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.
n When working on the engine compartment:
Keep hands, clothing, and tools away from the moving fan and engine
l
drive belt.
Be careful not to touch the engine, inverter, radiator, exhaust manifold, etc.
l
right after driving as they may be hot. Oil and other fluids may also be hot.
l Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
l Do not smoke, cause sparks or expose an open flame to fuel or the 12 volt
battery. Fuel and 12 volt battery fumes are flammable.
Be extremely cautious when working on the 12 volt battery. It contains poi-
l
sonous and corrosive sulfuric acid.
Never touch, disassemble, remove or replace the high voltage parts,
l
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
When the hybrid system is operating with the "READY" light on, the engine
l
may suddenly start in some cases. When you inspect the engine compart-
ment, be sure to turn off the hybrid system.
When working near the electric cooling fan or radiator grille
n
Be sure the "POWER" switch is OFF.
With the "POWER" switch in ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (→P. 373)
