AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed before leaving the
assembly plant. If your vehicle is involved in an accident or if you have
problems fixing the alignment of your headlamps, have them checked by
a qualified service technician.
Headlamp aim adjustment
The headlamps are designed to be mechanically aimed, but can also be
aimed visually by doing the following:
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.

5. Locate the vertical adjuster for
each headlamp. Adjust the aim by
turning the adjuster control either
clockwise (to adjust down) or
counterclockwise (to adjust up).
6. In addition to the horizontal line
marked in step 2, a pair of vertical
lines (5) must be marked at the
center line of the headlamps on the
wall or screen.
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 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.

BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to assure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
