Interior features
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
vehicle 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 r ecirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.308)
■When the outside temperature
is low
The dehumidification function may
not operate even when the “A/C”
switch is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning 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.
●To reduce potential odors from
occurring:
• It is recommended that the air conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may
be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

WARNING
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing
Do not touch the rear view mirror
surfaces when the outside rear
view mirror defoggers are on.
■When the windshield wiper
de-icer is operating
Do not touch the glass at lower
part of the windshield or to the
side of the fron t pillars when the
windshield wiper de-icer is on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the hybrid system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.

■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
In order to reduce the air condition-
ing power consumption, the air con-
ditioning system may switch to
recirculated air mode automatically.
This may also reduce fuel consump-
tion.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” on will dehu-
midify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows
may fog up more easily.
■Eco air conditioning mode
When Eco drive mode is selected
using the driving mode select
switch, eco air conditioning mode
turns on.
When a drive mode other than Eco
drive mode is sele cted, eco air con-
ditioning mode may turn off.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restri cted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.308)
• Turn off Eco air conditioning 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 air conditioning eco mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
is low
The dehumidification function may
not operate even when “A/C” is
pressed.

3345-1. Using the air conditioning system and defogger
1Press the automatic mode
switch.
The dehumidification function
begins to operate. Air outlets and
fan speed are automatically
adjusted according to the tempera-
ture setting and humidity.
2 Adjust the temperature set-
ting.
3 To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following situations.

No passengers are detected
in the rear seats
 The windshield defogger is
not operating
While operating, the indicator illumi-
nates on the S-FLOW mode switch.
■Manually turning front seat
concentrated airflow mode
on/off
In front seat concentrated air-
flow mode, directing airflow to
the front seats only and to all
seats can be switched via switch
operation. When the mode has
been switched manually, auto-
matic airflow control stops oper-
ating.
Select on the main con-
trol screen or press the S-FLOW
mode switch on the air condi-
tioning operation panel and
switch the airflow.
 Indicator illuminated: Airflow
to the front seats only
 Indicator off: Airflow to all the
seats
■Operation of automatic airflow
control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the hybrid system is
started and at other times depend-
ing on the outside temperature.
●After the hybrid system is started,
if passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accura tely detect the
