1. Park your car on a level surface facing a wall or garage door about 10 feet away.
2. Turn on the headlights.
3. Open the hood of your car.
4. Locate the headlight adjustment screws. On the E350, there are two screws for each headlight, one for vertical adjustment and one for horizontal adjustment.
5. Use a Phillips head screwdriver to turn the adjustment screws. Turning the screw clockwise will raise the headlight, while turning it counterclockwise will lower the headlight.
6. Continue adjusting the headlights until they are aimed correctly. The headlights should be aimed so that the top of the beam is level with the center of the headlights on the wall or garage door.
7. Close the hood of your car and turn off the headlights.
If you are having trouble adjusting the headlights, you may want to take your car to a qualified mechanic.
