Headlamp: Adjustments
ADJUSTMENT1. HEADLIGHT AIM ONLY
HINT:
- Perform aim adjustment with low-beam.
- Since the low-beam light and the high-beam light move as a unit, aiming the low-beam light will correct the high-beam light.
a. Prepare vehicle in the following conditions.
- Check that any damage or deformation does not exist on the body around the headlamps.
- Fuel tank is full.
- The tire inflation pressure is at the specified level.
- Vehicle is parked on a level surface.
- A person having an average weight (68 kg (149.91 lb)) sits in the driver's seat.
- Vehicle is bounced up and down to stabilize the suspension to the normal position.
b. Prepare a thick white paper (draw base lines).
HINT:
- Stand the paper against a wall.
- The base lines differ for "Low-beam inspection" and "High-beam inspection".
1. V line (Vehicle center position)
Draw a vertical line down the center of the paper in order to align it with the center of the vehicle.
2. H line (Headlamp height)
Draw a horizontal line across the paper at the same height from the ground as the center mark for the low-beam lights.
3. V LH line, V RH line (Center mark position of right and left headlamps)
Draw vertical lines, for left and right, at the same position as the center mark for the low-beam lights.
c. Check the headlamp aim.
1. Align the paper and vehicle.
- Make the distance of 3 m (9.84 ft) between the headlamps and the paper. Place the paper against a wall with the H line being at the same height as the center mark.
- Align the center of the vehicle with the V line on the paper, and ensure that the paper is at a 90 ° angle in accordance to the V line.
2. Start the engine.
3. Turn on the headlamps and check that the aim is within the specified values shown in the illustration.
NOTE: The headlamp lens is made of synthetic resin, so it is easily damaged.
d. Adjust the aim in the vertical direction:
Using a screwdriver, adjust the headlamp aim within the specified range by turning aiming screw A.
NOTE:
- Adjust the headlamp aim by turning the screw in the tightening direction.
- When the screw is tightened excessively, loosen it once and re-tighten it to adjust the headlamp aim.
HINT: The optical axis aim moves downward when turning the screwdriver clockwise, and it moves upward when turning the screwdriver counter clockwise.
