•(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.
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.
4. Locate the vertical adjuster on
each headlamp. Using a Phillips #2
screwdriver or 13 mm
wrench/socket, 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.

BULB REPLACEMENT
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.
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 ensure 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.

Replacing the low beam headlamps
Note:The low beam headlamp is the outboard lamp.
Note:Never hold a bulb by the glass. This is particularly valid for
halogen bulbs as the intensity of the light may be reduced if the hands
touch the bulb. If the glass has been handled, clean it with alcohol.
1. Remove the bulb cover.
2. Turn the bulb holder
counterclockwise and remove it.
3. Disconnect the electrical connector.
4. Reverse the procedure to install the new bulb
Replacing the high beam headlamps
Note:The high beam headlamp is the inboard lamp.
Note:Never hold a bulb by the glass. This is particularly valid for
halogen bulbs as the intensity of the light may be reduced if the hands
touch the bulb. If the glass has been handled, clean it with alcohol.
