WARNING
■ To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the ho od until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “READY” indi-
cator is off. When the hybrid system is operating, the gasoline engine may
automatically start, or the cooling fan may suddenly operate even if the
gasoline engine stops. Do not touch or approach rotating parts such as the
fan, which may lead to fingers or clothing (especially a tie, a scarf or a muf-
fler) getting caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap wh ile the
hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■ When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sa nd or dust
etc.).
● Do not use any coolant additives.

■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up the engine and turn off the hybrid system, wait
more than 5 minutes, and check the oil level on the dipstick.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat -
isfy the following grade and viscosity.
Oil grade: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE 0W-16 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-16 is not available, SAE
0W-20 oil may be used. However,
it must be replaced with SAE 0W-
16 at the next oil change.
Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for ea sier starting of
the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container label:
API registered marks is added
to some oil containers to help
you select the oil you should
use.
