PRE-AIMING INSTRUCTIONS

1. Inspect for badly rusted or faulty headlight assemblies.
2. These conditions must be corrected before a satisfactory

adjustment can be made.

3. Inspect tire inflation, and adjust if necessary.
4. If the fuel tank is not full, place a weight in luggage room of

vehicle to simulate weight of a full tank [3 kg (6.5 pounds)
per gallon.]

5. There should be no other load in the vehicle other than

driver or substituted weight of approximately 70 kg (150
pounds) placed in driver's position.

6. Thoroughly clean fog light lenses.
7. Place the vehicle on a level floor, perpendicular to a flat

screen 7.62 m (25.0 feet) away from the bulb center-marks
on the fog light lens.

8. Rock vehicle sideways to allow vehicle to assume its normal

position.

9. Bounce the front suspension through three (3) oscillations

by applying the body weight to hood or bumper.

11.Four lines of adhesive tape (or equivalent markings) are

required on screen or wall:

(1) Position a vertical tape or mark so that it is aligned with

the vehicle center line.

(2) Measure the distance from the center-marks on the fog

light lens to the floor. Transfer the measurement to the
screen. Horizontal tape or mark on the screen is for
reference of vertical adjustment.

(3) Measure the distance from the center line of the vehicle

to the center of each fog light. Transfer the measurement
to the screen. Vertical tape or mark on the screen with
reference to the center line of each fog light bulb.

FOG LIGHT ADJUSTMENT

1. The fog light will project on the screen upper edge of the

high intensity zone.

2. Turn the adjusting screws to achieve the specified upper

edge of the high intensity zone on the aiming screen.

Standard value:

(Vertical direction): Top of the hot zone should be

101 mm (4.0 inches) (0.76

°) downward from the

height of the fog light center.

Limit:

(Vertical direction): Top of the hot zone should be

15.24 cm (1.14

°) in maximum downward from the

height of the fog light center.

NOTE: The horizontal direction is non-adjustable. If the devia-
tion of the light beam axis exceeds the standard value, check
for improper/defective mounting location.

CAUTION

When making the aiming adjustment, be sure to block the
beam of those lights which are not being adjusted.
