CAUTION
The engine compartment contains many mechanisms and fluids that many move
suddenly, become hot, or become electrically energized. To avoid death or serious
injury:
■When working in 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 and power steering
fluid reservoir, 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 or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. 
Fuel and battery fumes are flammable.

It contains poisonous and corrosive sulfuric acid.
■When the engine is running
Perform maintenance checks with adequate ventilation
■When working near the electric cooling fan or radiator grill:
Be sure the ignition is off. With the igni tion on, th
e electric cooling fan may automat-
ically start to run if the air conditioning is on and/
or if the coolant temperature is
high. ( P.262 )
■When working on or under the vehicle:
