First remove the chrome rim around the headlight with one screw. Second the adjustments should be four spring loaded screws on the left, right, top and bottom of the headlight.
Pretty much all cars have adjustable headlights. Most consists of a set of screw with spring around them. Turn in different ones in increments until the lights are aimed correctly.
Have someone who know how they are adjusted to this. Nothing is worse then going towards a car and their headlights are out of focus and killing your eyes. Check your owners manual first.
