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	Headlight Center Mark

        w/o Adaptive High Beam System:

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

        w/ Adaptive High Beam System:

        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.

      Note

      A distance of 25 m (82 ft.) between the vehicle (center marks) 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	Headlight Center Mark

        w/o Adaptive High Beam System:

        Create a 10 m (32.8 ft.) distance between the vehicle (center marks of the headlight) and the wall.

      • 

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

        w/ Adaptive High Beam System:

        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.

      Note

      A distance of 10 m (32.8 ft.) between the vehicle (center marks) 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.

      *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 center marks on the screen.

      
      

      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 center marks.

      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 headlight).

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.

   2. Start the engine.

   3. except China:

      
      

      1. 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.

         • 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 (0.24 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.

           

      2. 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 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 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.

4. ADJUST HEADLIGHT AIMING

   
   
   1. 

      *a	Aiming Screw B
      *b	Aiming Screw A

      Using a screwdriver, adjust the aim.

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

      Note

      
      

      • At this time, count and record the number of rotations and directions.

      • 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 the headlight aim, check the headlight assembly and headlight unit installation.

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