How do you adjust headlight beams on 2001 Malibu?

To adjust the headlight beams on a 2001 Chevy Malibu, park the car on a level surface approximately 25 feet from a wall. Turn on the headlights and mark the center of the beam on the wall with tape. Locate the adjustment screws on the headlight assembly—one for vertical adjustment and one for horizontal. Use a screwdriver to turn the screws until the beam is aligned with the marked tape, ensuring the lights shine at a height and angle that does not blind oncoming drivers.
