or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
Items
Parts and tools
■
When working on the engine
compartment
●
Make sure that “IGNITION ON”
on the multi-information display
and the “READY” indicator are
both off.
●
Keep hands, clothing and tools
away from the moving fan.
●
Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
●
Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●
Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●
Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■
When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. (

Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc., from getting in your
eyes.
