PARKING ASSIST MONITOR SYSTEM DETAILS


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Rear Television Camera Assembly

    • Captures images of the area behind the vehicle.

    • The parking assist guide lines that are calculated based on signals from the steering sensor are superimposed on the captured image. Then, the image is sent to the radio and display receiver assembly as video signals.

    • When the luggage compartment door is open, superimposing of parking assist guide lines is canceled and only the captured image is sent as video signals.
    Radio and Display Receiver Assembly Displays images of the area behind the vehicle sent from the rear television camera assembly using the multi-display.
    Park/Neutral Position Switch Assembly Sends an R shift position signal to the ECM.
    ECM Sends an R shift position signal to the rear television camera assembly.
    Steering Sensor Detects the angle of the steering wheel and sends the resulting signals to the rear television camera assembly.

    2. Multi-display


      1. Modes for the parking guide line function can be switched on the back camera guide line setting screen selected from the settings screen.

        A01HWTS

      2. The parking guide line function consists of estimated course line display mode, parking assist guide line display mode and distance guide line display mode. The initial (default) setting for perpendicular parking is estimated course line display mode.

      3. In each mode, fixed guide lines appear superimposed on a view of the area behind the vehicle. These guide lines can be used to assist the driver while backing up the vehicle.

        1. Move the shift lever to R.

        2. An image appears on the multi-display as illustrated below.

          A01HWRH

        3. Turn the steering wheel so that the estimated course lines are within the parking space, and back up carefully.

          A01HWGM

        4. 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 guide lines and the painted lines of the parking space.

        5. 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.

          A01HWOM

    2. Parking Assist Guide Line Display Mode (Perpendicular Parking)


      1. To use estimated course line display mode in perpendicular parking when parking the vehicle in a parking space, perform the following procedure:


        1. Move the shift lever to R.

        2. An image appears on the multi-display as illustrated below.

          A01HWAP

        3. Back up the vehicle and stop at the position in which the parking assist guide line comes in contact with the left side of the intended parking position.

        4. Turn the steering wheel fully to the right and back up the vehicle.

          A01HWSY

        5. Continue backing up the vehicle until the vehicle is parallel to the painted lines.
