PARKING ASSIST MONITOR SYSTEM DETAILS


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Rear Television Camera Assembly Captures images of the area behind the vehicle and outputs video signals to the navigation receiver assembly.
    Navigation Receiver Assembly Displays the image of the area behind the vehicle sent from the rear television camera assembly using the multi display. The image is combined with the parking assist guide lines that are calculated based on signals from the spiral with sensor cable sub-assembly (steering angle sensor).
    Park/Neutral Position Switch Assembly Sends a shift position signal to the navigation receiver assembly.
    Steering Sensor Detects the angle of the steering wheel and sends the resulting signals to the navigation receiver assembly.
    Combination Meter Assembly Transmits the vehicle speed signal to the navigation receiver assembly.

          A01FCKN

        6. When the rear of the vehicle is within the parking space, turn the steering wheel in order to equalize the gap between the left and right sides of the vehicle width extension lines and the painted lines of the parking space.

        7. When the vehicle width extension guide lines and the painted lines of the parking space are parallel, straighten the steering wheel and then carefully back up until the entire vehicle is within the parking space.

          A01FCIJ

    3. Parallel Parking Assist Mode


      1. To use parallel parking assist mode to park the vehicle in the parking space, perform the following procedure:


        1. Stop the vehicle parallel to the road or the curb, at a side-to-side clearance of about 1 m (3.3 ft.) from the parked vehicle, approximately one-half car length forward of the parked vehicle.
