HEADLIGHT AIMING ADJUSTMENT WITH SCREEN
1) Make sure the following items.
Place vehicle on a flat surface in front of blank wall (screen)
(1) ahead of headlight surface.
Distance between screen and headlight
“a” : 10 m (32.8 ft.)
Adjust air pressure of all tires to a specified value respec-
tively.
Bounce vehicle body up and down by hand to stabilize sus-
pension.
Carry out with one driver aboard.
Driver’s weight
: 75 kg (165 lb)
2) Check to see if hot spot (high intensity zone) of each main
(low) beam axis falls as shown in figure.
Hot spot specification
“H” : Approx. 130 mm (5.15 in.)
3) Align headlight aiming to specification by adjusting aiming
screw and aiming gear if it is not set properly.

NOTE:
Unless otherwise obligated by local regulations, adjust
headlight aiming according to following procedure.
After replacing headlight, be sure to adjust aiming.
