Using the automatic mode
Fan speed is adjusted automatically in 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
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.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior.
During cooling operation, setting the recirculated 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 0C (32F)
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 conditioning system if the indicator light
goes off again. Turn the air conditioning system off and have it inspected by
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
Air conditioning odors
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 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.
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.
Air conditioning filter
P. 502
CAUTION
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.

Power heater
: If equipped
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 com-
pletely.
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.
This feature is used to keep the cabin warm in cold conditions.
Turns the power heater on/off
The power heater turns on
about 25 seconds after the but-
ton is pressed, and takes
about another 85 seconds to
warm up.

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 duly 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.
