23CHECKING ELECTRIC COOLING
FANS
!
!
G220A01A-AAT
WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the cooling fan, so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases the fan will automatically shut off.
This is a normal condition.
G210B03A-AAT
Checking the Battery
Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals
should be removed using a solution of house-
hold baking soda and warm water. After the
battery terminals are dry, cover them with a light
coating of grease. o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle's generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in
the area.
o Keep children away from the area.
PROPOSITION 65 WARNING:Battery posts, terminals, and related acces-
sories 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.
