    PREPARE FOR HEADLIGHT AIMING


    1. A0008RPE01
      Table 1.
      *1 25 m or 3 m

      Prepare the vehicle (except Taiwan and China):


      • 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 a 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.

      • 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 (headlight bulb center) 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.)

    2. A0008RPE04
      Table 2.
      *1 10 m or 3 m

      Prepare the vehicle (for Taiwan and China):


      • 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 a wall.

      • Create a 10 m (32.8 ft.) distance between the vehicle (headlight bulb center) 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 (32.8 ft.) between the vehicle (headlight bulb center) 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. A00091LE01

      Set the screen as shown in the illustration (except Taiwan and China).

      Tip:

      • Stand the screen perpendicular to the ground.

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

    6. A00091LE03

      Set the screen as shown in the illustration (for Taiwan and China).

      Tip:

      • Stand the screen perpendicular to the ground.

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

    7. A0008NXE60

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

      Table 3. Text in Illustration
      *a V LH Line
      *b V Line
      *c V RH Line
      *d H Line
      *e Ground
      Tip:

      • 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.


      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 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).

    INSPECT HEADLIGHT AIMING


    1. Cover the headlight or disconnect the connector of 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.

      Tip:

      When checking the aim of the high beam, cover the low beam or disconnect the connector.

    2. Start the engine.

    ADJUST HEADLIGHT AIMING


    1. A0003W6E02

      Adjust the aim vertically:

      Table 4. Text in Illustration
      *1 Aiming Screw A

      Adjust the aim of each headlight to the specified range by turning each aiming screw A 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.

      Tip:

      • 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 headlight aim, check bulb, headlight assembly and headlight unit reflector installation.

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

      • Confirm the direction of rotation of the aiming screw by observing it while it is being adjusted. Due to the position of the screwdriver, the direction of rotation of the adjusting screw can be different than the direction of rotation of the screwdriver being used to adjust it.
