AIMING 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 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.

BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
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.
