Notice: Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim first will result in an incorrect headlamp aim.

dot on each lamp;
if left low beam, subtract two
inches. Record this distance.
3. At the wall or other flat surface, measure from the
ground upward the recorded distance from Step

and draw or tape a horizontal line the width of
the vehicle.
