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, 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.
■ When working near the electric cooling fan or radiator grille
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. 369)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After turning off the hybrid
system, wait more than five mi nutes for the oil to drain back
into the bottom of the engine.

Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not avail-able, SAE 10W-30 oil may be
used. However, it should be
replaced with SAE 5W-30 at the
next oil change.
■ How to read oil container labels
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to
help you select th e oil you should use.

Lubrication system
*:5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W portion of the oil viscosity rating indicates the characteristic
of the oil which allows cold startab ility. Oils with a lower value before
the W allow for easier starting of the engine in cold weather.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as its oper-
ating temperature. An oil with a higher viscosity may be better suited
if the vehicle is operated at high speeds, or under extreme load con-
dition.
