HEADLIGHT BEAM SETTING (STANDARD PROCEDURE)
Before setting the headlight beams, adjust air pressures of four tires to a specified value respectively. Move
the vehicle up and down by hand to settle its attitude. Then move it over a flat surface. There are available
a variety of headlight beams setting methods (e.g., the screen method using a focusing tester, etc.). How-
ever, the method described here does not use such tester.
Beam alignment
Unless otherwise obligated by the local regulations, align the headlight beams according to the following
procedure. Place a blank wall 7.6 m (25 ft) ahead of the headlight. Check to see if the hot spot (high
intensity zone) of each main (low) beam axis falls as illustrated below. The beam alignment should be
carried out with one driver (68 kg, 150 lb) aboard.
