Oldsmobile 1998 Aurora

If you find that the headlamp aiming needs adjustment,
follow these steps:
Start with the vertical headlamp aim. Don't try to adjust
the horizontal aim first. Adjustment screws can be
turned with
an E8 Torx@socket or T15 Torx screwdriver.
1. Check the vertical aim for each headlamp. The
vehicle must be parked on a level surface. Turn the
vertical aiming screw until the bubble in the level is
centered at
0 (zero).

2. After the vertical aim is correct, check the horizontal
aim for each headlamp and adjust as necessary. Turn
the horizontal aiming screw until the pointer is lined
up with the
0 (zero).
3. Visually recheck the vertical aim, to make sure it is
still correct after the horizontal aim adjustment.
Readjust,
if necessary.
