h (Recirculate): Press this button to prevent outside air and odors from entering the vehicle or to help heat or cool the air inside the vehicle more quickly. An indicator light above the button will come on in this mode. The air conditioning compressor also comes on. This mode is not available for floor, defog and defrost modes. When the recirculation button is pressed, the recirculate indicator light will flash five times and outside air will be delivered. Operation in this mode during periods of high humidity and cool outside temperatures may result in increased window fogging. If window fogging is experienced, select the defrost mode. Outside Air: This mode allows outside air to circulate through the vehicle. This mode is automatically active if recirculate is not selected. There is no button for outside air. On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. For quick cool down on hot days: 1. Select the vent mode. 2. Select the recirculation mode. 3. Select air conditioning. 4. Select the coolest temperature. 5. Select the highest fan speed. Using these settings together for long periods of time may cause the air inside of the vehicle to become too dry. To prevent this from happening, after the air in the vehicle has cooled, turn off the recirculation by pressing the button again. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. The air conditioning compressor cannot be turned on when the fan is off. # (Air Conditioning): If your vehicle has air conditioning, press this button to turn the air conditioning system on or off. When this button is pressed, an indicator light above the button will come on to let you know the air conditioning is activated. 155
