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
● Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-in for-
mation display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, power control unit, radiato r, 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 r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ When working near the electric cooling fan or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fan may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 430)
■ 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.
ItemsParts and tools

4566-3. Do-it-yourself maintenance
Remove the dust from the air
intake vent with a vacuum
cleaner, etc.
Make sure to only use a vacuum to
suck out dust and clogs. Attempt-
ing to blow out dust and clogs
using an airgun, etc. may push it
into the air intake vent. (P. 4 6 0 )
If dust and clogs cannot be completely removed with the air int ake
vent cover installed, remove t he cover and clean the filter.
Turn the power switch off.
Using a Phillips screwdriver,
remove the clip.
Cleaning the hybrid batter y (traction bat-
ter y) air intake vent and filter
To prevent the fuel economy from being affected, visually
inspect the hybrid battery (traction battery) air intake vent p eri-
odically for dust and clogs. If i t is dusty or clogged or if “Mainte-
nance Required for Traction Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-information display, clean the
air intake vent using the following procedures:

Maintenance and care
■Scheduled maintenance of the air intake vent is necessary when
In some situations such as when the vehicle is used frequently or in heavy
traffic or dusty areas, the air intake vent may need to be cleaned more regu-
larly. For details, refer to “Schedule maintenance guide” or “O wner’s Manual
Supplement”.
■ Cleaning the air intake vent
●Dust in the air intake vent may interfere with the cooling of t he hybrid battery
(traction battery). If charging/discharging of the hybrid battery (traction bat-
tery) becomes limited, the distance that the vehicle can be driven using the
electric motor (traction motor) may be reduced and the fuel economy may
be reduced.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
■ If “Maintenance Required for Traction Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-information display
●If this warning message is displayed on the multi-information display,
remove the air intake vent cover and clean the filter. ( P. 456)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
It may take approximately 20 minutes after the hybrid system is started until
the warning message disappears. If the warning message does not disap-
pear, have the vehicle inspected by your Toyota dealer.
WARNING
■
When cleaning the air intake vent
● Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (traction battery) or other compo nents, a mal-
function or fire may occur.
● Before cleaning the air intake vent, make sure to turn the power switch off
to stop the hybrid system.
■
When removing the air intake vent cover
Do not touch the service plug located near the air intake vent. ( P. 82)

Vehicle specifications
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up the engine and turn 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. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat -
isfy the following grade and viscosity.
Oil grade: ILSAC GF-6B multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE 0W-16 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-16 is not available, SAE
0W-20 oil may be used. However,
it must be replaced with SAE 0W-
16 at the next oil change.
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 ea sier 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.
