Headlights
Adjustment
Eoforo adiu3ting th€ h.adlights:
. Park the vehicle on level surface.
. Make sure the tire prgssures are correct.
a The driver or someone who weighs the same should
sit in the driver's seat.
96 - 98 modols
1. Open the hood.
2. Check the horizontal adjustment indicator.
The "0" mark on the horizontal indicator gear
should be aligned with the mark on the horizontal
indicator.
HORIZONTAL INDICATOR
Check the vertical adjustment indicator. The bubble
should be centered underneath the longest scribe
mark on the gauge.
VERTICAL INDICATOR:
Headlight become very hot in use; do not touch them
or any attaching hardware immediately after they
have been turnsd off.
MARK
23-164
(Bubblol
lf either indicator is not aligned with its "0"mark as
described left column, an adjustment can be made
by using a Phillips screwdriver.
Adjust the headlights to local requirements by turn-
ing the adjusters.
After headlight replacement, it may bs necessary to
readjust the horizontal indicator gear.
. First install the headlioht, and adjust its horizon-
tal and vertical aimings according to local re-
quirements.
. Then check that the arrow on the horizontal indi-
cator gear is aligned with the mark on the hori-
zontal indicator.- lf they are not aligned, remove the screw,
adiust the indicator gear, and retighten the
screw.
NOTE: As the outer lenses are made ot an acryli-
coated, polycarbonated material, do not cover the
headlights when they are turned on.
