How do you adjust the headlights on a Renault Megane II?

To adjust the headlights on a Renault Megane II, first park the car on a level surface about 10-15 feet from a wall. Turn on the headlights and mark the center of the light beam on the wall. Use a screwdriver to adjust the vertical and horizontal screws near the headlight assembly until the beams align with the marked points. Finally, check the alignment by turning off the headlights and ensuring they are symmetric.
