Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Park the vehicle on level ground. After warming up the
engine and turning 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. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 oil is not avail-
able, SAE 5W-30 oil may be
used. However, it should be
replaced with SAE 0W-20 at the
next oil change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become difficult
to start, so SAE 0W-20 or 5W-
30 engine oil is recommended.

Vehicle specifications
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which
allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
• The 20 in 0W-20 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 labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designa-
tion by American Petroleum Ins-
titute (API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-
Conserving” means that the oil
has fuel-saving and environ-
mental protection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC)
Certification Mark is displayed on the front of the container.

Fuel information
■Use of ethanol blended gasoline in a gasoline engine
Toyota allows the use of ethanol blended gasoline where the ethanol content
is up to 10%. Make sure that the ethanol blended gasoline to be used has a
Research Octane Number that follows the above.
■If your engine knocks
●Consult any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
●You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
EU area:
You must only use unleaded gasoline conforming to European
standard EN228.
Select unleaded gasoline with a Research Octane Number of 95
or higher for optimum engine performance.
Except EU area:
You must only use unleaded gasoline.
Select unleaded gasoline with a Research Octane Number of 95
or higher for optimum engine performance.

NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and the emission control system to function improperly.
● EU area: Bioethanol fuel sold under names such as “E50” or “E85” and
fuel containing a large amount of ethanol should not be used. The use of
these fuels will damage the vehicle’s fuel system. In case of any doubt,
ask any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Except EU area: Bioethanol fuel sold under names such as “E50” or “E85”
and fuel containing a large amount of ethanol should not be used. Your
vehicle can use gasoline mixed with 10% max ethanol. The use of fuel
with more than 10% ethanol content (E10) will damage the vehicle’s fuel
system. You must ensure that refueling is carried out only from a source
where fuel specification and quality can be guaranteed. In case of any
doubt, ask any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
● Do not use the methanol blended gasoline such as M15, M85, M100.
The use of gasoline containing methanol may cause engine damage or
failure.
