Lights AIMING THE HEADLAMPS Your vehicle is equipped with an aerodynamic headlamp system. The aerodynamic headlamps can only be aimed in the vertical direction (up/down) using the procedure following. The headlamps on your vehicle are properly aimed at the assembly plant and should not normally need adjustment. Vertical aim adjustment The headlamps on your vehicle can only be vertically adjusted. Your vehicle does not require horizontal aim adjustments. To adjust the headlamps: 1. Park the vehicle directly in front of a wall or screen on a level surface, approximately 25 feet (7.6 meters) away. • (1) 8 feet (2.4 meters) • (2) Center height of lamp to ground • (3) 25 feet (7.6 meters) • (4) Horizontal reference line 2. Measure the height from the center of your headlamp (indicated by a 3.0 mm circle on the lens) to the ground and mark an 8 foot (2.4 meter) horizontal reference line on the vertical wall or screen at this height (a piece of masking tape works well). 3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. Cover one of the headlamps so no light from that lamp hits the wall. 4. On the wall or screen you will observe a light pattern with a distinct horizontal edge towards the right. If this edge is not at the horizontal reference line, the beam will need to be adjusted so the edge is at the same height as the horizontal reference line. 90 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
