Headlamp: Adjustments
1. ADJUST HEADLIGHT AIMINGHeadlight And Taillight System:
a. Inspect the headlights aiming.
Do the following items before inspection.
- Make sure the body around the headlight is not deformed.
- Park the vehicle on a level spot.
- The driver gets into the driver's seat and puts the vehicle in a state ready for driving (with a full tank).
- Bounce the vehicle several times.
b. Adjust the headlight aiming.
- Vertical Alignment:
If the bubble is out of the acceptable range of the beam angle gauge, adjust it using bolt A.
- Horizontal Alignment:
If the edge of the lens does not match "0" mark, adjust the lens using bolt B.
HINT: After adjusting the headlight in vertical direction, check that the light has been shifted from the adjusted position in the horizontal direction.
2. REPLACE HEADLIGHT
a. Replace the headlight.
b. Place the vehicle in the following conditions.
- The area around the headlight is not deformed.
- The vehicle is parked on a level surface.
- Tire inflation pressure is the specified value.
- A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).
- The vehicle has been bounced several times.
c. Check the headlight aiming.
1. Prepare a thick white paper.
2. Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
3. Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown in the illustration.
4. Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
5. Draw a vertical line (V line) to where the center line of the vehicle is to be.
6. Draw 2 vertical lines to where the both headlights should strike (V RH and V LH lines).
7. Draw a horizontal line (by connecting the both low beam center marks) to where the headlights should strike (H RH and H LH lines)
HINT: The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
8. Start the engine.
9. Turn the headlights ON.
10. Check that the headlights properly strike the position shown in the illustration.
11. If not, adjust the lights in the vertical or horizontal direction.
HINT: As shown in the illustration, adjust each aim of the RH and LH lights.
d. Vertical Alignment:
Adjust the headlight aiming.
1. Using adjustment bolt A, adjust the headlight aiming to within the specification.
2. Make sure the gauge bubble is within the acceptable range.
HINT: If the gauge bubble is outside the acceptable range, check that the vehicle is parked on a level spot.
Readjust the headlight aiming after parking the vehicle on a level spot.
e. Horizontal Alignment:
Adjust the headlight aiming.
If the edge of the lens does not match the paper as shown in the illustration, adjust the lens using bolt B.(See step 5)
HINT: After adjusting the headlight in vertical direction, check that the light has been shifted from the adjusted position in the horizontal direction.
