Headlight
Description
The low beam lights are proiector-type lights which are more compact while maintaining sufficient brightness. Bundling
the light rays reduces stray light and yields a spotlight-effect which improves visibility during night or foul weather driving.
For easier aiming, the headlights are equipped with vertical and horizontal gauges.
NOTE: As the oute. lenses are made oI a resin material, don't cover the headlights when they a.e turned on.

a Push down on the tront and rear bumDers several
times to make sure the car is sitting normally.
a When installing a new headlight assembly, tighten the
four mounting bolts so that.the indicator in the verti-
cal gauge comes to the "O" mark.
1. Open the hood.
2. Check that both the horizontal and vertical gauge
read " O" .
. lf the gauges rcad "O", check headlight aiming
with the aiming charts on page 23-163. (lf aim-
ing isn't correct, refer to the trame repair chart
in section 20.)
a lf one o. both gauges don't read "O". go to step
23-162
3. Turn the low beams on. lJ necessary, align the ver-
tical indicator with its "O" mark by turning the ver-
tical adiuster with a Phillips screwdriver, and check
aiming with the chart on page 23-163.
lf necessary, align the horizontal indicator with its"0" mark by turning the horizontal adjuster with a
Phillips screwdriver, and check aiming with the chart
on page 23-163.
4.
5.Recheck that the vertical indicator bubble is aligned
with "o" 1 1.
lf necsssary, adjust as described in step 3.
Turn the high beams on and check aiming with the
charts on page 23-163.
