Dehumidified defrosting or defogging

front defroster
button on.(The indicator light on the button will remain in Off.)

- When the
front defroster
button is pressed, the air conditioner will automatically be turned on at outside temperatures above 36°F (2°C) (The indicator light may not illuminate). The air recirculate mode automatically turns off, allowing outside air to be drawn into the passenger compartment to further improve the defogging performance.
Cooling and/or dehumidified heating (AUTO)
This mode may be used all year round as the system automatically works to keep a constant temperature. Air flow distribution and fan speed are also controlled automatically.
- Press the AUTObutton on. (The indicator on the button will illuminate and AUTO will be displayed.)

- A visible mist may be seen coming from the vents in hot, humid conditions as the air is cooled rapidly. This does not indicate a malfunction.
- You can individually set driver’s and front passenger’s side temperature using each set of temperature control buttons. When the DUAL button or passenger’s side temperature control buttons are pressed, the DUAL indicator will come on. To turn off the passenger’s side temperature control, press the DUAL button.
