CALIBRATING THE SCREEN

To check the aimer for accuracy, place a car in front of a screen or a flat vertical wall, at a
distance of 25 feet (7.6m).

Trace ormarkwithtapethelinesasshowninthefigurebelow.

If the headlamp mounting height of the vehicle used for the test is more than 36in, then a
Nominal Vertical Aim line at the distance specified in the Table 1 shall be traced.

Perform the preparation for headlamp aim as detailed.

Proceed to aim the lower beam as explained in next page.
