The vehicle should be properly prepared as
follows:
•
The vehicle should be placed so the
headlamps are 25 ft. (7.6 m) from a light
colored wall or other flat surface.
•
The vehicle must have all four tires on a level
surface which is level all the way to the wall
or other flat surface.
•
The vehicle should be placed so it is
perpendicular to the wall or other flat surface.
•
The vehicle should not have any snow, ice, or
mud on it.
•
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
•
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver's seat.
•
Tires should be properly inflated.
•
The spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle's
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.

the distance.
