VERTICAL AND HORIZONTAL AIM ADJUSTMENT (SEALED BEAM
HEADLAMPS)
The headlamps on your vehicle are intended to be aimed using
mechanical aimers. If mechanical aimers are used and the cross-car sight
line is in any way blocked, set the legs of the universal adaptor all to the
same setting, such that the cross-car sight line is no longer blocked, per
the instructions for the brand of mechanical aimer used. You can also
aim the headlamps visually using the procedure below.
To adjust the headlamps:
1. Park your vehicle on a level surface about 25 feet (7.6 meters) away
from a vertical plain surface (3). Check your headlamp alignment at
night or in a dark area so that you can see the headlamp beam pattern.
•
(1) 8 feet (2.4 meters)
•
(2) Center height of lamp to
ground
•
(3) 25 feet (7.6 meters)
•
(4) Horizontal reference line
•
(5) Center of headlamps
•
(6) Center line of the vehicle
2. The center of the headlamp is
marked either on the lens (a circle
or cross marker) or on the bulb shield, internal to the lamp (mark or
feature). Measure the height from the center of your headlamp to the
ground (2) and mark an 8 foot (2.4 meter) long horizontal line on the
wall or screen (1) at this height (masking tape works well).
3. Turn on the low beam headlamps
and open the hood.
4. Locate the high intensity area of
the beam pattern and place the top
edge of the intensity zone even with
the horizontal reference line (4). If
the top edge of the high intensity
area is not even with the horizontal
line, follow the next step to adjust
it.
