Turning intuitive parking assist on/off

Intuitive parking assist can be enabled/disabled on the multi-information display as following:

1. Press or of meter control switches and select .

2. Press or of meter control switches and select "PKSA".

3. Press or of meter control switches, select , and then press to select the desired setting (on/off).

When ON (enable) is selected, the Intuitive parking assist indicator comes on.

When switched to OFF (disable) and the Intuitive parking assist is deactivated, the system will not reactivate if it is not switched to ON again from the screen of the multi-information display (Will not reactivate via power switch operations).

■The intuitive parking assist can be operated when

• The power switch is in ON mode.
• Intuitive parking assist function is on.
• The vehicle speed is less than about 6 mph (10 km/h).
• A shift position other than P is selected.

■Setting the buzzer volume The buzzer volume can be adjusted on the multi-information display.

■Muting the buzzer sound

• To mute the buzzer sound
  The buzzer can be temporarily muted by pressing of the meter control switches while an obstacle detection display is shown on the multi-information display.
• To cancel the mute
  Mute will be automatically canceled in the following situations.
  • When the shift position is changed
  • When the vehicle speed has reached or exceeded approximately 6 mph (10 km/h) with the shift lever in D
  • When the intuitive parking assist is turned off once and turned on again
  • When the power switch is turned off once and turned to ON mode again
  • When a sensor is malfunctioning

■Intuitive parking assist display When an obstacle is detected while the Lexus parking assist monitor is in use, the warning indicator will appear in the upper corner of the screen even if the display setting has been set to off.

■If "Parking Assist Unavailable" or "Parking Assist Unavailable 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 obstacle may not be detected.

If the sensor thaws out, the system should return to normal.

■If "Parking Assist Malfunction Visit Your Dealer" 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.

■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 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.
• 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 vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• 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 (lowered 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.

• The shape of the obstacle may prevent a sensor from detecting it. Pay particular attention 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 vehicle

• 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 obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle 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.

■Customization Some functions can be customized.

WARNING

■When using the intuitive parking assist Observe the following precautions.

Failure 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.

NOTICE

■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.

■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.

Sensor detection display, obstacle distance

■ Detection range of the sensors

1. Approximately 3.3 ft. (100 cm)
2. Approximately 4.9 ft. (150 cm)
3. Approximately 1.9 ft. (65 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.

■ Distance display Sensors that detect an obstacle will illuminate continuously or blink. (As the distance to the object becomes less than 1.0 ft. (30 cm), the distance segments may blink.)

*1: The images may differ from that shown in the illustrations.
*2: Automatic buzzer mute function is enabled.
*3: The distance segments will blink slowly.

■ 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 approximately 1.0 ft. (30 cm) of the obstacle, the buzzer sounds continuously.

• 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.
• Automatic buzzer mute function: After a buzzer begins sounding, if the distance between the vehicle and the detected object does not become shorter, the buzzer will be muted automatically. (However, if the distance between the vehicle and object is 1.0 ft. (30 cm) or less, this function will not operate.)
