Headlamp Aiming Screen

If you are using a screen, ensure that the following criteria is met:
^ The screen is at least 1.52 m (5 ft) high by 3.66 m (2 ft) wide
^ The screen has a matte white surface well shaded from ambient light
^ The screen is properly adjusted to the floor on which the vehicle stands
^ The screen is movable
^ The screen can be aligned parallel with the rear axle of the vehicle

Position the screen in order to ensure that a horizontal line will pass an equal distance midway between the two headlamps.

Ensure that the screen provides the following features:
^ A vertical centerline
^ Two laterally adjustable vertical tapes
^ One vertically adjustable horizontal tape

If a regular commercial aiming screen is not available, use a wall having a clear uninterrupted area at least 1.83 m (6 ft) high by 3.66 m (12 ft) wide. Ensure that the surface is finished with a washable no-gloss white paint.

After the aiming screen is set up and located, paint or tape a reference line on the floor 7.62 m (25 ft) from the screen. Park the vehicle with the front of the headlamps directly over the reference line.
