Using automatic mode

Fan speed is adjusted automatically according to the temperature setting and ambient conditions. As a result, the following may occur:

• The system may switch automatically to recirculated air mode when the coolest temperature setting is selected when the ambient temperature is high.

• Immediately after the switch is pressed, the fan may stop for a while until warm or cool air is ready to flow.

• Cool air may flow to the area around the upper body when the heater is on.

Switching between outside air and recirculated air modes

Recirculated air mode or outside air mode may be automatically switched to in accordance with the temperature setting, the outside temperature, etc.

When the outside temperature exceeds 75°F (24°C) and the air conditioning system is on

• In order to reduce the air conditioning power consumption, the air conditioning system may switch to recirculated air mode automatically. This may also reduce fuel consumption.

• Recirculated air mode is selected as a default mode when the engine switch is turned to the “ON” position (vehicles without a smart key system) or the “ENGINE START STOP” switch is turned to IGNITION ON mode (vehicles with a smart key system).

• It is possible to switch to outside air mode at any time by pressing .

Using the system in recirculated air mode

The windows will fog up more easily if recirculated air mode is used.

Window defogger feature

Recirculated air mode may automatically switch to outside air mode in situations where the windows need to be defogged.

outlets used

For your driving comfort, air flowing to the feet may be warmer than air flowing to the upper body depending on the temperature setting.

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.

When outside air temperature is below 32°F (0°C)

The cooling and dehumidification function may not operate even when is pressed.

When the indicator light on

Press to turn off the cooling and
dehumidification function and turn it on again. There may be a problem in the air conditioning system if the indicator light continues to flash. Turn the air conditioning system off and have it inspected by your Toyota dealer.

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 automatic mode.


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 windshield can cause the outer surface of the windshield to fog up, blocking your vision.


To prevent battery discharge

Do not leave the air conditioning system on longer than necessary when the engine is stopped.
