It is important that the headlights are aimed correctly to avoid blinding oncoming drivers and to ensure optimal visibility on the road. Headlights should be checked for proper aim every 12 months and whenever a new headlight is installed or front end body work is performed. The procedure outlined provides a temporary adjustment until a properly equipped shop can make the necessary changes. These models have only one adjustment screw on the back of the headlight housing, which adjusts the vertical aim; horizontal aiming is not adjustable. To adjust the headlights, find an open area with a blank wall and a level floor. Position masking tape vertically on the wall in line with the vehicle centerline and the centerlines of both headlights, and add a horizontal tape line in reference to the centerline of all headlights, ideally with the vehicle parked just a few inches away. The vehicle should be parked 25 feet from the wall, sitting level, with the gas tank half-full and no unusually heavy load. For low beam adjustment, position the high intensity zone two inches below the horizontal line by turning the adjustment screws. With the high beams on, the high intensity zone should be vertically centered just below the horizontal line. It may not be possible to achieve perfect aim for both high and low beams, so prioritize low beams for driver safety. Have the headlights adjusted by a dealer service department as soon as possible.
