How do you adjust headlamps on Jaguar XJ6 2001?

To adjust the headlamps on a 2001 Jaguar XJ6, first park the vehicle on a level surface about 10-25 feet from a wall or garage door. Use a Phillips screwdriver to locate the vertical and horizontal adjustment screws, which are typically found on the back of the headlamp assembly. Turn the screws clockwise or counterclockwise to raise or lower the beam and adjust the horizontal alignment until the light pattern is centered and at the correct height. Finally, check the alignment by turning on the headlights and ensuring the beams are properly positioned.
