1. Prepare vehicle for checking beam aim as follows:

B. Place vehicle on level surface.
^ Vehicle must be level. If necessary, pads may be used on uneven floors.
C. Stop all other work on vehicle.
D. Close doors.
E. Rock vehicle sideways to stabilize suspension.
NOTICE: Horizontal aim of headlamp capsule (Chevrolet) or headlamp (Pontiac) must be done first. Adjusting vertical aim first will result in incorrect headlamp aim.
