Interior features
■Windshield fog detection function
When automatic mode is set, the humidity sensor ( →P. 525) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated air mode will also cool the vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditio ning system in Eco drive mode
● In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Turn off Eco drive mode
● Even when the drive mode is set to Eco drive mode, the air conditioning eco
mode can be turned off by pressing .
■ When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is pressed.
■ Ventilation and air conditioning odors
●To let the fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring:
The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.

Maintenance and care
Hybrid battery (traction battery) air intake vent
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. 641)
If dust and clogs cannot be comple tely removed with the air intake
vent cover installed, remove the cover and clean the filter.
Turn the power switch off.
Using a Phillips screwdriver,
remove the clip.
To prevent an increase in fuel consumption, visually inspect the
hybrid battery (traction battery) air intake vent periodically for
dust and clogs. If it is dusty or clogged or if “Maintenance
required for Traction battery cooling parts See owner’s manual”
is shown on the multi-information display, clean the air intake
vent using the following procedures:

7-3. 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 “Own\
er’s
Manual Supplement”.
■ Cleaning the air intake vent
●Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If the hybrid battery (traction battery) overheats, the dis-
tance that the vehicle can be driven using the electric motor (traction motor)
may be reduced and the fuel consumption may increase. 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 display, remove
the air intake vent cover and clean the filter. ( →P. 637)
● 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 components, a mal-
function or fire may occur.
■ When removing the air intake vent cover
Do not touch the service plug located near the air intake vent. ( →P. 85)

■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changingthe engine oil. Park the vehicle on level ground. After warming up the
engine and turning 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 us ed 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 with 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.
