CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■
When working on the engine compartment:
●
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
●
Be careful not to touch the engine, 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 or the bat-
tery. Fuel and battery fumes are flammable.
●
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
