• Tall obstacles with upper sections projecting outwards in the direction of

sounds. Even if the vehicle is moving at low speeds, the vehicle may come
close to the obstacle before the buzzer sounds.
● Obstacles that are lower than the sensor or thin may not be detected when
the vehicle comes close, even after they are detected once.
● When the audio system (if equipped) or air conditioning system is used, the
buzzer may not be heard due to the sound of music or the fan.

If the buzzer sounds when there is no obstacle, clean the sensors with soft
cloth. If the buzzer does not stop after cleaning the sensor, contact your
Toyota dealer.
