  1. INSPECT Check adjustment of low beam headlamps.

    IMPORTANT For the height adjustment the light-dark boundary of the light beam must be coincident with the horizontal separating line (1) in the headlamp aimer (01). When carrying out the lateral setting, the bent line (2) of the light bundle must lie below the central mark (3) and start on the horizontal broken line (1).

  2. Vehicles with xenon headlamps: If the headlamps are misaligned, connect STAR DIAGNOSIS subject to separate repair order and conduct zero position adjustment of axle and level sensors.
  3. Correct adjustment of low beam headlamps if necessary by turning the adjustment screws (H, S).
