ADJUSTMENT USING AN ADJUSTMENT SCREEN (LIGHT/DARK BORDERLINE)
ADJUSTING
1. Set the distance between the screen and the center of the driving lamp lens as shown in the figure.
2. Turn head lamp switch high and driving lamp switch ON so that front driving lamps turn ON.
3. Adjust driving lamps using adjusting screws make sure of the following.

When performing this adjustment, cover the headlamps and the opposite driving lamp, if necessary.

Vertical deflection of maximum illuminance point to be adjusted to stand at 21.8cm (8.58in) below driv-
ing lamp height (h).

Horizontal deflection of maximum illuminance point to be adjusted to stand within 0 ± 12.5cm (0±8.58in)
against line (V) on screen where a line passing through driving lamp center, parallel to vehicle center
line, cross screen.
