When you select position, the system automatically turns on the outside (fresh) air mode.

• For maximum defrosting, set the temperature control knob to the extreme right/hot position and the fan speed control knob to the highest speed.
• If warm air to the floor is desired while defrosting or defogging, set the mode selection knob to the position.
• Before driving, clear all snow and ice from the windshield, rear window, outside rear view mirrors, and all side windows.
• Clear all snow and ice from the hood and the air inlet in the cowl grille to improve heater and defroster efficiency and to reduce the probability of fogging on the inside of the windshield.

The difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up, causing loss of visibility. In this case, set the mode selection knob to the position and fan speed control knob to the lower speed.

If you don’t want outside (fresh) air when operating in either of these modes, air intake control switch again will deactivate the outside (fresh) air mode.
