Sensor detection display, obstacle distance

■ Distance display Sensors that detect an obstacle will illuminate continuously or blink.

*1: The images may differ from those shown in the illustrations.
*2: Multi-information display
*3: Audio system screen
*4: Lexus Display Audio or navigation system (8-inch display) screen

■ Buzzer operation and distance to an object A buzzer sounds when the sensors are operating.

• The buzzer sounds faster as the vehicle approaches an object.

  When the vehicle comes within the following distance of the object, the buzzer sounds continuously: Approximately 1.2 ft. (35 cm).

• When 2 or more objects are detected simultaneously, the buzzer system responds to the nearest object. If one or both come within the above distances, the beep will repeat a long tone, followed by fast beeps.

Detection range of the sensors

1. Approximately 3.3 ft. (100 cm)
2. Approximately 4.9 ft. (150 cm)
3. Approximately 2.0 ft. (60 cm)
4. RX450h:
   Approximately 2.0 ft. (60 cm)
   RX450hL:
   Approximately 2.1 ft. (66 cm)

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

The range of the sensors may change depending on the shape of the object, etc.

Navigation system screen

1. The buzzer sounds volume can be adjusted.
2. On or off can be selected for intuitive parking assist display.
3. Both the front or rear center sensors display and tone indication can be set.

■ The intuitive parking assist can be operated when

• Front corner sensors:
  • The power switch is in ON mode.
  • The shift lever is in 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)

• Front center sensors:
  • The power switch is in ON mode.
  • The shift lever is in other than P or R.
  • The vehicle speed is less than about 6 mph (10 km/h).
• Rear corner and rear center sensors:
  • The power switch is in ON mode.
  • The shift lever is in R.

■ Intuitive parking assist display

• Vehicles with a Lexus Display Audio system/navigation system (8-inch display): When an object is detected while the Lexus parking assist monitor or panoramic view monitor is in use, the warning indicator will appear in the upper part of the screen even if the display setting has been set to off.
• Vehicles with a navigation system (12.3-inch display): If the intuitive parking assist 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 object. Particular instances where this may occur are listed below.
  • There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this problem.)
  • 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.
  • When a sensor or the area around a sensor is extremely hot or cold.
  • 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, air brakes 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 bumper or sensor receives a strong impact.
  • If the vehicle is significantly tilted.
  • 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 objects draw too close to the sensor.
  • 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.

• The shape of the object may prevent a 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 obstacles
  • Tall obstacles with upper sections projecting outwards in the direction of your vehicle
• 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 impossible.
  • Objects may not be detected if they are too close to the sensor.
  • There will be a short delay between object detection and display. Even at slow speeds, there is a possibility that the object will come within the sensor's detection areas before the display is shown and the buzzer sounds.
  • Thin posts or objects lower than the sensor 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 displayed 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 object may not be detected. If the sensor thaws out, the system should return to normal.

■ If "Parking Assist Malfunction" 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 your Lexus dealer.

■ Certification

For vehicles sold in Canada

This ISM device complies with Canadian ICES-001.

Cet appareil ISM est conforme a la norme NMB-001 du Canada.

■ Customization Some functions can be customized.

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 possibly cause an accident.

• Do not use the sensor at speeds in excess of 6 mph (10 km/h).
• 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 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 vehicle is equipped with a fender pole or wireless antenna.
• 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 sensor malfunction, etc. Have the vehicle checked by your Lexus dealer.

• The intuitive parking assist operation display flashes, and a buzzer sounds when no obstacles are detected.
• If the area around a sensor collides with something, or is subjected to strong impact.
• If the bumper collides with something.
• If the display shows continuously without beeping, except when the buzzer mute switch has been turned on.
• If a display error occurs, first check the sensor.

  If the error occurs even if there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.

WARNING

■ 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 malfunctioning.

• When using a high pressure washer to wash the vehicle, do not spray the sensors 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 sensor to malfunction.
