HEADLIGHT ASSEMBLY(for Triple Beam Headlight) ADJUSTMENT

PROCEDURE


  1. PREPARE VEHICLE FOR HEADLIGHT AIM ADJUSTMENT


    1. Prepare the vehicle:


      • Make sure there is no damage or deformation 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.

      • Sit a person of average weight (75 kg, 165 lb) in the driver's seat.

    *a 25 m or 3 m

    1. except China:

      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.

        *b High Beam Center Mark

        Create a 25 m (82 ft.) distance between the vehicle (center marks of the low beam) and the wall.

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

      • Position the front wheels straight ahead.

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

        Note

        A distance of 25 m (82 ft.) between the vehicle (center marks of the low beam) and the wall is necessary for proper aim adjustment. If sufficient space is not available, secure a distance of exactly 3 m (9.84 ft.) to allow for checking and adjustment of headlight aim. (The size of the target zone will change with the distance, so follow the instructions in the illustration).

      for China:

      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.

        *a Low Beam Center Mark
        *b High Beam Center Mark

        Create a 10 m (33 ft.) distance between the vehicle (center marks of the low beam) and the wall.

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

      • Position the front wheels straight ahead.

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

        Note

        A distance of 10 m (33 ft.) between the vehicle (center marks of the low beam) and the wall is necessary for proper aim adjustment. If sufficient space is not available, secure a distance of exactly 3 m (9.84 ft.) to allow for checking and adjustment of headlight aim. (The size of the target zone will change with the distance, so follow the instructions in the illustration).

    3. 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.

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

    5. except China:

      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.

    6. for China:

      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.

      *a V LH Line
      *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 center marks on the screen. If the center mark cannot be observed on the headlight, use the center of the headlight.


      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 center marks of the low beam headlights.

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

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

  3. INSPECT HEADLIGHT AIMING


    1. Cover the headlight on the opposite side to prevent light from the headlight that is not being inspected from affecting the headlight aiming inspection.

      Note

      Do not keep the headlight covered for more than 3 minutes. The headlight lens is made of synthetic resin, which may melt or be damaged due to excessive heat.

      Tech Tips

      When checking the aim of the high beam, cover the low beam.

    2. Start the engine.

    3. except China:

      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 are a unit, if the aim on the low beam is correct, the high beam should also be correct. However, check both beams just to make sure.

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

  4. ADJUST HEADLIGHT AIMING

      Text in Illustration
      *a Vertical Aiming Screw
      *b Horizontal Aiming Screw

      Using a screwdriver, adjust the aim.

      Adjust the aim of each headlight so that it is within the specified range by turning 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


      • Since the low beam light and the high beam light are a unit, if the aim on the low beam is correct, the high beam should also be correct. However, check both beams just to make sure.

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

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

      • for LH Side:

        The headlight aim moves right when turning the aiming screw clockwise, and moves left when turning the aiming screw counterclockwise.

      • for RH Side:

        The headlight aim moves right when turning the aiming screw counterclockwise, and moves left when turning the aiming screw clockwise.
