Lights AIMING THE HEADLAMPS The headlamps on your vehicle are properly aimed at the assembly plant. If your vehicle has been in an accident the alignment of your headlamps should be checked by your authorized dealer. Vertical aim adjustment 1. Park the vehicle directly in front of a wall or screen on a level surface, approximately 25 feet (7.6 meters) away. • (1) 8 feet (2.4 meters) • (2) Center height of lamp to ground • (3) 25 feet (7.6 meters) • (4) Horizontal reference line 2. Measure the height from the center of your headlamp to the ground and mark an 8 foot (2.4 meter) horizontal reference line on the vertical wall or screen at this height (a piece of masking tape works well). The center of the lamp is marked by a 3.0 mm circle on the headlamp lens. 3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. Cover the left-hand headlamp with an opaque cloth. 4. On the wall or screen you will observe a light pattern with a distinct horizontal edge of high intensity light towards the right. If this edge is not at the horizontal reference line, the beam will need to be adjusted. 36 2006 Mariner (mrn) Owners Guide (post-2002-fmt) USA (fus)
