ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Vertical aim adjustment
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 of the headlamp bulb center from the ground and
mark an 8 foot (2.4 meter) horizontal reference line on the vertical wall
or screen at this height.
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
To see a clearer light pattern for adjusting, you may want to block the
light from one headlamp while adjusting the other.

For vehicles with halogen headlamps:
On the wall or screen you will
observe a flat zone of high intensity
light located at the top of the right
hand portion of the beam pattern. If
the top edge of the high intensity
light zone is not at the horizontal
reference line, the headlamp will
need to be adjusted.
For vehicles with HID headlamps:
There is a distinct cut-off (change
from light to dark) in the left
portion of the beam pattern. The
top edge of this cut-off should be
positioned 2 inches (5 cm) below
the horizontal reference line.
4. Locate the vertical adjuster on
each headlamp. Using a Hex head
driver, turn the adjuster either
clockwise (to adjust down) or
counterclockwise (to adjust up). The
horizontal edge of the brighter light
should touch the horizontal
reference line.
5. Close the hood and turn off the lamps.
HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NON-ADJUSTABLE.
CHANGING A BULB
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.

Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
Replacing headlamp bulbs

Note:If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
1. Make sure that the headlamp control is in the off position.
