4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.
5. Locate the vertical adjuster on
each headlamp. Use a number 2
Phillips screwdriver to turn the
adjuster either counterclockwise or
clockwise in order to adjust the
vertical aim of the headlamp. The
upper edge of the light pattern
should touch the horizontal
reference line.
6. Repeat Steps 3–5 for the other
headlamp.
7. Close the hood and turn off the lamps.
HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT 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.
These are examples of acceptable condensation:
• Presence of thin mist (no streaks, drip marks or droplets).
• Fine mist covers less than 50% of the lens.
