Maintenance and care
iQ_WE_74014E
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, 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 bat-
tery. Fuel and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
When working near the electric cooling fan or radiator grille
Vehicles without smart entry & start system:
Be sure the engine switch is in the LOCK position.
With the engine switch in the ON position, the electric cooling fan may
automatically start to run if the air conditioning system is on and/or the
coolant temperature is high. (P. 342)
Vehicles with smart entry & start system:
Be sure the “ENGINE START STOP” switch is in the OFF.
With the “ENGINE START STOP” switch in the IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning
system is on and/or the coolant temperature is high. (P. 342)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

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 engine,
wait more than 5 minutes for the oil to drain back into the bot-
tom of the engine.
Hold a rag under the end and pull the dipstick out.

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.
