7. On the wall or screen, locate the high intensity area of the beam
pattern. The left edge of the high intensity area should be even with the
vertical line corresponding to the headlamp under adjustment. If the left
edge of the high intensity area is not even with the vertical line, follow
the next step to adjust it.
8. Locate the horizontal adjuster (2) for each headlamp. Turn it
clockwise or counterclockwise, to place the left edge of the high
intensity area even with the vertical line corresponding to the headlamp
under adjustment.
VERTICAL AIM ADJUSTMENT (AERODYNAMIC HEADLAMPS)
The headlamps on your vehicle can only be vertically adjusted. Your
vehicle does not require horizontal aim adjustments.
To adjust the headlamps:
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 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.
