Inspection

If part of the HUD image is distorted or is not at the driver's eye level, use the Kia Diagnostic System (KDS) to perform calibration.

  1. Calibration is required:

    • After replacing the head-up display

    • If the image is distorted after windshield replacement (windshield with built-in double-layer film for vision removal).

    • When removing/installing or replacing the main crash pad mounted with the HUD.

    • When the HUD image installation position is not within the driver's field of view, resulting in an out-of-focus image.

  2. Calibration Items

    No Image Calibration Functions Calibration Cases
    1 Clockwise/counterclockwise calibration of the image center is possible.
    2 Smile: Calibrate vertically to the center.
    3 Tilt (up/down): Calibrate the vertical tilt.
    4 Tilt (left/right): Calibrate the horizontal tilt.
    5 Parallel Compensation

    7 Initialization: Return to the previous state before calibration.

  3. Calibration Procedure

    1. Park the vehicle on a level surface for accurate adjustment.

    2. Make sure there are no foreign objects on the windshield.
