BSM (Blind Spot Monitor)

*

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 confirm-
ing safety when changing lanes.

WARNING

■

Cautions regarding the use of the sys-

tem

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The Blind Spot Monitor is a supplemen-

tary function which alerts the driver that a

vehicle is in a blind spot of the outside

rear view mirrors or is approaching rap-

idly 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 serious

injury.
As the system may not function correctly

under certain conditions, the driver’s own

visual confirmation of safety is necessary.

■

Cautions regarding the use of the sys-

tem

There is a limit to the degree of recogni-

tion accuracy and control performance

that this system can provide, do not

overly rely on this system. The driver is

always responsible for paying attention

to the vehicle’ surroundings and driving

safely.

■

To ensure the system can operate

properly

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not damage the sensors, and

always keep them clean.

●

Do not attach a sticker or install an

electronic component, such as a

backlit license plate (especially fluo-

rescent type), fog lights, fender pole or

wireless antenna near a radar sensor.

●

Do not subject the surrounding area of

the sensor to a strong impact. If sub-

jected to an impact, have the vehicle

inspected by any authorized Lexus

retailer or Lexus authorized repairer,

or any reliable repairer. If the front or

rear bumper needs to be

emoved/installed or replaced, contact

any authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

●

Do not modify, disassemble or paint

the sensors.

●

Do not attach a license plate cover.

●

Keep your tires properly inflated.

■

When to disable the function

In the following situations, disable the

function as it may operate even though

there is no possibility of a collision.

●

Failing to observe the warnings above.

●

A non-genuine Toyota suspension

(lowered suspension, etc.) is installed.

■

Notes when washing the vehicle

Do not apply intensive bursts of water or

steam to the sensor area.
Doing so may result in the sensor mal-

functioning.

●

When using a high pressure washer to

wash the vehicle, do not spray the sen-

sors 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 sen-

sor to malfunction.

rain. When the system determines that it

is normal, the system will return to nor-

mal.

●

Initialization may not have been per-

formed after a battery terminal was dis-

connected and reconnected. Initialize the

system. (

P.271) If this message contin-

ues to be displayed even after initializa-

tion, have the vehicle inspected by any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

■

If “Parking Assist Unavailable Clean

Parking Assist Sensor” is displayed on

the multi-information display

A sensor may be covered with ice, snow,

dirt, etc. Remove the ice, snow, dirt, etc.,

from the sensor to return the system to nor-

mal.
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

system will return to normal.

■

If a battery terminal has been discon-

nected and reconnected

The system needs to be initialized. To initial-

ize the system, drive the vehicle straight

ahead for 5 seconds or more at a speed of

approximately 35 km/h (22 mph) or more.

■

Sensor detection information

The following situations may occur during

use.

●

The sensor's detection areas are limited

to the areas around the vehicle front and

rear bumpers.

●

Depending on the shape of the object

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

●

There will be a short delay between

object detection and display. Even at low

speeds, there is a possibility that the

object will come within the sensor’s

detection areas before the display is

shown and the warning beep 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 buzzer if

buzzers for other systems are sounding.

■

Objects which the system may not be

properly detected

The shape of the object may prevent the

sensor from detecting it. Pay particular

attention to the following objects:

●

Wires, fences, ropes, etc.

●

Cotton, snow and other materials that

absorb sound waves

●

Sharply-angled objects

●

Low objects

●

Tall objects with upper sections project-

ing outwards in the direction of your vehi-

cle

People may not be detected if they are

wearing certain types of clothing.

■

Situations in which the system may not

operate properly

Certain vehicle conditions and the sur-

rounding environment may affect the ability

of a sensor to correctly detect objects. Par-

ticular instances where this may occur are

listed below.

●

There is dirt, snow 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 display may be dis-

played abnormally, or objects, such as a

wall, may not be detected.

●

When a sensor or the area around a sen-

sor is extremely hot or cold.
