iQ_WE_74014EEngine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota rec-
ommends the use of approved “Toyota Genuine Motor Oil”. Another
motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving” or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in
cold weather.
If SAE 0W-20 oil is not available,
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 5W-30 or lower vis-
cosity engine oil is recom-
mended.
Temperature range anticipated before
next oil change.

Vehicle specifications
iQ_WE_74014E
The 0W portion of the oil viscosity rating 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 oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity 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 containers
to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion: “Resource-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certification
Mark is displayed on the front of
the container.

Fuel infor mation
Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
If your engine knocks
Consult any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
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 emission control system to function improperly.
EU area:
Your vehicle must use only unleaded gasoline conforming to Euro-
pean standard EN228. For optimum engine performance, select
unleaded gasoline with a Research Octane Number of 95 or higher.
Except EU area:
Your vehicle must use only unleaded gasoline. For optimum engine
performance, select unleaded gasoline with a Research Octane
Number of 95 or higher.
