ON-VEHICLE SERVICE

FRONT FOG LIGHT AIMING

M1540400300282

PRE-AIMING INSTRUCTIONS

1. Inspect for rusted or faulty front fog light 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 the trunk of the

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 68 kg (150
pounds) placed in driver's position.

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

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

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

normal position.

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

by applying the body weight to the hood or bumper.

10.Measure the center of the front fog lights as shown in the

illustration.

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 of the front 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 front fog light. Transfer the
measurement to the screen. Vertical tape or mark on the
screen is for reference to the center line of each front fog
light.

FOG LIGHT ADJUSTMENT

1. Check if the beam shining onto the screen is at the standard

value.

Standard value:

(Cutoff line direction): The horizontal line 153.0 mm

(6.02 inches) (1.15 degrees angle) below the hori-
zontal line (H)

Limit:

(Vertical direction): Area from 53.2 mm (2.09 inches)

(0.4 degrees angle) above the cutoff line to 99.8
mm (3.93 inches) (0.75 degrees angle) below the
cutoff line

(Horizontal direction): Vertical line (V)

± 599.7 mm (±

23.6 inches) (

± 4.5 degrees angle)

2. If it is not within the standard value range, adjust by turning

the adjusting screw.

NOTE: The horizontal direction is non-adjustable. If deviation of
the light beam axis exceeds the standard value, check that the
mounting location or some other points are not faulty.
