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

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.
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 batt ery cooling parts See owner’s

6-3. Do-it-yourself maintenance
■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 the “Scheduled Maintenance Guide” or “Owner’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. Inspect and clean the air intake vent periodically.
● 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 shown on the multi-information display
●If this warning message is shown on the multi-information displ ay, remove
the air intake vent cover and clean the filter. ( P. 539)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer shown.
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. 90)

■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 minu tes, 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: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE 0W-16 is the best choice
for good fuel economy and
good starting 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 expl ained here as an example):
• The 0W in 0W-16 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 16 in 0W-16 indicates the vi scosity characteristic of the oil
when the oil is at high temperature. An oil with a higher visco sity
(one with a higher value) may be better suited if the vehicle i s
operated at high speeds, or un der extreme load conditions.
