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)

The Blind Spot Monitor detection areas

The areas that vehicles can be detected in are outlined below.

The range of each detection area is:

Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either side of the vehicle

P.236)

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.

Initialization may not have been per-

formed after a 12-volt battery terminal 

was disconnected and reconnected. Ini-

tialize the system. (

P.239)

If this message continues to be displayed 
even after initialization, have the vehicle 
inspected by your Lexus dealer.

If a 12-volt battery terminal has been 

disconnected 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 

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.

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

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

strip, etc.), bicycle carrier, or snow plow.

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.

When strong winds are blowing.

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.

Buzzer operation and distance to 
an object

A buzzer sounds when the sensors are 
operating.

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.

Automatic buzzer mute function: 
After a buzzer begins sounding, if 
the distance between the vehicle 
and the detected object does not 
become shorter, the buzzer will be 
muted automatically. (However, if 
the distance between the vehicle 
and object is 1.0 ft. [30 cm] or less, 
this function will not operate.)

The buzzer sounds volume can be 
adjusted. (

Operation of the RCTA function

The RCTA function uses rear side 
radar sensors to detect vehicles 
approaching from the right or left at 
the rear of the vehicle and alerts the 
driver of the presence of such vehicles 
by flashing the outside rear view mirror 
indicators and sounding a buzzer.

Conditions under which the system will 

not detect a vehicle

The RCTA function is not designed to 

detect the following types of vehicles 

and/or objects:

Vehicles approaching from directly 

behind

Vehicles backing up in a parking space 

next to your vehicle

Vehicles that the sensors cannot detect 

due to obstructions

Guardrails, walls, signs, parked vehicles 
and similar stationary objects

*

Small motorcycles, bicycles, pedestrians, 
etc.

*

Vehicles moving away from your vehicle

Vehicles approaching from the parking 
spaces next to your vehicle

*

The distance between the sensor and 

approaching vehicle gets too close

*

: Depending on the conditions, detection 

of a vehicle and/or object may occur.

Situations in which the system may not 

operate properly

The RCTA function may not detect vehicles 

correctly in the following situations:

When the sensor is misaligned due to a 

strong impact to the sensor or its sur-

rounding area.

When mud, snow, ice, a sticker, etc., is 

covering the sensor or surrounding area 

on the rear bumper.

When driving on a road surface that is 

wet with standing water during bad 

weather, such as heavy rain, snow, or fog.

When multiple vehicles are approaching 

with only a small gap between each vehi-

When a vehicle is approaching at high 

speed.

When equipment that may obstruct a 

sensor is installed, such as a towing eye-

let, bumper protector (an additional trim 

strip, etc.), bicycle carrier, or snow plow.

When backing up on a slope with a sharp 

change in grade.

When backing out of a sharp angle park-

ing spot.

When towing a trailer.

When there is a significant difference in 

height between your vehicle and the 

vehicle that enters the detection area.

When a sensor or the area around a sen-

sor is extremely hot or cold.

If the suspension has been modified or 

tires of a size other than specified are 

installed.

If the front of the vehicle is raised or low-

ered due to the carried load.

When turning while backing up.

When a vehicle turns into the detection 

area.

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, 

wall, sign, or parked vehicle, which may 

reflect electrical waves toward the rear of 

the vehicle, is short.

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.
