Detection range of the sensors

Approximately 3.3 ft. (100 cm)

Approximately 4.9 ft. (150 cm)

Approximately 2.0 ft. (60 cm)

The diagram shows the detection range of 
the sensors. Note that the sensors cannot 
detect obstacles that are extremely close 
to the vehicle.
The range of the sensors may change 

depending on the shape of the object etc.

Multi-information display, head-up 
display and Center Display

Sensors that detect an obstacle will illu-
minate continuously or blink.

NOTICE

If the display flashes or shows continu-

ously without beeping, except when 

the mute function has been turned on.

If a display error occurs, first check the 

sensor. 

If the error occurs even when there is 

no ice, snow or mud on the sensor, it is 

likely that the sensor is malfunctioning.

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.

Buzzer operation and distance to 
an obstacle

A buzzer sounds when the sensors are 
operating.
 The buzzer beeps faster as the vehi-

cle approaches an obstacle. When 
the vehicle comes within the follow-
ing distance of the obstacle, the 
buzzer sounds continuously:

• Front center sensors: Approximately 1.0 

ft. (30 cm)

• Corner sensors: Approximately 1.0 ft. 

(30 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.

BSM function: 
When a vehicle is detected in a blind spot 
of the outside rear view mirrors or 
approaching rapidly from behind into a 
blind spot, the outside rear view mirror 
indicator on the detected side will illumi-
nate. If the turn signal lever is operated 
toward the detected side, the outside rear

BSM (Blind Spot Monitor)

*

The Blind Spot Monitor uses the 
sensors installed behind the rear 
bumper. The system is intended to 
assist the driver check areas that 
are not easily visible. The system 
has the following 2 functions:
 The BSM (Blind Spot Monitor) 

function

Assists the driver in making a deci-
sion when changing lanes
 The RCTA (Rear Cross Traffic 

Alert) function

Assists the driver when backing up
These functions use same sensors.

WARNING

Handling the radar sensor

Blind Spot Monitor sensors are installed 

behind the left and right sides of the rear 

bumper respectively. Observe the fol-

lowing to ensure the Blind Spot Monitor 

can function correctly.

Keep the sensors and the surrounding 

areas on the rear 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.221) will be displayed. In this situ-

ation, clear off the dirt or snow and 

drive the vehicle with the operation 

conditions of the BSM function 

(

P.224) satisfied for approximately 

10 minutes. If the warning message 

does not disappear, have the vehicle 

inspected by your Lexus dealer.

Driving

Operation of the BSM function

The BSM function uses radar sensors to detect the following vehicles traveling in 
adjacent lanes and advises the driver of the presence of such vehicles via the indi-
cators 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)

WARNING

Do not subject a sensor or its sur-

rounding area on the rear bumper to a 

strong impact. 

If a sensor is moved even slightly off 

position, the system may malfunction 

and vehicles may not be detected cor-

rectly. 

In the following situations, have your 

vehicle inspected by your Lexus 

dealer.

• A sensor or its surrounding area is 

subject to a strong impact.

• If the surrounding area of a sensor is 

scratched or dented, or part of them 

has become disconnected.

Do not disassemble the sensor.

Do not attach stickers to the sensor or 

surrounding area on the rear bumper.

Do not modify the sensor or surround-

ing area on the rear bumper.

Do not paint the rear bumper any 

color other than an official Lexus color.

: The greater the difference in speed between your vehicle and the detected vehicle is, 

the farther away the vehicle will be detected, causing the outside rear view mirror indi-
cator to illuminate or flash.

Conditions under which the BSM func-

tion may not function correctly

The BSM function may not detect vehi-

cles 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-

cle

• When the distance between your vehicle 

and a following vehicle is short

• When there is a significant difference in 

speed between your vehicle and the vehi-

cle that enters the detection area

• When the difference in speed between 

your vehicle and another vehicle is 

changing

• When a vehicle enters a detection area 

traveling at about the same speed as your 

vehicle

• As your vehicle starts from a stop, a vehi-

cle remains in the detection area

• When driving up and down consecutive 

steep inclines, such as hills, dips in the 

road, etc.

• When driving on roads with sharp bends, 

consecutive curves, or uneven surfaces

• When vehicle lanes are wide, or when 

driving on the edge of a lane, and the 

vehicle in an adjacent lane is far away 

from your vehicle

• When an accessory (such as a bicycle 

carrier) or towing eyelet is installed to the 

rear of the vehicle

• When there is a significant difference in 

height between your vehicle and the 

vehicle that enters the detection area

• Immediately after the BSM function is 

turned on

Instances of the BSM function unneces-

sarily detecting a vehicle and/or object 

may increase in the following situations:

• When the sensor is misaligned due to a 

strong impact to the sensor or its sur-

rounding area

• When the distance between your vehicle 

and a guardrail, wall, etc. that enters the 

detection area is short

• When driving up and down consecutive 

steep inclines, such as hills, dips in the 

road, etc.

• When vehicle lanes are narrow, or when 

driving on the edge of a lane, and a vehi-

cle traveling in a lane other than the adja-

cent lanes enters the detection area

• When driving on roads with sharp bends, 

consecutive curves, or uneven surfaces

• When the tires are slipping or spinning

• When the distance between your vehicle 

and a following vehicle is short

• When an accessory (such as a bicycle 

carrier) or towing eyelet is installed to the 

rear of the vehicle

WARNING

Cautions regarding the use of the 

function

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 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 BSM function. 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.

Operation of the RCTA function

The RCTA function uses 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.
