Maintenance and care 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. 2. Measure the height from the center of your headlamp to the ground and mark an 2.4 meters (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 distinct line of high intensity light. If this is not centered on the horizontal reference line, the beam will need to be adjusted. 5. Locate the vertical adjuster on each headlamp, then use a 6 mm wrench or screwdriver to turn the adjuster either counterclockwise (to adjust up) or clockwise (to adjust down) centering the light on the horizontal reference line. 6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS NON-ADJUSTABLE. 7. Close the hood and turn off the lamps. CLEANING AND CARING FOR YOUR VEHICLE Refer to the Customer Assistance chapter for a list of Ford-approved cleaners, polishes and waxes. 176
