5-1. Using the air conditioning system and defogger

outside rear view mirrors.
Press the rear window and out-
side rear view mirror defoggers 
switch.

The defoggers will automatically 
turn off after 15 minutes.
When the rear window and outside 
rear view mirror defoggers switch is 
on, the indicator illuminates on the 
rear window and outside rear view 
mirror defoggers switch.

■

When the outside temperature 

exceeds 75°F (24°C) and the air 

conditioning system is on

●

In order to reduce the air condi-

tioning power consumption, the air 

conditioning system may switch to 

recirculated air mode automati-

cally.

This may also reduce fuel con-

sumption.

●

Recirculated air mode is selected 

as a default mode when the power 

switch is turned to ON.

It is possible to switch to outside air 

mode at any time by pressing the 

outside air mode switch.

■

Fogging up of the windows

●

The windows will easily fog up 

when the humidity in the vehicle is 

high. Turning the cooling and 

dehumidification function on will 

dehumidify the air from the outlets 

and defog the windshield effec-

tively.

●

If you turn the cooling and dehu-

midification function off, the win-

dows 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 

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 recirculated air 

mode temporarily is recom-

mended in preventing 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 depending on 

the temperature setting or the 

inside temperature.

■

When the outside temperature 

falls to nearly 32°F (0°C)

The dehumidification function may 

not operate even when “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.

●

In order to suppress odors that 

occur when the air conditioning 

system starts, the air flow mode 

may change to blow air to the feet 

or air may stop blowing for a short 

period of time immediately after 

the air conditioning system is 

started in automatic 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.

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.

5-1. Using the air conditioning system and defogger

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,

■

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.

Press 

 on the air conditioning 

operation panel and switch the 
airflow.

■

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 accurately detect the 

presence of passengers and auto-

matic airflow control will not oper-

ate.

■

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 direct 

airflow to all seats.

■

To return to automatic airflow 

control

1

With the indicator off, turn the 

power switch off.
