Operation Check [11/2018 - ]

  1. SELF-DIAGNOSIS SYSTEM 
    1. When a malfunction occurs in the intuitive parking assist system or the system cannot be used, a warning is displayed on the multi-information display (on the combination meter assembly) and the meter buzzer sounds to inform the driver that the system is unavailable.

  2. DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION 
    NOTE:

    The following measurement and inspection will be performed with the shift lever in a position other than P. Be sure to apply the parking lever and depress the brake pedal firmly to prevent the vehicle from moving.

    1. Turn the power switch on (IG).
    2. Turn the combination switch assembly (clearance sonar main switch) on.
    3. Detection range measurement:
      1. Move the shift lever according to the table below.
        Measurement Area Shift Lever Position
        Front Corner Sensor (front corner ultrasonic sensor) In any position other than P
        Front Center Sensor (front center ultrasonic sensor) In any position other than P or R
        Rear Corner Sensor (rear corner ultrasonic sensor) R
        Rear Center Sensor (rear center ultrasonic sensor)
      2. Move a 60 mm (2.4 in.) diameter pole near each sensor to measure its detection range. When measuring the Longest-range detection of the front center sensor and the rear center sensor, use a wall or equivalent.
        NOTE:

        These detection ranges are applicable when positioning the 60 mm (2.4 in.) diameter pole parallel or perpendicular to the ground. The detection range varies depending on the measuring method and type of obstacle (such as walls).

        HINT: 

        Have an assistant move the pole.
