Seat one person in the driver's seat.
Position the vehicle straight ahead and perpendicular to the white screen.
Set the headlights 3 m {9.8 ft} from the white screen.
Place an object in front of the headlight not being adjusted to block its light beam.

NOTE:
- If the adjusting bolts are tightened first, then loosened, they will continue to loosen when the vehicle is in motion and may cause the headlights to become misaligned. Always turn the screws in the tightening direction.
Turn the adjusting bolts to adjust the headlight so that the elbow point is in the shaded area shown in the figure.
