How to Adjust the Headlights in a Ford Focus. Unload any extra cargo you don't carry in your Ford Focus on a daily basis. Inflate the tires to the proper air pressure and replicate any other normal conditions for your daily driving. Park the car (with the emergency brake dispensed) on a level surface 5 to 10 feet away from a wall or garage door. Turn on your headlights and locate the center of the trajectory path on the wall. Mark the center point for each headlight on the wall with masking tape. Put your Ford Focus in reverse and back up to a distance of 25 feet from the wall. Park the car, set your emergency break and turn off the engine. Bounce the car gently to settle the suspension. Pop the hood and locate the headlight aim-turn screws. Ford locates these on top of the headlight unit.
