Park your BMW 535i 30 feet away from a closed garage door.
Shine the headlights onto the garage door.
Open the hood and turn the vertical adjustment screw until the center of the headlight beams are positioned at the bottom of the door--where the door meets the ground.
Turn the lateral adjustment screws on both headlights until the headlight beams overlap by about half (40 percent to 50 percent).Adjusting the headlights on your BMW 535i must be done if you replace the headlight housing assemblies with housings that did not come pre-adjusted from the factory. A misaligned headlight can cause your headlight beams to blind oncoming traffic and, in turn, cause a car accident. And misaligned headlights mean you can't see the road ahead of you as well as possible. The 535i uses two adjustment screws to adjust the headlights. The vertical adjustment screw is located at the front of the grille, while the lateral (horizontal) adjustment screw is located in the engine compartment next to the fender--it looks like a long piece of white plastic with a Phillips-head on the end of it.
