time may be changed by following the steps below (Steps 1 through 6
must be done within 10 seconds):
1. Turn the key to the 1 (LOCK)
position.
2. Rotate the headlamp control to
the autolamp position.
3. Rotate the headlamp control to
the OFF position.
4. Turn the key to the 3 (RUN)
position.
5. Turn the key back to the
1 (LOCK) position.
6. Turn the headlamp control to the autolamp position (the headlights
should turn on).
7. Turn the headlamp control to the OFF position when the desired
delay time (up to 3 minutes) has been reached.

operation.
Move the control to the full upright
position, past detent, to turn on the
interior lamps.
Rotate to full down position (past
detent) to prevent interior lamps
from illuminating when the doors are opened.
Note:If the battery is disconnected, discharged, or a new battery is
installed, the dimmer switch requires re-calibration. Rotate the dimmer
switch from the full dim position to the full Dome/ON position to reset.
This will ensure that your displays are visible under all lighting
conditions.

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.
