WARNING
 Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and
lighters. Never expose a battery
to an open flame or electric
sparks. Batteries give off a gas
which is highly flammable and
explosive. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery. Do not let battery fluid contact
eyes, skin, fabrics, or paint
because battery fluid is a corro-
sive acid. If battery fluid gets on
your skin or in your eyes, immedi-
ately flush the area with water
thoroughly. Seek medical help
immediately if acid has entered
the eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention
immediately.

Maintenance and Service11
– CONTINUED –
It is unnecessary to periodically check the
battery fluid level or periodically refill with
distilled water.
11-26. FusesNOTEFuse rating and using circuit are
described on the fuse box cover.
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.
 To lessen the risk of sparks,
remove rings, metal watchbands,
and other metal jewelry. Never
allow metal tools to contact the
positive battery terminal and
anything connected to it WHILE
you are at the same time in
contact with any other metallic
portion of the vehicle because a
short circuit will result. Keep everyone including children
away from the battery. Charge the battery in a well-venti-
lated area.Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Batteries also contain
other chemicals known to the
State of California to cause
cancer. Wash hands after
handling.
CAUTION
Never use more than 10 amperes
when charging the battery because
it will shorten battery life.
CAUTION
Never 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.
