TOYOTA PARKING ASSIST-SENSOR SYSTEM


  1. DESCRIPTION


    1. A Toyota parking assist-sensor system is used, depending on the model.

    2. The Toyota parking assist-sensor system uses ultrasonic sensors to detect any obstacles at the corners, or the rear of the vehicle.

    3. The Toyota parking assist-sensor system then informs the driver of the approximate distance between the sensors and the obstacles as well as their positions by displaying them on the multi-information display in the combination meter or the multi-display* and by sounding a clearance warning buzzer.

    4. The Toyota parking assist-sensor system is controlled by the clearance warning ECU.

    5. The operating condition of each Toyota parking assist-sensor system differs according to its installed position as shown in the table below:

      *: Optional Equipment

      Installation Position Operating Condition
      Ultrasonic Sensor (Front Corner LH and RH)

      • Power source is IG-ON.

      • Shift position is in any position other than P.

      • Vehicle speed is approximately 10km/h (6 mph) or less. The sensor stops operating when the vehicle speed is 13 km/h (8 mph) or more, and starts operating when the vehicle speed decreases to below 9 km/h (5.6 mph).

      • Back sonar or clearance sonar switch is ON.

      Ultrasonic Sensor (Rear Corner LH and RH)

      Ultrasonic Sensor (Rear Center LH and RH)

      • Power source is IG-ON.

      • Shift position is R.

      • Back sonar or clearance sonar switch is ON.

    *c Approx.150cm (59 in.) *d Approx.170cm (67 in.)
    *e Approx.60cm (23.6 in.) - -

    1. These detection ranges are applicable when positioning a 60mm (0.2ft.) diameter pole parallel or perpendicular to the ground. The ranges vary depending on the measuring method and type of obstacle.
