1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters)
away.
•
(1) 8 feet (2.4 meters)
•
(2) Center height of lamp to
ground
•
(3) 25 feet (7.6 meters)
•
(4) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 mm circle on the lens) to the ground and mark an 8 foot
(2.4 meter) horizontal reference line on the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light from that lamp
hits the wall.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam will need to be adjusted so the edge
is at the same height as the horizontal reference line.
5. Locate the vertical adjuster on
each headlamp, then use a Phillips
#2 screwdriver to turn the adjuster
either counterclockwise (to adjust
down) or clockwise (to adjust up)
aligning the upper edge of the light
pattern up to the horizontal line.
6. HORIZONTAL AIM IS NOT
REQUIRED FOR THIS VEHICLE
AND IS NON-ADJUSTABLE.
7. Repeat Steps 3–5 for the other headlamp.
8. Close the hood and turn off the lamps.
