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-16:
API grade SN “Resource-Conserving”, SN PLUS “Resource-Con-
serving” or SP “Resource-Conserving”; or ILSAC GF-6B multigrade
engine oil
0W-20 and 5W-30:
API grade SM “Energy-Conserving”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving” or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 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-16 oil is not avail-
able, SAE 0W-20 oil may be
used. However, it should be
replaced with SAE 0W-16 at the
next oil change.

sia)

Vehicle specifications
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 easier 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 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 SP”
means the oil quality designa-
tion by American Petroleum Ins-
titute (API).
Center portion: “SAE 0W-16”
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.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving”, SN PLUS “Resource-Conserving” or SP
“Resource-Conserving”; or ILSAC GF-6A 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 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, 5W-20
or 5W-30 engine oil is recom-
mended.
