ALIGNMENT CHECK

1 Park vehicle on level ground or pavement facing wall or screen 25 feet (7.6 meters) away.

Measure distance between center of headlight and ground.

Cut two 2-in. x 2-in. (5-cm x 5-cm) boards to length 12 in. (30.5 cm) longer than distance

between center of headlight and ground.

Hold or tape boards upright against side of vehicle.

Sight along upper inner edge of boards and mark wall or screen at point in alignment with

boards. Measure straight down 12 in. (30.5 cm) from this point and make another mark. This

is the reference point, which represents left-hand edge of vehicle at same height above ground

as center of headlight.

Draw horizontal line approximately 125 in. (318 cm) long, 27-1/2 in. (70 cm) below and

extending to the right of reference point.

Draw two vertical lines crossing horizontal line: one at 11 in. (28 cm) and the other at 118 in.

(300 cm) to the right of reference point.

Turn on service drive headlights and dim to low beam.

Check that center spot (brightest light) of each low beam is centered on aiming lines.

Align headlights as required.

11 If headlight alignment is correct, turn off service drive headlights.
