ADJUSTMENTS
HEADLAMP ALIGNMENT PREPARATION
LH vehicle headlamps are equipped with a bubble
level to aid up/down headlamp alignment. The bubble
level is used to assist headlamp alignment when
compensating for vehicle ride height changes due to
heavy luggage compartment loads or vehicle ride
height changes. The vehicle should always be on a
level surface when headlamp alignments are checked
or changed. Headlamp alignment should always be
first attempted by using the bubble level.
The bubble levels cannot be calibrated. The bubble
level adjustments are set by the manufacturer. Hori-
zontal alignment does not ordinarily have to be
changed except in the case of body damage or tam-
pering.
(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 not heavily loaded.
(6) 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.
HEADLAMP AND FOG LAMP ADJUSTMENT
USING ALIGNMENT SCREEN
NOTE: LH vehicle headlamps should be aligned
using the low beams. The high beams should be
used to verify low beam settings.
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.
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall.
(3) From the floor up 1.27 meters (5 ft.), tape a
line on the wall at the center line of the vehicle.
Sight along the center line of the vehicle (from rear
of vehicle forward) to verify accuracy of the line
placement.
(4) Rock vehicle side-to-side three times to allow
suspension to stabilize.
(5) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(6) Measure the distance from the center of the
headlamp bulbs to the floor, or refer to Headlamp
Alignment Measurement Chart. Transfer measure-
ment to the alignment screen (with tape). Use this
line for up/down adjustment reference. Individual
vehicles may vary.
(7) Measure distance from the center line of the
vehicle to the center of the headlamp bulbs, or refer
to Headlamp Alignment Measurement Chart. Trans-
fer measurements to screen (with tape) to each side
of vehicle center line. Use these lines for left/right
adjustment reference (Fig. 1).
NOTE: There are reference marks on the lens to
assist in locating the lamp centers.
