LEXUS PARKING ASSIST-SENSOR SYSTEM


  1. OPERATION


    1. Depending on the detection distance and the detection area, the sound pattern of the No. 1 clearance warning buzzer will vary.

    2. When a sensor malfunction is detected or a sensor is frozen or dirty, the buzzer sounds 5 times according to the following timing:

    3. The ultrasonic sensors are divided into 2 groups: a front section group (front corners and front center) and a rear section group (rear corners and rear center). If multiple ultrasonic sensors detect obstructions at the same time, the No. 1 clearance warning buzzer sounds as follows, in accordance with the detection distance and detection area of each group:

      Buzzer Sound Pattern ON/OFF Time (msec.)
      Detection Distance Short (*B) Middle (*B) Long (*B) Longest (*B) Not detected
      Short (*A) Timing 1 Timing 2 Timing 2 Timing 2 Continuous Sound

    4. Clearance Warning Buzzer Mute Function


      1. When a sensor detects an obstacle with the shift lever not in P or R, the buzzer can be temporarily muted using the buzzer mute switch in the multi-display assembly.

      2. The mute function is canceled if the vehicle speed reaches a certain level.
