CAUTION / NOTICE / HINT

Tech Tips

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. PREPARE VEHICLE FOR HEADLIGHT AIM ADJUSTMENT


    1. Prepare the vehicle:


      • Ensure 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.

      • A004IJ8

        Vehicles with manual headlight beam level control systems should be adjusted to "0" (w/ Headlight Leveling).

      *a 25 or 3 m (82 or 9.84 ft.)
      *b 90°

      Prepare the vehicle (except 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 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.

      • 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.)

      *a 10 or 3 m (32.8 or 9.84 ft.)
      *b 90°

      Prepare the vehicle (for 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 the 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 (6.6 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. Set the screen as shown in the illustration (except China).

      *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 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 manufacturer's name 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 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 headlight bulbs).

  3. 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.

      Tech Tips

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

    2. Start the engine.

    3. Turn on the headlights and check if the cutoff line for each low beam matches the preferred cutoff line in the illustration (except China).

      *a V LH Line *b V RH Line
      *c H Line *d Preferred Cutoff Line
      *e Point A - -

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

        The low beam cutoff line should be within 48 mm (1.89 in.) and 698 mm (27.4 in.) below the H line as well as 248 mm (9.79 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 (0.227 in.) and 83 mm (3.29 in.) below the H line as well as 29 mm (1.17 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 (9.79 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.

    4. Turn on the headlights and check if the cutoff line for each low beam matches the preferred cutoff line in the illustration (for China).

      *a V LH Line *b V RH Line
      *c H Line *d Point A

      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 10 m (32.8 ft.):

        The horizontal line of the low beam cutoff line should be within 69 mm (2.72 in.) and 206 mm (8.11 in.) below the H line.

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

        The horizontal line of the low beam cutoff line should be within 21 mm (0.827 in.) and 62 mm (2.44 in.) below the H line.

      • If the alignment distance is 10 m (32.8 ft.):

        Point A of the low beam cutoff line should be within 169 mm (6.66 in.) left and 349 mm (13.7 in.) right of the V LH or V RH line.

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

        Point A of the low beam cutoff line should be within 50 mm (1.97 in.) left and 104 mm (4.09 in.) right of the V LH or V RH line.

    5. Turn on the high beams and check if the center of intensity for each high beam matches the center of intensity in the illustration (for China).

      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 10 m (32.8 ft.):

        The high beam center of intensity should be on the H line or within 33 mm (1.29 in.) below the H line.

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

        The high beam center of intensity should be on the H line or within 10 mm (0.393 in.) below the H line.

      • If the alignment distance is 10 m (32.8 ft.):

        The high beam center of intensity for the headlight assembly LH should be within 169 mm (6.66 in.) left and 349 mm (1.14 ft.) right of the V LH line.

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

        The high beam center of intensity for the headlight assembly LH should be within 50 mm (1.99 in.) left and 104 mm (4.12 in.) right of the V LH line.

      • If the alignment distance is 10 m (32.8 ft.):

        The high beam center of intensity for the headlight assembly RH should be within 349 mm (1.14 ft.) left or right of the V RH line.

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

        The high beam center of intensity for the headlight assembly RH should be within 104 mm (4.12 in.) left or right of the V RH line.

  4. ADJUST HEADLIGHT AIMING


    1. Remove any covers necessary to access the headlight adjusters.

      *1 Aiming Screw A

      Adjust the aim vertically:

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

      Note


      • The high beam light and low beam light aim move in the diagonal direction when aiming screw A is turned. Remember the turning direction and the number of turns of aiming screw A to correct the horizontal position in the next step.

      • 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.

    3. A004I1IE04

      *1 Aiming Screw B

      Turn aiming screw B the same number of turns and in the same direction as aiming screw A.

      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 light and the high beam light 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 bulb, headlight unit, and headlight unit reflector installation.
