Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
CAUTION
D
When the hybrid system is on, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
D
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
D
If the hybrid system is hot, do not
remove the radiator cap or loosen
the drain plugs to prevent burning
yourself.
D
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
D
Do not smoke, cause sparks or al-
low open flames around fuel or the
batteries. Their fumes are flam-
mable.
D
When the hybrid system is operat-
ing with the “READY” light on, the
engine is automatically started in
some case. When you inspect the
engine compartment, be sure to
press the “POWER” switch to the
“OFF” mode.
D
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
D
Be sure that the hybrid system is
in the “OFF” mode if you work near
the electric cooling fans or radiator
grille. With the ignition on, the
electric cooling fans will automati-
cally start to run if the engine cool-
ant temperature is high and/or the
air conditioning is on.
D
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.

ing on the batteries. It contains poi-
sonous and corrosive sulfuric acid
