For details about air flow selector settings, see the illustration after "A/C" button. Air intake selector The air intake selector button is used to switch the air intake FRESH mode that draws outside air into the system and RECIRCULATE mode that recirculates the air inside vehicle. To turn the air source to RECIRCULATE mode, press the button. The indicator will come on. To turn the air source to FRESH mode, press the button again. The indicator will go off. To prevent fogging up of the windshield, the air intake mode may change automatically to FRESH depending on the condition of the air conditioning system. "A/C" button To turn on the air conditioning, press the "A/C" button. The "A/C" button indicator will come on. To turn the air conditioning off, press the button again. If the "A/C" button indicator flashes, there is a problem in the air conditioning system and the air conditioning automatically shuts off. If this happens, take your vehicle to a Toyota dealer for service. Windshield air flow button When this button is pressed, air flows mainly from the windshield vents and turns on the defogging function with the purpose of clearing the front view. Pressing this button once again returns the air flow mode to the last one used. This button allows the air intake to select FRESH automatically. This is to clean up the front view more quickly. If you want to return the setting to RECIRCULATE mode, press the air intake selector button once again. Press the "A/C" button for dehumidified heating or cooling. This setting clears the front view more quickly. 194 2002 MY SIENNA_U (OM45407U)
