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.
