Headlight Assembly (For Halogen Headlight) Adjustment

Prepare the vehicle:

1. Ensure that the vehicle has no damage or deformation around the headlights.
   
2. Fill the fuel tank.
   
3. Make sure that the oil is filled to the specified level.
   
4. Make sure that the coolant is filled to the specified level.
   
5. Inflate the tires to the appropriate pressure.
   
6. Unload the trunk and vehicle, ensuring that the spare tire, tools, and jack are in their original positions.
   
7. Have a person of average weight (55 kg, 121 lb) sit in the driver seat.
   

Prepare the vehicle according to the following conditions:

1. Move the vehicle to a location that is sufficiently dark so that the headlight cutoff line can be visually checked. The cutoff line is an imaginary plane below which headlight light is projected and above which light is not projected.
   
2. Move the vehicle to a level surface.
   
3. Point the front of the vehicle at a wall. The wall must be perpendicular to the surface that the vehicle is on.
   
4. Position the vehicle 10 m (32.8 ft.) from the wall.
   
5. Push down on the vehicle several times to settle the suspension. Do not damage the suspension.
   

HINT:

A distance of 10 m (32.8 ft.) between the vehicle and the wall is necessary for proper aim adjustment. If unavailable, secure a distance of exactly 3 m (9.8 ft.). View the part of the illustration below applicable to the distance from the vehicle to the wall.

Prepare a piece of thick white paper that is approximately 2 m (6.6 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).

Set the screen as shown in the illustration.

HINT:

1. Stand the screen perpendicular to the ground.
   
2. 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.

HINT:

1. The base lines differ for ''lo-beam inspection'' and ''hi-beam inspection''.
   
2. 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 headlights being inspected.
   

2. V LH line, V RH line (center mark position of LH and RH headlights being inspected):
   Draw two vertical lines so that they intersect the H line at each center mark.
   

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.

NOTICE:

Do not keep the headlight covered for more than 3 minutes. The headlight lens is made of synthetic resin, and may easily melt or be damaged due to heat.

HINT:

When checking the aim of the hi beam bulb, cover the lo beam bulb or disconnect the connector.

Start the engine.

Turn on the headlights and make sure that the cutoff line is within the specified area shown in the illustration.

Adjust the vertical headlight aim into the specified range by turning aiming screw A with a screwdriver.

HINT:

1. Perform lo beam aim adjustment. Adjusting the aim of the lo beam to the correct position should also result in the hi beam adjustment being correct.
   
2. The headlight aim moves down when turning the aiming screw clockwise, and moves up when turning the aiming screw counterclockwise.
   

NOTICE:

If the screw is tightened too much, loosen it and then retighten it so that the final turn of the screw is in the clockwise direction.

Adjust the horizontal headlight aim into the specified range by turning aiming screw B with a screwdriver.

HINT:

Perform lo beam aim adjustment. Adjusting the aim of the lo beam to the correct position should also result in the hi beam adjustment being correct.

NOTICE:

If the screw is tightened too much, loosen it and then retighten it so that the final turn of the screw is in the clockwise direction.
