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.
■
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, inverter, 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 or rags, in the
engine compartment.
● 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-
sonous and corrosive sulfuric acid.
● Never touch, disassemble, remove or replace the high voltage parts,
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
may suddenly start in some cases. When you inspect the engine compart-
ment, be sure to turn off the hybrid system.

ically start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 373)
