■Conditions under which the RCTA function will not detect a vehicle
The RCTA function is not designed to dete ct the following types of vehicles and/or objects:
●Vehicles approaching from directly behind
●Vehicles backing up in a parking space next to your vehicle
●Guardrails, walls, signs, parked vehi cles 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 function may not function correctly
●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 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 a vehicle is approaching at high speed • When towing a trailer (vehicles with towing package)
●Vehicles that the sensors cannot detect due toobstructions
• When backing up on a slope with a sharp change in grade

• 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

■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.

3784-5. Using the driving support systems
RX350/RX200t_EE_OM48F32E
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten- tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves • Sharply-angled objects• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi- cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor. • There will be a short delay between obst acle detection and display. Even at slow speeds, there is a possibility that the obstacl e will come within the sensor’s detection
areas before the display is shown and the buzzer sounds. • Thin posts or objects lower than the sens or may not be detected when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of the air conditioning system.
■If “Clean Parking Assist Sensor” is di splayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from the sensor, the system should return to normal. Also, due to the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may not be detected. If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfun ction” is displayed on the multi-information display
Depending on the malfunction of the sensor , the device may not be working normally. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
■Customization
Some functions can be customized. ( P. 376,740)
WARNING
■When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driven safely and possibly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check the areas surrounding the vehicle (especially the sides of the vehi-cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
