■Conditions under which the BSM function may not function correctly
●The BSM 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 surround-
ing area • When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area onthe 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 wi th only a small gap between each vehicle
• 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 vehiclethat 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 yourvehicle
• As your vehicle starts from a stop, a vehicle 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 vehiclein an adjacent lane is far away from your vehicle
• When towing a trailer (vehicles with towing package) • When items such as a bicycle carrier are installed on 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 unnecessarily detecting a vehicle and/or object mayincrease in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround- ing 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 vehicle traveling in a lane other than the adjacent 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 a bicycle carrier or other accessory is installed to the rear of the vehicle
• When towing a trailer (vehicles with towing package)

■RCTA icon display (if equipped)
When a vehicle approaching from the right or left at the rear of the vehicle is
detected, the following will be displayed on the audio system screen.

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 RCTA function is only a supplementary fu nction which alerts the driver that a vehi- cle is approaching from the right or left at th e rear of the vehicle. As the RCTA function
may not function correctly under certain conditions, the driver’s own visual confirma- tion of safety is necessary. Over reliance on this function may lead to an accidentresulting death or serious injury.

• Immediately after the RCTA function is turned on • Immediately after the engine is started with the RCTA function on
●Instances of the RCTA function unnecessarily detecting a vehicle and/or object mayincrease in the following situations:
• When a vehicle passes by the side of your vehicle
• 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 ofthe vehicle, is short
• When backing out of a shallow angle park- ing spot
• When the sensors cannot detect a vehicle due to obstructions
• When the parking space faces a street and
vehicles are being driven on the street

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle, the
buzzer sounds continuously: Appr oximately 35 cm (1.2 ft.).
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a long tone, followed by fast beeps.
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection range
of the sensors. Note that the sensors cannot detect obstacles that areextremely close to the vehicle.
The range of the sensors may change depending on the shape of the objectetc.

■The Lexus parking assist-sensor can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode. • The shift lever is in other than P.
• The vehicle speed is less than about 10 km/h (6 mph). (At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode. • The shift lever is in other than P or R.
• The vehicle speed is less than about 10 km/h (6 mph).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode. • The shift lever is in R.
■Lexus parking assist-sensor display
●Vehicles with a Lexus Display Audio system : When an obstacle is detected while the Lexus parking assist monitor is in use, the warning indicator will appear in the upperpart of the screen even if the display setting has been set to off.
●Vehicles with a navigation system: If the Lexu s parking assist-sensor display is set to on, detected objects will also be displayed on the panoramic view monitor. For details, refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an obstacle. Particular instances where this may occur are listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.) • The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected. • The sensor is covered in any way.• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass. • The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, airbrakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity. • The sensor is coated with a sheet of spray or heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb. • In harsh sunlight or intense cold weather.• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor. • A non-genuine Lexus suspension (low ered suspension etc.) is installed. • People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape, signs and other objects may be judged by a sensor to be closer than they are.
