If beam-setting equipment is not available, proceed as follows :

1.	Inflate the tires to the specified pressure and remove any loads from the vehicle except the driver, spare tire, and tools.

2.	The vehicle should be placed on a flat floor.

3.	Draw vertical lines (passing through respective headlamp centers) and a horizontal line (passing through center of headlamps) on the screen.

4.	If headlamp leveling device is equipped, adjust the headlamp leveling device switch with 0 positions.

5.	With the headlamps and battery in normal condition, aim the headlamps so the brightest portion falls on the horizontal and vertical lines.

6.	Cover the headlamp outer projection (A) and set the cut-off position. [A Type] A : Vertical (High/Low beam) B : Horizontal (High/Low beam) [B Type] A : Vertical (High/Low beam) B : Horizontal (High/Low beam)
