When using an aiming board, position the
vehicle five meters from and square to the aiming
board. Gently rock the vehi cle and allow the suspen-
sion to stabilize. Mark a reference line on the board to
correspond with the horizontal centre line of the
headlamp low beam bulbs. Mark two reference lines on the board to
correspond with the vertical centre lines of
the
headlamp low beam bulbs. Switch on the headlamps and select low
beam. Adjust the headlamps by turning the adjust-
ing screws located at the rear of the headlamp
assemblies. Adjust the headlamps to comply with local
regulations. As a guide, adjust the lamps so that the
low beam pattern strikes the aiming board with the
horizontal cut off point 50 mm below the headlamp
bulb horizontal centre line and the point where the
beam raises from the horizontal is on the headlamp
low beam bulb vertical centre line.
