UP - atm When the system is set for AUTO, the system adjusts automatically to changes in temperature to maintain your temperature setting. The system may supply cooler air to the side towards the sun. Air will come from the floor, middle and windshield outlets. The fan speed will vary as the system maintains the selected temperature setting. To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available.
