Heating and Cooling To Heat To warm the interior, press and Set the fan to the desired speed. Adjust the warmth of the air with the temperature control lever. To warm the interior rapidly after the car has been sitting out in cold weather: 1. Start the engine. 2. Select and 3. Slide the temperature control lever to maximum heat. 4. Leave the fan OFF for the first few minutes. When the temperature gauge rises above the bottom white mark, set the fan to medium speed. 5. When the interior warms up, switch to fresh air mode and adjust the temperature control lever to a comfortable setting. To Defrost To remove 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 and 3. Set the fan and temperature controls to maximum. These settings direct all the air flow to the defroster vents at the base of the windshield and the side window defroster vents. The air flow will get warmer and clear the windows faster as the engine warms up. You can close the side and upper vents with the dial beside each vent. That 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 only shut the system completely off 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
