Tighten headlamp fasteners to 22 ft‑lb or 30 N·m
with rubber gasket, once correct visual aim is
achieved.
1. Place vehicle on a level surface
25 feet (7.62 m) in front of a matte‑white
screen, such as a garage door. The screen
should be perpendicular both to the ground
and to the vehicle centerline.
2. The vehicle should be equipped for normal
operation. The snowplow blade should be in
place and in raised position. Below are steps

inspection. Before checking beam aim, the
inspector will:
a. Remove ice or mud from under fenders.
b.
Set tire inflation pressures to the values
specified on vehicle information label.
c. Check springs for sag or broken leaves.
d. See that there is no load in the vehicle
other than the driver and ballast as
specified in the Power Match selection
system.
e. Check functioning of any automatic
vehicle leveling systems and specific
manufacturer's instructions pertaining to
vehicle preparation for headlamp aiming.
f. Clean lenses.

switching.
