Pre-Aiming Instructions
FOG LIGHT AIMINGPRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty 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 fuel tank is not full, place a weight in the trunk of the vehicle to simulate weight of a full tank [3 kilograms (6.5 pounds) per gallon.]
5. There should be no other load in the vehicle other than driver or substituted weight of approximately 70 kilograms (150 pounds) placed in Driver position.
6. Thoroughly clean the fog light lenses.
7. Place the vehicle on a level floor, perpendicular to a flat screen 7.62 meters (25.0 feet) away from the bulb center-marks on the headlight 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 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 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 is for reference to the center line of each fog light.
FOG LIGHT ADJUSTMENT
1. Check if the beam shining onto the screen is at the standard value.
2. If it is not within the standard value range, adjust by turning the adjusting screw.
Standard value:
(Vertical direction): Top of the hot zone should be 101 mm (4.0 inches) (0.760) downward from the height of the fog light center.
Limit:
(Vertical direction): Top of the hot zone should be 152mm (6.0 inches) (1.140) in maximum downward from the height of the fog light center.
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.
INTENSITY MEASUREMENT
1. Set the headlights to high-beam
2. Using a photometer, and following its manufacturer's instruction manual, measure the headlight center intensity and check to be sure that the limit value is satisfied.
Limit:
40,000 cd or more {When a screen is set 18.3m (60.0 feet) ahead of the vehicle}
NOTE: When measuring the intensity maintain an engine speed of 2,000 r/min, with the battery fully charged.
There may be special local regulations pertaining to headlight intensity Be sure to make any adjustments necessary to satisfy such regulations.
If an illuminometer is used to make the measurements, convert its values to photometer values by using the following formula.
I =Er2 Where:
- I = intensity (cd)
- E = illumination (lux)
- r = distance (m) from headlights to illuminometer
CAUTION: 1. On the headlight not yet adjusted, perform aiming with connector removed and the lights switched off, if applicable. in addition, care should be taken to prevent a change of optical axis when connector is reconnected.
2. Plastic outer lens are equipped with headlights. If the lens surface is covered, headlight operation time should be within 3 minutes. In addition, do not mask the headlight with tape, etc.
