the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is selected.
■ Setting confirmation screen
■ Operation of automatic airflow control
●In order to maintain a comfortable interior, airflow may be directed to seats
without passengers immediately after the hybrid system is start ed and at
other times depending on the outside temperature.
● After the hybrid system is started, if passengers move around i nside or
enter/exit the vehicle, the system cannot accurately detect the presence of
passengers and automatic airflow control will not operate.
■ Operation of manual airflow control
Even if the function is manually switched to directing airflow to only the front
seats, when a rear seat is occupied, it may automatically direc t airflow to all
seats.
■ To return to automatic airflow control
With the indicator off, turn the power switch off.
After 60 minutes or more elapse, turn the power switch to ON.

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.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch dependin g 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, helpin g to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditionin g eco
mode
● In the air conditioning eco mode, the air conditioning system i s controlled as
follows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict h eating/
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 the air conditioning eco mode
● When the driving mode is set to Eco driving mode, the air condi tioning eco
mode will be turned on automatically. Even in this case, the ai r conditioning
eco mode can be turned off by selecting . ( P. 347)
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is
selected.

When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■ 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 m ay enter into
and accumulate in the air conditioning system. This may then ca use 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 t he blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.
■ Air conditioning filter

■Customization
Settings (e.g. A/C auto switching operation) can be changed. (C ustomizable
features: P. 690)
WARNING
■ To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weathe r. T h e
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking
your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
NOTICE
■ To prevent 12-volt b attery discharge
Do not leave the air conditioning system on longer than necessa ry when the
hybrid system is off.
■ When repairing/replacing parts of the air conditioning system
Have repair/replacement performed by your Toyota dealer. When a part of
the air conditioning system, such as the evaporator, is to be r eplaced, it
must be replaced with a new one.
■ Air outlets
The air outlets become hot when used for heating. Therefore, us e caution
and adjust the air outlets accordingly.
● 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.
