WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away from
the battery.
Hydrogen, which is a highly com-
bustible gas, is always present in
battery cells and may explode if
ignited.
Keep batteries out of the reach of
children because batteries con-
tain highly corrosive SULFURIC
ACID. Do not allow battery acid
to contact your skin, eyes, cloth-
ing or paint finish.
If any electrolyte gets into your
eyes, flush your eyes with clean
water for at least 15 minutes and
get immediate medical attention.
If possible, continue to apply
water with a sponge or cloth until
medical attention is received.If electrolyte gets on your skin,
thoroughly wash the contacted
area.
If you feel a pain or a burning
sensation, get medical attention
immediately.
Wear eye protection when charg-
ing or working near a battery.
Always provide ventilation when
working in an enclosed space.
o When lifting a plastic-cased battery, ex-
cessive pressure on the case may cause
battery acid to leak, resulting in personal
injury. Lift with a battery carrier or with
your hands on opposite corners.
o Never attempt to charge the battery when
the battery cables are connected.
o The electrical ignition system works with
high voltage.
Never touch these components with the
engine running or the ignition switched
on.
WARNING:
CHECKING 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.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on auto-
matically if the engine coolant temperature is
high or whenever the air conditioning is in
operation.
