How do you align headlights on 2000 Volvo s40?

To align the headlights on a 2000 Volvo S40, park the car on a level surface facing a wall about 25 feet away. Measure the height from the ground to the center of the headlight and mark this height on the wall. Turn on the headlights and adjust the beams so that they are centered at the mark and slightly below it, ensuring they are aimed straight ahead and not to the left or right. Use the adjustment screws located on the back of the headlights to make the necessary changes.
