■Noise from air conditioning sys-
tem
Approximately 90 seconds after the
power switch turned to OFF, you
may hear sound coming from air
conditioning system. This is the
sound of a air conditioning system
initialize and, it doe s not indicate a
malfunction.
■Customization
Some functions can be customized.
(Customizable features: P.580)
1 Press the “AUTO” 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.

WARNING
■Cautions for using “My Room
Mode”
Do not leave children, people who
need assistance, or pets inside
the vehicle. The system may turn
off automatically and the interior
temperature may become high or
low, resulting in heat stroke, dehy-
dration or hypothermia. Failure to
do so may result in death or seri-
ous injury.
■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 def oggers 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 To yota dealer.
When a part of the air condition-
ing system, such as the evapora-
tor, is to be repl aced, it must be
replaced with a new one.

■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.
■Windshield fog d etection func-
tion
When automatic mode is set, the
humidity sensor detects fog on the
windshield and controls the air con-
ditioning system to prevent fog.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. When the front pas-
senger seat is not occupied, air-
flow may switch to only the
driver’s seat. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following
situations.

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 condition-
ing 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
presence of passengers and auto-
matic airflow co ntrol will not oper-
ate.
■Operation of manual airflow
control
Even if the funct ion is manually
switched to directing airflow to only
the front seats, w hen a rear seat is
occupied, it may automatically direct
airflow to all seats.

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 defog-
ging.
NOTICE
■Humidity sensor
In order to detect fog on the wind-
shield, a sensor which monitors
the temperature of the windshield,
the surround humidity, etc. is
installed.
Follow these points to avoid dam-
aging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner
on the sensor or subject it to
strong impacts
●Do not stick anything on the
sensor

If the Remote Air Conditioning
System is used while the AC
charging cable is connected to
the vehicle, electricity from an
external power source can be
used minimizing the drop in
charge of the hybrid battery
(traction battery).
Charging will be conducted auto-
matically after the Remote Air Con-
ditioning System is stopped.
Check the temperature setting
of the air conditioning system.
( P.396)
The Remote Air C onditioning Sys-
tem will operate in accordance with
the temperature settings of the air
conditioning system.
Press and hold “A/C” on the
wireless remote control to oper-
ate the Remote Air Conditioning
System.
The system can be stopped by
pressing “A/C” twice.
■Operating conditions
The system will only o perate if all of
the following conditions are met:
●The shift lever is in P.
●The power switch is off.
●All doors are closed.
●The hood is closed.
■Remote Air Conditioning Sys-
tem automatic shut-off
The system will automatically shut
off under the follo wing conditions:
●About 20 minutes have passed
since operation began
●Any one of the operating condi-
tions is not met
The system may also shut off if the
charge level of the hybrid battery
(traction battery) drops to low.
■Conditions affecting operation
The system may not start in the fol-
lowing situations:
●The charge level of the hybrid bat-
tery (traction battery) is low
●The outside temperature is
extremely low
●When the hybrid system is cool
(for example , after being left for a
long time in low temperatures)

cient due to the power being
restricted more than during normal
air conditioning operation. Also, the
outside of the windshield may fog up
due to the outside temperature,
humidity or air conditioning set tem-
perature.
■Using the heater via the Remote
Air Conditioning System
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
●When the outside heat exchanger
becomes frosted over, heating
performance may decline due to
automatically switching to the frost
removal operation. ( P.396)
■Security feature
Any unlocked doors will be automat-
ically locked when the system is
operating. The buzzer sounds and
the emergency flashers flash to indi-
cate that the doors have been
locked or the system has been
turned off.
■Conditions affecting operation

■While the Remote Air Condi-
tioning System is operating
●Depending on the operating con-
dition of the Remote Air Condition-
ing System, the air conditioning
compressor or cooling fan may
spin and an operating noise may
be heard. However, this does not
indicate a malfunction.
●The air conditioning operation
switches, etc. will not operate
while the Remote Air Condition-
ing System is operating.

WARNING
■Precautions for the Remote
Air Conditioning System
●Do not use the system if people
are in the vehicle.
Even when the system is in use,
the internal temperature may
still reach a high or low level
due to features such as the
automatic shut-off. Children and
pets left inside the vehicle may
suffer heatstroke dehydration or
hypothermia or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than e xpected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when neces-
sary.
●Do not operate “A/C” on the
wireless remote control if the
hood is open. The Remote Air
Conditioning System may oper-
ate unintentionally and objects
may be drawn into the electrical
cooling fan.
NOTICE
■To prevent the hybrid battery
(traction battery) from being
discharged
Use “A/C” on the wireless remote
control only when necessary.
