Headlamp: Adjustments
HEADLAMP ASSEMBLYADJUSTMENT
1. ADJUST HEADLAMP AIMING
a. Place the vehicle in the following conditions:
- The area around the headlamp is not deformed.
- The vehicle is parked on a level surface.
- Tire inflation pressure is at the specified value.
- A driver is in the driver's seat and the vehicle is in a state ready for driving (fuel tank is full).
- The vehicle has been bounced several times.
b. Check the headlamp's aim (perform the following procedures while referring to the illustration).
1. Prepare a piece of thick white paper.
2. Stand the paper perpendicular to the ground at a location 3 m (9.8 ft) from the headlamps.
3. Ensure that the center line of the vehicle and the paper surface form a 90° angle as shown in the illustration.
4. Draw a horizontal line (H line) on the paper at the position where the high beam light from the headlamps will contact the paper.
5. Draw a vertical line (V line) on the paper at the position where the center of the vehicle is.
6. Draw 2 vertical lines (V RH and V LH lines) on the paper at the position where the light from the headlamps will contact the paper.
7. Mark the low beam center marks on the paper. Then draw a horizontal line (H RH and H LH lines)through the marks. This is where the low beam light from the headlamps will contact the paper.
HINT: The H RH and H LH line is 0.4° below the horizontal line (H line) of the headlamp axis.
8. Take appropriate measures to prevent influence of other lamps.
NOTE:
- Disconnect connectors of the other lamps so that the aim adjustment will not be affected. When connecting the connectors again, take care not to affect the aim adjustment.
- If covering the headlamps, finish it within 3 minutes. Note that the headlamp lens is made of synthetic resin and can be affected by heat.
9. Start the engine.
10. Turn the headlamps ON.
11. Check that light from the headlamps properly strike the positions shown in the illustration.
If not, adjust the lamps vertically.
HINT: Adjust each aim aspect of the RH and LH headlamps as shown.
c. Adjust the headlamps vertically.
1. Using adjusting bolt A and B, adjust the headlamp aim to the specified range.
HINT:
- First adjust the headlamps with adjusting bolt A. Since the headlamp moves horizontally during this adjustment, correct the horizontal position using adjusting bolt B.
- Rotate adjusting bolt A and B at a 5:1 ratio (5 turns of bolt A equals 1 turn of bolt B).
- Rotating a screwdriver clockwise makes the optical axis aim downward and rotating counterclockwise makes it upward.
