WARNING
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 and 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.
■ When working near the electric cooling fans or radiator grille
Be sure the engine switch is in the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system). With the engine
switch in the “ON” position (vehicles without a smart key system) or IGNI-
TION ON mode (vehicles with a smart key system), the electric cooling fans
may automatically start to run if the air conditioning is on and/or the coolant
temperature is high. ( P. 483)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oilPark the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

Vehicle specifications
■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: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
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 wi th 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 label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark
is added to some oil containers
to help you select the oil you
should use.
