Headlamp Aiming Procedure

^ To correct the horizontal aim use the adjusting screw located on the outer side of the headlamps.
^ To correct the vertical aim by use the adjusting screw located in the top center of the headlamps.
^ Use a specific aiming area in a darkened location. Ensure that the aiming area meets the followings:
- The area used must accommodate the vehicle with a space of 7.6 m (25 ft) left over.
- Measure the additional 7.6 m (25 ft) from the face of the headlamps to the front of the screen.
- The floor that the vehicle rests on is level with the bottom of the screen.
- If the floor is not level, then compensate for the unlevel floor.




^ Ensure that the aiming screen meets the following:
- The screen (2) is 1.5 m (5 ft) high and 3.6 m (12 ft) wide.
- The surface of the screen (2) is a matte white.
- The screen (2) is well shaded from outside light.
- The screen (2) is correctly adjusted to the floor on which the vehicle stands.
- The following items are present:
^ A vertical center line (2)
^ A horizontal center line (4) for the center line of the lamps
^ A horizontally adjustable horizontal tape (3)
^ 2 laterally adjustable vertical tapes (9)

IMPORTANT: Adjust the horizontal lines or tape (3) on the screen (2) for each vehicle that you inspect. Vehicles of the same model and year may have different standing height for the headlamps.

^ Make provisions for moving the aiming screen in order to align the aiming screen parallel with the rear axle of the vehicle.
- This will allow for a horizontal line (4) drawn to pass through the center point between the two headlamp capsules.
- The horizontal line (4) will be drawn perpendicular from the center line of the screen (2).
^ Once you set up the screen (2) in a permanent location, paint a reference line (7) on the floor. The reference line (7) will identify the proper location of the headlamps when the headlamps are being aimed.
^ If a regular commercial aiming screen is not available, the screen may consist of the following items:
^ A vertical wall that has a clear, uninterrupted area.
Ensure that the area is 1.8 m (6 ft) high and 3.6 m (12 ft) wide
^ Ensure that the area is finished with a washable, nongloss white paint.
