Using the air conditioning system

Adjusting the temperature setting

To adjust the temperature set- ting, turn the temperature con- trol dial clockwise (warm) or counterclockwise (cool).

If is not pressed, the system will blow ambient tem- perature air or heated air.

For quick cooling, turn the tem- perature control dial to the “MAX A/C” position.

The air conditioning will automatically turn on and the air intake selector will be set to recirculated air mode.

: If equipped

Fan speed setting

Turning the dial to “OFF” turns off the fan.

Change the airflow mode

The positions between the air outlet selections can also be selected for more delicate adjustment.

Other functions

Switching between outside air and recirculated air modes (P. 342)

Defogging the windshield (P. 342)

Switching between outside air and recirculated air modes

Press .

The mode switches between outside air mode (introduces air from outside the vehicle) (indicator off) and recirculated air mode (recy- cles air inside the vehicle) (indicator on) each time the button is pressed.

Defogging the windshield

Defoggers are used to defog the windshield and front side win- dows.

Set the air outlet selector dial to position.

Set the outside/recirculated air mode button to outside air mode if the recir- culated air mode is used. (It may switch automatically.)

To defog the windshield and the side windows early, turn the air flow and temperature up.

Defogging the back window (CrewMax models)

The defogger will automatically turn off after approximately 15 minutes.

Defogging the outside rear view mirrors (if equipped)

Press or .

The defogger will automatically turn off after approximately 15 minutes. CrewMax models: Turning the back window defogger on will turn the out- side rear view mirror defoggers on.

Windshield wiper de-icer (if equipped)

Press or .

The defogger will automatically turn off after approximately 15 minutes. Double Cab models: Turning the outside rear view mirror defoggers on will turn the windshield wiper de-icer on.

Front

Open the vent Close the vent

Rear (CrewMax models)

Direct air flow to the left or right, up or down.

Turn the knob to open or close the vent.

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.

When driving on dusty roads

Close all windows. If dust thrown up by the vehicle is still drawn into the vehi- cle 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 recommended in prevent- ing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high.

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

In order to reduce the air conditioning power consumption, the air condition- ing 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 in ON.

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

When the outside temperature falls to nearly 32°F (0°C)

The dehumidification function may not operate even when is pressed.

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 conditioning system be set to outside air mode prior to turning the vehicle off.

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.

Do not place anything on the instrument panel which may cover the air outlets. Otherwise, air flow may be obstructed, preventing the windshield defoggers to defog.

To prevent burns (vehicles with rear view mirror defoggers and wind- shield wiper de-icer)

Do not touch the rear view mirror surfaces when the outside rear view mir- ror defoggers are on.

Do not touch the glass at lower part of the windshield or to the side of the front pillars, when the windshield wiper de-icer is on.
