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 from the
center of your headlamp 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). The center of the lamp is
marked by a 3.0 mm circle on the headlamp lens.
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover the left-hand headlamp with an opaque cloth.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge of high
intensity light towards the right. If
this edge is not at the horizontal
reference line, the beam will need to
be adjusted.
5. Locate the vertical adjuster on
the headlamp, then turn the
adjuster either clockwise (to adjust
up) or counterclockwise (to adjust
down) aligning the upper edge of
the light pattern to the horizontal
line.
6. Move the opaque cloth to cover
the right-hand headlamp and repeat
Steps 4 and 5 for the left-hand
headlamp.

Interior lighting battery saver
The interior lamps will automatically extinguish after 10 minutes when
the ignition key is in the off/lock position, a door has been left open or
the interior lamp controls are in the on position.
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 dealer for service if any of the above conditions of
unacceptable moisture are present.
