INSTALLATION
CAUTION: Do not touch the glass of HID or halogen
lamps with fingers or other possibly oily surface.
Reduced lamp life will result.
HALOGEN HEADLAMP
(1) Place the headlamp in the lamp socket, being
careful to align the lamp with the socket index.
(2) Place lamp socket into the headlamp housing
(Fig. 15).
(3) Connect the lamp electrical connector (Fig. 16).
(4) Install the rubber boots/seals protecting the
lamp from the elements.
(5) Install the headlamp unit (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING
-
EXTERIOR/HEAD-
LAMP UNIT - INSTALLATION).

(IF EQUIPPED) - LOW BEAM
HEADLAMP
(1) Place the headlamp into the lamp opening of
headlamp unit, being careful to align the lamp to the
indexes.
Make sure the slots on the igniter are lined up. If
not, use a small screwdriver to align them (Fig. 20).
(2) Place the igniter on the HID lamp. Do not at
this time connect the igniter electrical connector. It
will make it unable to twist the igniter to the closed
position.
(3) Twist the igniter clockwise to close/lock it into
place.
(4) Position the igniter electrical connector and
firmly snap into place (Fig. 21).
(5) Install the rubber boots/seals protecting the
lamp/igniter from the elements.
(6) Install the headlamp unit (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING
-
EXTERIOR/HEAD-
LAMP UNIT - INSTALLATION).

STANDARD PROCEDURE - HEADLAMP UNIT
ALIGNMENT
HEADLAMP UNIT ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.
(3) Verify proper tire inflation.
(4) Clean headlamp lenses.
(5) Verify that luggage area is loaded as the vehi-
cle is routinely used.
(6) Vehicles equipped with automatic load leveling
suspension should be driven normally for approxi-
mately 5 km (3 miles) before attempting a proper
headlamp unit alignment.
(7) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.

ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 7.62 meters (25 ft.) away from front
of headlamp lens (Fig. 22).
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall.
(3) Rock vehicle side-to-side three times and allow
suspension to stabilize.
(4) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(5) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for
up/down adjustment reference.
HEADLAMP UNIT ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp centerline ± 50 mm (2 in.). Horizontal aim is
preset and can not be adjusted. The high beam pat-
tern should be correct when the low beams are
aligned properly. To adjust headlamp vertical align-
ment, rotate adjustment screw to achieve the speci-
fied low beam cut-off location (Fig. 23).
