Vehicles that can be detected by the Blind Spot Monitor

The Blind Spot Monitor uses rear side radar sensors to detect the following vehi-
cles traveling in adjacent lanes and advises the driver of the presence of such vehi-
cles via the indicators on the outside rear view mirrors.

Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)

Vehicles that are approaching rapidly from behind in areas that are not visible
using the outside rear view mirrors (the blind spots)

■

■

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 “Parking Assist Unavailable” is dis-

played on the multi-information 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 system will return to nor-

mal.

●

WARNING

■

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 your Lexus dealer. If the

front or rear bumper needs to be

removed/installed or replaced, con-

tact your Lexus dealer.

●

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 Lexus 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 vehi-

cle, do not direct steam too close to

the sensors as doing so may cause a

sensor to malfunction.

■

Sensor detection information

●

The sensor’s detection areas are limited

to the areas around the vehicle’s 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 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 prop-

erly detect

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 displayed 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.

●

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 clearance sonar of other

vehicles or other devices which produce

ultrasonic 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 ultrasonic waves (ex.

skirts with gathers or frills).

●

When objects that are not perpendicular

to the ground, not perpendicular to the

vehicle traveling direction, uneven, or

waving are in the detection range.

●

Strong wind is blowing.

●

When driving in inclement weather such

as fog, snow or a sandstorm.

●

When an object that cannot be detected

is between the vehicle and a detected

object.

●

If an object such as a vehicle, motorcycle,

bicycle or pedestrian cuts in front of the

vehicle or runs out from the side of the

vehicle.

●

If the orientation of a sensor has been

changed due to a collision or other

impact.

●

When equipment that may obstruct a

sensor is installed, such as a towing eye-

let, bumper protector (an additional trim

●

If the front of the vehicle is raised or low-

ered due to the carried load.

●

If the vehicle cannot be driven in a stable

manner, such as when the vehicle has

been in an accident or is malfunctioning.

●

When tire chains, a compact spare tire or

an emergency tire puncture repair kit are

used.

■

Situations in which the system may

operate even if there is no possibility of a

collision

In some situations, such as the following, the

system may operate even though there is

no possibility of a collision.

●

When driving on a narrow road.

●

When driving toward a banner, flag, low-

hanging branch or boom barrier (such as

those used at railroad crossings, toll

gates and parking lots).

●

When there is a rut or hole in the surface

of the road.

●

When driving on a metal cover (grating),

such as those used for drainage ditches.

●

When driving up or down a steep slope.

●

If a sensor is hit by a large amount of

water, such as when driving on a flooded

road.

●

There is dirt, snow, water drops or ice on

a sensor. (Cleaning the sensors will

resolve this problem.)

●

A sensor is coated with a sheet of spray

or heavy rain.

●

When driving in inclement weather such

as fog, snow or a sandstorm.

●

The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:

Approximately 1.0 ft. (30 cm)



When 2 or more objects are
detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer will repeat a long
tone, followed by fast beeps.

Situations in which the system may

operate even if there is no possibility of a

collision

Instances of the RCTA function unneces-

sarily detecting a vehicle and/or object may

increase in the following situations:

●

When the parking space faces a street

and vehicles are being driven on the

street.

●

When the distance between your vehicle

and metal objects, such as a guardrail,

PKSB (Parking Support
Brake)

*

The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object is high, a
warning operates to urge the driver
to take evasive action. If the system
determines that the possibility of a
collision with a detected object is
extremely high, the brakes are
automatically applied to help avoid
the collision or help reduce the
impact of the collision.
