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 foreach headlamp. Adjust the aim
by using a 4 mm wrench to turn
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. Usea4mm
wrench, turning 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.
TURN SIGNAL CONTROL
• Push down to activate the left
turn signal.
• Push up to activate the right turn
signal.
