HEADLIGHT ASSEMBLY (for HID Headlight) ADJUSTMENT

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.

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.

PREPARE FOR HEADLIGHT AIMING

*a 25 m or 3 m

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.
- 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 m or 3 m

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.
- Create a 10 m (33 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 (33 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).
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.
Draw a vertical line down the center of the screen (V line).
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.
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.

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.

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.
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).

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.
  
  CAUTION:
  
  Do not disconnect the HID high voltage connector for the bulb when performing this 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.
  
  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 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.):

4. for 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.
  
  If the alignment distance is 10 m (32.8 ft.):
  
  The low beam cutoff line should be within 94 mm (3.70 in.) and 285 mm (11.2 in.) below the H line as well as 99 mm (3.89 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 28 mm (1.10 in.) and 85 mm (3.34 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 10 m (32.8 ft.):

5. except China:
  
  Turn on the high beams and check if the center of intensity for each high beam matches the preferred center of the 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 174 mm (6.87 in.) above and 248 mm (9.79 in.) below the H line as well as 497 mm (1.63 ft.) left or right of the V LH or V RH line.

6. for China:
  
  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 on each side have separate reflectors, it is necessary to check and adjust the aim separately for both.

ADJUST HEADLIGHT AIMING

Adjust the aim vertically:

Text in Illustration
*A	w/ Night View System	*B	w/o Night View System
*1	Vertical Aiming Screw	*2	Horizontal and Vertical Aiming Screw
*3	Screwdriver	-	-

Adjust the aim of each headlight to 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

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 bulbs, headlight unit and headlight unit reflector installation.
The headlight aim moves up when turning the aiming screw counterclockwise, and moves down when turning the aiming screw clockwise.
Turn the vertical aiming screw and horizontal aiming screw the same amount when making adjustments.
