2. Measure the height from the center of
your headlamp (indicated by a 3.0
millimeter 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).
Note:
To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Switch 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.
For halogen or LED headlamps:
On
the wall or screen you will observe a
light pattern with a distinct horizontal
edge toward the right. If this edge is not
at the horizontal reference line, you will
need to adjust the beam so the edge
is at the same height as the horizontal
reference line.

5. Locate the vertical adjuster on each
headlamp. Use a #2 Phillips
screwdriver to turn the adjuster either
counterclockwise or clockwise in order
to adjust the vertical aim of the
headlamp.
6. Repeat Steps 3 through 7 to adjust the
other headlamp.
7.
Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
CHANGING A BULB
WARNING
Handle a halogen headlamp bulb
carefully and keep out of children’s
reach. Grasp the bulb only by its
plastic base and do not touch the glass.
The oil from your hand could cause the
bulb to break the next time the headlamps
are operated.
Note:
If the bulb is accidentally touched,
clean it with rubbing alcohol before
installing it.
