Lights AIMING THE HEADLAMPS The headlamps on your vehicle are properly aimed at the assembly plant. If your vehicle has been in an accident the alignment of your headlamps should be checked by a qualified service technician. Headlamp vertical aim adjustment 1. Park the vehicle on a level surface approximately 7.6 meters (25 feet) from a vertical wall or screen directly in front of it. • (1) Eight feet • (2) Center height of lamp to ground • (3) Twenty five feet • (4) Horizontal reference line 2. Measure the height from the center of your headlamp to the ground and mark a 2.4 meter (8 foot) horizontal reference line on the vertical wall or screen at this height (a piece of masking tape works well). The center of the lamp is marked by a 3.0 mm circle on the headlamp lens. 3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. 4. On the wall or screen you will observe a light pattern with flat edges at the top of the beam pattern. If the flat edges are not at the horizontal reference line, the beam will need to be adjusted. 39 2004 04- Mustang (mus) Owners Guide (post-2002-fmt) USA English (fus)
