Vertical aim adjustment
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 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 #2
Philips head 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. Repeat Steps 3–5 for the other
headlamp.
7. Close the hood and turn off the lamps.
