TOYOTA PARKING ASSIST-SENSOR SYSTEM PRECAUTION

  1. PRECAUTION FOR TOYOTA PARKING ASSIST-SENSOR SYSTEM

    Tip:

    • In very cold weather, the sensor may not detect obstacles.

    • If the malfunction display appears, visually check the sensor first. If the sensor is free of foreign matter but the malfunction display remains, the sensor may have a malfunction.

    1. Under the following conditions, the detection function may not operate properly:

      1. The sensor is covered with foreign matter, such as mud or snow (detection function returns to normal if sensor is cleaned).

      2. The sensor is frozen (detection function returns to normal when the sensor is defrosted).

      3. A hand is blocking the sensor.

    2. The detection range may be affected by the following conditions:

      1. The sensor is covered with foreign matter, such as mud or snow.

      2. The vehicle is in a very hot or cold area.

    3. Under the following conditions, a detection error may occur:

      1. Driving on a bumpy road, on an unpaved road or in tall grass.

      2. Things that transmit ultrasonic waves, such as other vehicle horns or sonar systems, motorcycle engines, or large vehicle air brakes, are near the vehicle.

      3. It is raining heavily or water is sprayed on the sensor.

      4. The vehicle is extremely tilted.

      5. The vehicle is equipped with a commercial fender pole or a wireless mechanism antenna.

      6. The sensor is covered with foreign matter, such as mud or snow.

      7. The vehicle is moved forward or backward towards high curbs or objects that are perpendicular to the ground.

      8. A sensor is sprayed with high pressure water or steam.

      9. A towing hitch is mounted on the vehicle.

    4. The sensor cannot detect the following objects.

      1. Thin objects, such as wires and ropes.

      2. Materials that easily absorb ultrasonic waves, such as cotton, snow, etc.

      3. Objects with sharp edges.

      4. Short objects.

      5. Tall objects with a projected upper part.

    5. Other notices:

      1. The sensor cannot detect objects directly under the bumper (the sensor may detect low objects and thin poles, and then lose track of the objects).

      2. Be aware that the detection range of this system is limited. In certain conditions, some objects may not be detected. Always make sure to check all around the vehicle when driving or parking.

      3. The sensor may be unable to detect obstacles that are too close to the sensor.

      4. The sensor may be unable to detect obstacles if it is dropped or subjected to a strong impact, especially on the membrane.
