CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
When working on the engine compartment
■
Make sure that the indicator on the "POWER" switch and the "READY" indicator
●
are both off.
Keep hands, clothing and tools away from the moving fans and engine drive belt.
●
Be careful not to touch the engine, power control unit, radiator, 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
●
compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
●
mable.
When working near the electric cooling fans or radiator grille
■
Be sure the "POWER" switch is off.
With the "POWER" switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning 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.
NOTICE
If you remove the air cleaner filter
■
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also, a backfire could cause a fire in the engine compartment.
