Heating and Cooling How to Use the System This section covers the best way to use the system for ventilation, cooling, dehumidifying, defrosting and heating. In most cases, the mode and air source selections are only recommendations. You may prefer different settings. Use mode to heat or cool the interior more quickly, or to keep out smoke and dust. Leaving the system in recirculation mode with the air conditioning off can cause the windows to fog up. Switch to mode as soon as the interior reaches a comfortable temperature or the outside smoky, dusty condition clears. The engine must be running for the heater and air conditioning system to provide hot and cold air. The heater uses engine coolant to warm the air. If the engine is cold, it will be several minutes before you feel warm air circulating. Air conditioning does not depend on engine temperature. It can produce cold air almost immediately. Controlling Air Flow Direction Air flows into the interior at three levels: Toward the floor through the dash vents and toward the windshield and side windows You select the air flow level or combination of levels with the five mode buttons. Ventilation Your car has a flow-through ventilation system. Air enters the car through vents in front of the windshield. It circulates through the interior then exits through vents near the rear window. This system provides fresh air even when the car is standing still. To bring in outside air, press the button. Set the fan at a comfortable speed. continued Comfort and Convenience Features
