This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 328 ft. (100 m) ahead, determines  the current vehicle-to-vehicle following 
distance, and operates to maintain a suit able following distance from the vehicle 
ahead.
Note that vehicle-to-vehicle  distance will close in when traveling on downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle distance 
can also be set by operating the vehicle-to-vehicle distance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of  you, the system automatically decelerates 
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies 
the brakes (the stop lights will come on at this time). The sy stem will respond to changes in 
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by 
the driver. Approach warning warns you when th e system cannot decelerate sufficiently to 
prevent your vehicle from closing in on the vehicle ahead.
Example of acceleration 
When there are no longer any preceding  vehicles driving slower than the set 
speed
The system accelerates until the set speed is re ached. The system then returns to constant 
speed cruising.

WARNING
■When using the intuitive parking 
assist
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 use the sensor at speeds in 
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving 
forward or reversing, check the areas 
surrounding the vehicle (especially the 
sides of the vehicle) for safety, and 
drive slowly, using the brake to control 
the vehicle’s speed.
●Do not install accessories within the 
sensors’ detection areas.
●The area directly under the bumpers is 
not detected.
Thin posts or objects lower than a sen-
sor may not be detected when 
approached, even if they have been 
detected once.
■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.
●The vehicle is equipped with a fender 
pole, wireless antenna or fog lights.
●The front or rear bumper or a sensor 
receives a strong impact.
●A non-genuine Lexus suspension 
(lowered suspension, etc.) is installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
■When using intuitive parking assist
In the following situations, the system 
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle 
checked by your Lexus dealer.
●The intuitive parking assist operation 
display flashes or shows continuously, 
and a buzzer sounds when no objects 
are detected.
●If the area around a sensor collides 
with something, or is subjected to 
strong impact.
●If the bumper or grille collides with 
something.
●If the display flashes or is displayed 
continuously and a buzzer does not 
sound, except when the mute function 
has been turned on.
●If a display error oc curs, 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.

■The intuitive parking assist can be oper-
ated when
●Front center sensors:
• The engine switch is in IGNITION ON  mode.
• The shift lever is in a position other than P 
or R.
• The vehicle speed is less than about 6  mph (10 km/h).
●Front corner sensors:
• The engine switch is in IGNITION ON 
mode.
• The shift lever is in  a position other than P.
• The vehicle speed is less than about 6 
mph (10 km/h).
(At any speed when the  shift lever is in R)
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON  mode.
• The shift lever is in R.
■Muting the buzzer sound
●To mute the buzzer sound:
The buzzer can be temporarily muted by 
pressing “OK” of the meter control 
switches while an obstacle detection dis-
play is shown on the multi-information dis-
play.
●To cancel the mute:
Mute will be automatically canceled in the 
following situations.
• When the shift position is changed  (except shifting from D to N, or N to D).
• When the vehicle speed has reached or  exceeded 6 mph (10 km/h) with the shift 
position in D.
• When the intuitive par king assist is turned 
off once and turned on again. • When the engine switch is turned off 
once and turned to IGNITION ON 
mode again.
■If “Clean Parking Assist Sensor” is dis-
played 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.
■Sensor detection information
●The following situations may occur 
during use.
• The sensors may be able to only detect  objects near the fron t 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 di splay. Even at low 
speeds, there is a  possibility that the 
object will come within the sensor’s 
detection areas befo re 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.
■Conditions under wh ich the function 
may not function correctly
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.
WARNING
●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.

If a vehicle approaching from the right or 
left at the rear of the vehicle is detected, a 
buzzer will sound. The buzzer also sounds 
for approximately 1 second immediately 
after the BSM main swit ch is operated to 
turn the system on.
■Outside rear view mirror indicator visi-
bility
In strong sunlight, the  outside rear view mir-
ror indicator may be  difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear 
over loud noises, such as if the audio system 
volume is high.
■When “Blind Spot Monitor Unavailable” 
is shown on the multi-information dis-
play
Ice, snow, mud, etc., may be attached to the 
rear bumper around the sensors. ( P.183) 
The system should return to normal opera-
tion after removing the ice, snow, mud, etc. 
from the rear bumper. Additionally, the sen-
sors may not operate normally when driving 
in extremely hot or cold environments.

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.290) will be displayed. In this sit-
uation, clear off the dirt or snow and 
drive the vehicle with the operation 
conditions of the BSM function 
(  P.185) satisfied for approximately 
10 minutes. If the warning message 
does not disappear, have the vehicle 
inspected by your Lexus dealer.
●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.

The BSM function uses radar sensors to detect the following vehicles traveling in 
adjacent lanes and advises the driver of th e presence of such vehicles via the indi-
cators on the outside rear view mirrors.
WARNING
●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.
■Cautions regarding the use of the 
function
The driver is solely responsible for safe 
driving. Always driv e 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.
The RCTA function is only a supplemen-
tary function which alerts the driver that a 
vehicle is approaching from the right or 
left at the rear of the vehicle. As the 
RCTA function may not function cor-
rectly under certain conditions, the 
driver’s own visual confirmation of safety 
is necessary. Over reli ance on this func-
tion may lead to an accident resulting 
death or serious injury.

The RCTA function operates when all of the 
following conditions are met:
●The BSM main switch is on.
●The shift lever is in R.
●The vehicle speed is less than approxi-
mately 5 mph (8 km/h).
●The approaching vehicle speed is 
between approximately 5 mph (8 km/h) 
and 18 mph (28 km/h).
■Conditions under which the RCTA func-
tion 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*

: Depending on the conditions, detection  of a vehicle and/or object may occur.
■Conditions under which the RCTA func-
tion may not function correctly
●The RCTA 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
