to malfunc-

tion.

projecting outwards in the direc-

tion of your vehicle

■

Situations in which the system

may not operate properly

Certain vehicle conditions and the

surrounding environment may affect

the ability of a sensor to correctly

detect objects. Particular instances

where this may occur are listed

below.

●

There is dirt, snow, water drops or

ice on a sensor. (Cleaning the

sensors will resolve this problem.)

●

A sensor is frozen. (Thawing the

area will resolve this problem.)

In especially cold weather, if a

sensor is frozen the sensor dis-

play may be displayed abnormally,

or objects, such as a wall, may not

be detected.

●

When a sensor or the area around

a sensor is extremely hot or cold.

●

On an extremely bumpy road, on

an incline, on gravel, or on grass.

●

When vehicle horns, vehicle

detectors, motorcycle engines, air

brakes of large vehicles, the clear-

ance sonar of other vehicles or

other devices which produce ultra-

sonic waves are near the vehicle

●

A sensor is coated with a sheet of

spray or heavy rain.

●

If objects draw too close to the

sensor.

●

When a pedestrian is wearing

clothing that does not reflect ultra-

sonic waves (ex. skirts with gath-

ers or frills).

●

When objects that are not perpen-

dicular to the ground, not perpen-

dicular to the vehicle traveling

direction, uneven, or waving are in

the detection range.

●

Strong wind is blowing

●
