OPERATION - TURN SIGNAL SYSTEM
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Multi-function switch
²Body Control Module
²Integrated Power Module (IPM)
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 0.5 mile and a speed of 15
mph, with the turn signal ON.

ADJUSTMENT
FOG LAMP ALIGNMENT
Prepare an alignment screen. (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING - EXTERIOR/HEAD-
LAMP UNIT - ADJUSTMENTS). A properly aligned
fog lamp will project a pattern on the alignment
screen 200 mm (8 in.) below the fog lamp center line
and straight ahead (Fig. 2). To improve visual inter-
pretation of the fog lamp pattern on the alignment
screen, the headlamps should be in the ªoffº position.
The fog lamps are adjusted by a adjustment screw
located on the underside of the fog lamp unit.

HEADLAMP LEVELING
SWITCH
DESCRIPTION
Some vehicles are equipped with a remote head-
lamp leveling system. This system allows the driver
to adjust the vertical headlamp aim from the interior
of the vehicle to compensate for passenger or cargo
load.
The headlamp leveling switch is located next to the
headlamp switch on the instrument panel (Fig. 6). Ifthe headlamp leveling switch is faulty or damaged,
the headlamp switch must be replaced.

ADJUSTMENT
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Verify that the headlamp leveling switch is in
the ª0º position.
(3) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.
(4) Verify proper tire inflation.
(5) Clean headlamp lenses.
(6) Verify that luggage area is loaded as the vehi-
cle is routinely used.
(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 10 meters (32.8 ft.) away from front
of headlamp lens (Fig. 8).
(2) If necessary, tape a line on the floor 10 meters
(32.8 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 ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp centerline 20 mm (0.75 in.). The high beam
pattern should be correct when the low beams are
aligned properly (Fig. 9). To adjust headlamp align-
ment, rotate adjustment screws to achieve the speci-
fied low beam cut-off location.
