HEADLIGHT ASSEMBLY(for HID Headlight) ADJUSTMENT

CAUTION / NOTICE / HINT

Tech Tips


  • Use the same procedure for the RH and LH sides.

  • The procedure listed below is for the LH side.

  • It is possible that a bulb is incorrectly installed, affecting headlight aim. Bulb installation should be considered prior to performing the adjustment procedure.

PROCEDURE


  1. VEHICLE PREPARATION FOR HEADLIGHT AIMING ADJUSTMENT


    1. Prepare the vehicle:

      Tech Tips


      • Make sure that there is no damage to the body around the headlights.

      • Fill the fuel tank.

      • Make sure that the oil is filled to the specified level.

      • Make sure that the coolant is filled to the specified level.

      • Inflate the tires to the appropriate pressure.

      • Unload the trunk and vehicle, ensuring that the spare tire, tools and jack are in their original positions.

      • Have a person of average weight (75 kg, 165 lb) sit in the driver seat.

  2. PREPARATION FOR HEADLIGHT AIMING (Using a screen)

    *a 25 m or 3 m

    1. Prepare the vehicle.


      • Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the headlights can be observed and above which it cannot.

      • Place the vehicle at a 90° angle to the wall.

      • Create a 25 m (82 ft.) distance between the vehicle (headlight bulb center) and the wall.

      • Make sure that the vehicle is on a level surface.

      • Bounce the vehicle up and down to settle the suspension.

        Note

        A distance of 25 m (82 ft.) between the vehicle (headlight bulb center) and the wall is necessary for proper aim adjustment. If unavailable, secure a distance of exactly 3 m (9.84 ft.) for the check and adjustment. (The target zone will change with the distance, so follow the instructions in the illustration.)

    2. Prepare a piece of thick white paper approximately 2 m (6.56 ft.) (height) x 4 m (13.1 ft.) (width) to use as a screen.

    3. Draw a vertical line down the center of the screen (V line).

    4. Set the screen as shown in the illustration.

      Tech Tips


      • Stand the screen perpendicular to the ground.

      • Align the V line on the screen with the center of the vehicle.

      *b V Line
      *c V RH Line
      *d H Line
      *e Ground

      Draw base lines (H, V LH and V RH lines) on the screen as shown in the illustration.

      Tech Tips


      • The base lines differ for "low beam inspection" and "high beam inspection".

      • Mark the headlight bulb center marks on the screen. If the center mark cannot be observed on the headlight, use the center of the headlight bulb or the name of the manufacturer marked on the headlight as the center mark.


      1. H Line (Headlight height):

        Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the headlight bulb center marks of the low beam headlights.

      2. V LH Line, V RH Line (Center mark position of the left-hand (LH) and right-hand (RH) headlights):

        Draw 2 vertical lines so that they intersect the H line at each center mark (aligned with the center of the low beam headlight bulbs).

  3. INSPECT HEADLIGHT AIMING


    1. Start the engine.

    2. Turn on the headlight and check if the cutoff line matches the preferred cutoff line in the following illustration.

      Tech Tips


      • Since the low beam light and the high beam light on each side have separate reflectors, it is necessary to check and adjust the aim separately for both.

      • The illustration is for LHD vehicles. RHD vehicles are the opposite of the illustration.

      • If the alignment distance is 25 m (82 ft.):

        The low beam cutoff line should be within 48 mm (1.89 in.) and 698 mm (2.29 ft.) below the H line as well as 249 mm (9.80 in.) left or right of the V LH or V RH line.

      • If the alignment distance is 3 m (9.84 ft.):

        The low beam cutoff line should be within 6 mm (0.236 in.) and 84 mm (3.30 in.) below the H line as well as 30 mm (1.18 in.) left or right of the V LH or V RH line.

      • If the alignment distance is 25 m (82 ft.):

        The horizontal line of the preferred low beam cutoff line is 249 mm (9.80 in.) below the H line and point A of the preferred low beam cutoff line is on the V LH or V RH line.

      • If the alignment distance is 3 m (9.84 ft.):

        The horizontal line of the preferred low beam cutoff line is 30 mm (1.18 in.) below the H line and point A of the preferred low beam cutoff line is on the V LH or V RH line.

    3. Turn on the high beams and check if the center of intensity for each high beam matches the center of intensity in the illustration.

      Tech Tips


      • Since the low beam light and the high beam light on each side have separate reflectors, it is necessary to check and adjust the aim separately for both.

      • If the alignment distance is 25 m (82.0 ft.):

        The high beam center of intensity should be within 175 mm (6.88 in.) above and 249 mm (9.80 in.) below the H line as well as 497 mm (1.63 ft.) left or right of the V LH or V RH line.

      • If the alignment distance is 3 m (9.84 ft.):

        The high beam center of intensity should be within 21 mm (0.827 in.) above and 30 mm (1.18 in.) below the H line as well as 60 mm (2.36 in.) left or right of the V LH or V RH line.

  4. ADJUSTMENT HEADLIGHT AIMING

    *1 Vertical Aiming
    *2 Horizontal Aiming
    *3 Screwdriver

    1. Using a screwdriver, adjust the aim.

      Adjust the aim of each headlight to the specified range by turning each aiming screw with a screwdriver.

      Note

      The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it, and then retighten it so that the final turn of the screw is in the clockwise direction.

      Tech Tips


      • The low beam and high beam headlight are a unit. Adjusting the aim on the low beam to the correct position should also result in the high beam adjustment being correct.

      • If it is not possible to correctly adjust headlight aim, check the bulb, headlight unit and headlight unit reflector installation.

      • The headlight aim moves up when turning the vertical aiming screw clockwise, and moves down when turning the vertical aiming screw counterclockwise. The headlight aim moves right when turning the horizontal aiming screw clockwise, and moves left when turning the horizontal aiming screw counterclockwise.
