Aiming Adjustment Procedure

  1. Place the screen.
    NOTE:
    • Stop the vehicle at the perpendicular angle to the wall.
    • Set the screen so that it is perpendicular to a level load surface.
  2. Face the vehicle squarely toward the screen and make the distance between the headlamp center and the screen 10 m (32.8 ft).
  3. Start the engine and illuminate the headlamp (LO).
    NOTE:

    Block light from the headlamp that is not being adjusted with a thick fabric or another object, so that it does not reach the adjustment screen.

    CAUTION:

    Do not cover lens surface with tape, etc. because it is made from plastic.

  4. Use the aiming adjustment screw to adjust the elbow point projected by the low beams on the screen, so that it is within the aiming adjustment area.
