Maintenance and care
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
●Hybrid vehicles: Make sure that the “POWER ON” on the multi-information dis-
play and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Gasoline vehicles: 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.
●Hybrid vehicles: 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.
●Gasoline vehicles: 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.
●Hybrid vehicles: Do not smoke, cause sparks or expose an open flame to fuel.
Fuel fumes are flammable.
