Autolamp delay system (if equipped)
If your vehicle is equipped with autolamps, you can set the delay time to
keep the headlights on for up to three minutes after the key is turned
off. The delay time is set to 20 seconds at the factory, but the delay 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 off 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 on position.
5. Turn the key back to the off
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.
Fog lamp control
The headlamp control also operates
the fog lamps. The fog lamps can be
turned on when the headlamp
control is in the
or
positions and the high beams are
not turned on.
Pull the headlamp control towards
you to turn the fog lamps on. The
fog lamp indicator light
will
illuminate.

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.

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.
