HEADLIGHT ASSEMBLY(for Halogen Headlight and LED Headlight) ADJUSTMENT

CAUTION / NOTICE / HINT

PROCEDURE

1. PREPARE VEHICLE FOR HEADLIGHT AIMING ADJUSTMENT

   
   

   1. Prepare the vehicle:

      
      

      • 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.

      • 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.

      • Bounce the vehicle at the corners up and down to stabilize the suspension.

2. PREPARE FOR HEADLIGHT AIMING

   
   

   1. except China:

      Prepare the vehicle.

      
      
      • 

        *a	90°
        *b	25 m or 3 m

        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 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.

      • 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 headlights) 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. for China:

      Prepare the vehicle.

      
      
      • 

        *a	90°
        *b	10 m or 3 m

        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 (32.8 ft.) distance between the vehicle (center marks of the low beam) 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 10 m (32.8 ft.) between the vehicle (center marks of the low beam headlights) 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.)

   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.

      
   7. 

      *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.

      
      

      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 low beam center marks of the low beam headlights.

      2. V LH Line and 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 marks of the low beam).

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.

      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 headlight, cover the low beam headlight.

   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

4. ADJUST HEADLIGHT AIMING

   
   
   1. 

      *a	Horizontal Aiming
      *b	Vertical Aiming

      Using a screwdriver, adjust the aim.

      Adjust the aim of each headlight so that it is within 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 headlight assembly, headlight unit assembly and No. 1 headlight bulb 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.
