in severe injury or death. It could
also damage your vehicle.
cExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
cDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-

Add fluid when the low washer fluid warning
light comes on. Add a washer solvent to the
water for better cleaning. In the winter sea-
son, add a windshield washer antifreeze.
Follow the manufacturer's instructions for
the mixture ratio.
CAUTION
Do not substitute engine antifreeze
coolant for windshield washer solution.
This may result in damage to the paint.cKeep the battery surface clean and dry.
Any corrosion should be washed off with
a solution of baking soda and water.
cMake certain the terminal connections
are clean and securely tightened.
cIf the vehicle is not to be used for 30 days
or longer, disconnect the negative (þ)
battery terminal cable to prevent dis-
charge.
WARNING
cDo not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15 min-
utes and seek medical attention.
cWhen working on or near a battery,
always wear suitable eye protection
and remove all jewelry.
cKeep the battery out of the reach of
children.
