PREPARING THE VEHICLE FOR HEADLAMP AIM OR INSPECTION
Rotate aimer positioning system (pointer) to front of aimer. Move aimer so that positioning pointer is at center of headlight beam. The
pointer can be stored as shown with dashed lines in illustration, when not in use.
Note: There are several ways to determine the center of the headlight beam. If your headlight has a clear lens and you can see the bulb, it
is generally located at the center. Some headlight lenses have a small dot in the lens that indicates the center. Many light beams have a
“dark spot” in the center of the beam, this can be easily found by placing a cloth over the light and turning on the headlights.
Place the aimer in front of one headlamp at a distance between 10 to 14 in. (25 to 35 cm). Most beam patterns are clearest if the optical
lens is about 12” from the lamp surface.
