Interior features
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
●If you turn off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 515) 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 conditioning system when the blower customization
is set to “ECO”
●In the “ECO” mode, the air conditioning system is controlled as follows to
prioritize 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
• Set the blower customization to “FAST” or “NORMAL” mode.
●When the driving mode is set to Eco driving mode, the fan speed setting
mode will be changed to “ECO” mode automatically. Even in this case, the
fan speed control mode can be changed by pressing . (P. 412)
■When the outside temperature falls to nearly 0C (32F)
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.
■ Air conditioning filter
P. 609
■ Customization
Settings (e.g. A/C auto switching operation) can be changed.
(Customizable features: P. 708)
WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

NOTICE
■Humidity sensor
● Do not spray the glass cleaner on the sensor or subject it to strong impacts
● Do not stick anything on the sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
hybrid system is off.
■ Air outlets
The air outlets become hot when used for heating. Therefore, use caution
and adjust the air outlets accordingly.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. ( P. 513)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor

6-4. Using the other interior features
Please use as a power supply for electronic goods that use less than
12 V DC/10 A (power consumption of 120 W).
The power outlets can be used when the power switch is in ACCESSORY or
ON mode.
Power outlets
FrontRear (vehicles without solar
charging system)
Open the lid. Open the lid.
Rear (vehicles with solar
charging system)
Open the lid.
NOTICE
● To avoid damaging the power outlets, close the lid when the power outlet
is not in use.
Foreign objects or liquids that enter the power outlets may cause a short
circuit.
● To prevent 12-volt battery discharge, do not use the power outlet longer
than necessary when the hybrid system is off.

When trouble arises
Connect the power plug to the power outlet socket. (P. 536)
Connect the bottle to the com-
pressor.
As shown in the illustration, insert
the bottle securely into the com-
pressor until the upper side of the
mark on the bottle is aligned with
the upper end of the notch.

When trouble arises
Inflate the tire until the specified air pressure is reached.
The sealant will be injected
and the pressure will spike to
between 300 kPa (3.0 kgf/cm2
or bar, 44 psi) and 400 kPa
(4.0 kgf/cm2 or bar, 58 psi),
then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 to 5
minutes after the switch is
turned on.
• Turn the compressor switch
off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• The tire can be inflated for about 5 to 20 minutes (depending on
the outside temperature). If the tire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
• If the tire inflation pressure exceeds the specified air pressure, let
out some air to adjust the tire inflation pressure. ( P. 670, 704)
With the compressor switch off, disconnect the hose from the valve
on the tire and then pull out the power plug from the power outlet
socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.
