Maintenance and service/Fuses
remove rings, metal watchbands,
and other metal jewelry. Never
allow metal tools to contact the
positive battery terminal and any-
thing connected to it WHILE you
are at the same time in contact
with any other metallic portion of
the vehicle because a short cir-
cuit will result.
. Keep everyone including children
away from the battery.
. Charge the battery in a well-
ventilated area.
. Battery posts, terminals and re-
lated accessories contain lead
and lead compounds, chemicals
known to the State of California
to cause cancer and reproductive

Wash hands after handling . 1) Cap
2) Upper level
3) Lower level
It is unnecessary to periodically check the
battery fluid level or periodically refill with
distilled water.
However, if the battery fluid level is below
the lower level, remove the cap. Fill to the
upper level with distilled water.
CAUTION
Never use more than 10 amperes
when charging the battery because
it will shorten battery life. Fuses CAUTIONNever replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the fuse box cover on the driver ’ s
seat side. To remove the cover, pull it out.11-42
