246 Maintenance On the wall or screen, you will observe a flat zone of high intensity light located at the top of the right hand portion of the beam pattern. If the top edge of the high intensity light zone is not at the horizontal reference line, the headlamp will need to be adjusted. 4. Locate the vertical adjuster on each headlamp. 5. Then use a 7 mm Allen wrench or a Phillips screwdriver to adjust the vertical aim of the headlamp. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS NON-ADJUSTABLE. 6. Close the hood and turn off the lamps. CHANGING A BULB Lamp Assembly Condensation Exterior lamps are vented to accommodate normal changes in pressure. Condensation can be a natural by-product of this design. When moist air enters the lamp assembly through the vents, there is a possibility that condensation can occur when the temperature is cold. When normal condensation occurs, a thin film of mist can form on the interior of the lens. The thin mist eventually clears and exits through the vents during normal operation. Clearing time may take as long as 48 hours under dry weather conditions. These are examples of acceptable condensation: • Presence of thin mist (no streaks, drip marks or droplets). • Fine mist covers less than 50% of the lens. 2013 05+ Mustang (197) Owners Guide gf, 3rd Printing USA (fus)
