AUTO With this setting, the airconditioning compressor cycles when needed to cool the air andit's all automatic. In cold weather when the system senses the need for heat, the airflow will be directed out the floor ducts. As the interior temperature approaches the desired setting, the blower speed will decrease and the airflow could be directed through defroster and floor the ducts. To maintain interior comfort, the airflow may moveto the instrument panel air outlets and floor ducts (Bi-Level). On bright sunny days in cold weather, the airflow maycome out of the A/C outlets (Bi-Level mode) tomaintain comfort and preventstuffiness. Electronic Climate Control Features A/C PURGE If your vehicle is sitting out ona hot day and you have it set on AUTO, a the air will first flow out thefloor air ducts for few seconds. That is normal. Thisis to expel hot air in the airducts. As the air is cooled, the flow will move through the A/C outlets. If you start your vehicle withthe fan setting on HIit will skip the A/C Purge. COLD WEATHER PURGE On cold days when your system is first turned on,in either theAUTO or ECON setting, and the fan settingis not onHI, a small amount of air will flow through the defroster duct while the system is waitingfor the engine coolant to warm up enough to provide heat. This prevents your breath from fogging your windshield. As the coolant warms up, the blower fan speed will gradually increaseandair willflow from the heater outlets, with some airflow to thewindshield to prevent fogging under most normal conditions. MANUALLY RECIRCULATE INSIDE AIR There may be times when you want less air fromthe outside. To recirculate the air from the inside, in the AUTO setting, just set the temperature to60" F ( 1 6 O C ) and adjust your fan speed. 3-4
