HEADLAMP LEVELING
SWITCH - EXPORT
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. 16).
If the headlamp leveling switch is faulty or damaged,
the headlamp switch must be replaced.
DIAGNOSIS AND TESTING - HEADLAMP
LEVELING SWITCH - EXPORT
The headlamp leveling switch is located next to the
headlamp switch on the instrument panel. (Refer to 8
- ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
HEADLAMP SWITCH - DIAGNOSIS AND TEST-
ING) for diagnosis of the headlamp leveling switch. If
the headlamp leveling switch is faulty, the headlamp
switch must be replaced.

HEADLAMP UNIT
STANDARD PROCEDURE
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. 19).
(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 (Fig. 20). To adjust headlamp verti-
cal alignment, rotate adjustment screw to achieve the
specified low beam cut-off location.
STANDARD PROCEDURE - HEADLAMP UNIT
ALIGNMENT - EXPORT
HEADLAMP UNIT ALIGNMENT PREPARATION
(1) Verify that the headlamp leveling switch is in
the “0” position.
(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.
