Lights switch from the full dim position to the full dome/on position to reset. This will ensure that your displays are visible under all lighting conditions. 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 of the headlamp bulb center from 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). 3. Turn on the low beam headlamps to illuminate the wall or screen and open the hood. To see a clearer light pattern for adjusting, you may want to block the light from one headlamp while adjusting the other. 4. On the wall or screen you will observe an area of high intensity light. The top of the high intensity area should touch the horizontal reference line, if not, the beam will need to be adjusted using the next step. 57 2009 Sable (mgo) Owners Guide, 2nd Printing USA (fus)
