Headlamp: Adjustments
ADJUSTMENT1. HEADLIGHT AIMING ADJUSTMENT
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 headlights.
- 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 (Headlight 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 headlights)
Draw vertical lines, for left and right, at the same position as the center mark for the low beam lights.
c. Check the headlight aim.
1. Align the paper and vehicle.
- Make the distance of 3 m (9.84 ft) between the headlights 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 degrees angle in accordance to the V line.
2. Start the engine.
3. Turn on the headlights and check that the aim is within the specified values shown in the illustration for low beam.
NOTE: The headlight lens is made of synthetic resin, so it is easily damaged.
4. Turn on the headlights and check that the aim is within the specified values shown in the illustration for high beam.
NOTE: The headlight lens is made of synthetic resin, so it is easily damaged.
d. Adjust the aim in the vertical direction:
Using a screwdriver, adjust the headlight aim within the specified range by turning aiming screw A.
NOTE:
- Adjust the headlight 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 headlight aim.
HINT: The optical axis aim moves downward when turning the screwdriver clockwise, and it moves upward when turning the screwdriver counterclockwise.
