Heating and Cooling To Defog and Defrost To remove fog from the inside of the windows: 1. Switch the fan on. 2. Turn on the air conditioning. 3. Select the Fresh Air mode and 4. Adjust the temperature control lever so the air flow from the defroster vents feels warm. 5. Turn on the rear window defogger to help clear the rear window. To remove exterior frost or ice from the windshield and side windows after the car has been sitting out in cold weather: 1. Start the engine. 2. Select the Fresh Air mode and 3. Switch the fan and temperature controls to maximum. To rapidly remove exterior frost or ice from the windshield (on very cold days), first select the Recirculation mode. Once the windshield is clear, select the Fresh Air mode to avoid fogging the windows. These settings direct all the air flow to the defroster vents at the base of the windshield and the side windows. The air flow will get warmer and clear the windows faster as the engine warms up. You can close the corner vents with the dial beside each vent. This will send more warm air to the windshield defroster vents. For safety, make sure you have a clear view through all the windows before driving away. To Turn Everything Off To shut off the system temporarily, slide the fan speed and temperature control levers all the way to the left. You should shut the system completely off only for the first few minutes of driving in cold weather, until the engine coolant warms up enough to operate the heater. Keep the fan on at all other times so stale air does not build up in the interior. Comfort and Convenience Features
