Toyota Camry Owner's Manual (2023): Changing the buzzer sounds volume - Intuitive parking assist

The buzzer volume can be changed on the multi-information display when the engine switch is in IGNITION ON mode.

â– The system can be operated when

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

â– If "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 object may not be detected. If the sensor thaws out, the system should return to normal.

â– If "Parking Assist Unavailable" is displayed on the multi-information display

Water may be continuously flowing over the sensor surface, such as in a heavy rain. When the system determines that it is normal, the system will return to normal.

â– Sensor detection information

• The sensor's detection areas are limited to the areas around the vehicle's front and rear bumpers.
• 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.
  • Detection may be impossible if static objects draw too close to the sensor.
  • There will be a short delay between static object detection and display (warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 1.0 ft. (30 cm) before the display is shown and the warning buzzer 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 sound of this system due to the buzzers of other systems.

â– Objects which the system may not be properly detected

The shape of the object may prevent the 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 objects
• Tall objects with upper sections projecting outwards in the direction of your vehicle

â– Situations in which the system may not operate properly

Certain vehicle conditions and the surrounding environment may affect the ability of a sensor to correctly detect objects. Particular instances where this may occur are listed below.

• There is dirt, snow, water drops 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 displayed abnormally, or objects, such as a wall, may not be detected.
• 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.
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which produce ultrasonic waves are near the vehicle
• A sensor is coated with a sheet of spray or heavy rain.
• If objects draw too close to the sensor.
• When a pedestrian is wearing clothing that does not reflect ultrasonic waves (ex. skirts with gathers or frills).
• When objects that are not perpendicular to the ground, not perpendicular to the vehicle traveling direction, uneven, or waving are in the detection range.
• Strong wind is blowing
• When driving in inclement weather such as fog, snow or a sandstorm
• When an object that cannot be detected is between the vehicle and a detected object
• If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front of the vehicle or runs out from the side of the vehicle
• If the orientation of a sensor has been changed due to a collision or other impact
• When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
• If the front of the vehicle is raised or lowered due to the carried load
• If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunctioning
• When a tire chains or compact spare tire is used

â– Situations in which the system may operate even if there is no possibility of a collision

In some situations, such as the following, the system may operate even though there is no possibility of a collision.

• When driving on a narrow road

• When driving toward a banner, flag, low-hanging branch or boom barrier (such as those used at railroad crossings, toll gates and parking lots)
• When there is a rut or hole in the surface of the road
• When driving on a metal cover (grating), such as those used for drainage ditches
• When driving up or down a steep slope
• If a sensor is hit by a large amount of water, such as when driving on a flooded road
• There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
• A sensor is coated with a sheet of spray or heavy rain
• When driving in inclement weather such as fog, snow or a sandstorm
• When strong winds are blowing

• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which produce ultrasonic waves are near the vehicle
• If the front of the vehicle is raised or lowered due to the carried load
• If the orientation of a sensor has been changed due to a collision or other impact
• The vehicle is approaching a tall or curved curb
• Driving close to columns (H-shaped steel beams, etc.) in multi-story parking garages, construction sites, etc.
• If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunctioning
• On an extremely bumpy road, on an incline, on gravel, or on grass

• When a tire chains or compact spare tire is used

WARNING

â– Cautions regarding the use of the system

There is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle' surroundings and driving safely.

â– To ensure the system can operate properly

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 damage the sensors, and always keep them clean.
• Do not attach a sticker or install an electronic component, such as a backlit license plate (especially fluorescent type), fog lights, fender pole or wireless antenna near a radar sensor.
• Do not subject the surrounding area of the sensor to a strong impact. If subjected to an impact, have the vehicle inspected by your Toyota dealer.

  If the front or rear bumper needs to be removed/installed or replaced, contact your Toyota dealer.

• Do not modify, disassemble or paint the sensors.
• Do not attach a license plate cover.
• Keep your tires properly inflated.

â– 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.

• Failing to observe the warnings above.
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

â– 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.
• When using an automatic car wash, disable the intuitive parking assist
