SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp are on low beam setting.
(2) Verify that the headlamp leveling switch is in
the “0” 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.

HEADLAMP/FOG LAMP ADJUSTMENT USING
ALIGNMENT SCREEN
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. 1).
(2) Place 75 kg in the driver’s seat to simulate the
ride height of the vehicle when driven.
(3) If necessary, tape a line on the floor 10 meters
(32.8 ft) away from and parallel to the wall.
(4) From the floor up 1.27 meters (5 ft), tape a line
on the wall at the centerline of the vehicle. Sight
along the centerline of the vehicle (from rear of vehi-
cle forward) to verify accuracy of the line placement.
(5) Rock vehicle side-to-side three times and allow
suspension to stabilize.
(6) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(7) 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.
(8) Place a tape line 130 mm below and parallel to
the center of headlamp line.
(9) Measure distance from the centerline of the
vehicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle centerline. Use these lines for left/
right adjustment reference.
HEADLAMP ADJUSTMENT
A properly aimed low beam headlamp will project a
high intensity light pattern on the screen with the
horizontal cut-off line aligned with the tape line 130
mm (5.12 in.) below the headlamp centerline (Fig. 1).
The intersection of the horizontal and 15 degree cut-
off lines in the projected pattern should align to the
intersection of the headlamp centerline vertical tape
line and the tape line 130 mm (5.12 in.) below the
headlamp horizontal centerline. The high beams on a
vehicle with aero headlamps cannot be aligned. The
high beam pattern should be correct when the low
beams are aligned properly.
To adjust headlamp alignment, rotate alignment
screws (Fig. 2) to achieve the specified low beam hot
spot pattern.
