■Using automatic mode
Fan speed is adjusted automatically 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 is pressed.
■ 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 wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculat ed 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.
■ When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when is pressed.
■ When the indicator light on goes off by itself
Press to turn off the dehumidification function and turn it on again.
There may be a problem in the air condi tioning system if the indicator light
goes off again. Turn the air conditioning system off and have it inspected by
any authorized Toyota dealer or re pairer, or another duly qualified and
equipped professional.

■ Ventilation and air conditioning odors
● To let 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.
● To reduce potential odors from occurring:
• It is recommended that the air condi tioning system be set to outside 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 conditioning system is started in AUTO mode.
■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with a Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the auto-
matic air conditioning cooling, heating and dehumidification functions turn off
and the fan speed is decreased according to the outside temperature etc. or
air blowing stops. To stop the air conditioning system from turning off, press
the Stop & Start cancel switch and refrain from using the Stop & Start system.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.

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 wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
■ When the outside rear view mirror defoggers (if equipped) are on
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
engine is stopped.

25 seconds after the switch is
pressed, and takes about another
85 seconds to warm up.
■ Power heater can be operated when
The engine is running.
■ Normal characteristics of power heater operation
The following cases do not indicate a malfunction:
● When the power heater is turned on or off, some white smoke and a slight
odor may be emitted from the power heater exhaust that is located under
the floor.
● When the power heater is used under extremely cold conditions, vapor may
be visible from its exhaust.
● When the power heater is turned off, you may hear a sound in the engine
compartment for about 2 minutes until the power heater turns off completely.
■ After the heater is turned off
We recommend not restarting the heater for 10 minutes after you turn it off.
Otherwise, a noise may be heard as the heater ignites.
■ When refueling your vehicle
The engine must be turned off. Turning the engine off turns the power heater
off.

WARNING
■To prevent burns or damage to your vehicle
NOTICE
■To prevent damage to your vehicle
● Do not turn the heater on and off repeatedly in 5 minute intervals as this
can shorten the life of the heater components. If the engine must be turned
on and off repeatedly within short intervals (such as when the vehicle is
being used for delivery purposes), turn the heater off.
● Do not modify or open the heater without consulting any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional, as
this may cause a heater malfunction or a fire.
● Be careful not to splash or spill liquid directly on the heater or on the
heater fuel pump, as this may cause the heater to malfunction.
● Keep the intake and exhaust pipes of the heater free from water, snow,
ice, mud, etc. If the pipes become clogged, this can cause the heater to
malfunction.
● If you notice anything unusual, such as a fluid leak, smoke and poor oper-
ation, turn off the heater and have your vehicle checked by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
● Do not touch the heater or its exhaust
pipe as they are hot. You may burn
yourself.
● Keep flammable items such as fuel
away from the heater and its exhaust
pipe, as this may cause a fire.
