Headlights must be aimed correctly to avoid blinding oncoming drivers and reducing visibility. It is recommended to check the aim every 12 months and whenever a new headlight is installed. The simplest method involves using masking tape, a blank wall, and a level floor. The tape should be vertically on the wall in reference to the vehicle centerline and the centerlines of both headlights, with a horizontal tape line in reference to the centerline of all the headlights. The adjustment should be made with the vehicle parked 25 feet from the wall. For low beam adjustment, the high-intensity zone should be positioned two inches below the horizontal line and two inches to the side of the headlight vertical line. The adjustment can be made by turning the vertical adjusting screw. With high beams on, the high-intensity zone should be vertically centered just below the horizontal line. Some 2002 models have a horizontal adjustment screw, but later models do not offer adjustment for the horizontal plane. Prioritize the proper aim of the low beams.

The vertical adjusting screw can raise or lower the beam, while the horizontal adjusting screw can move the beam left or right.
