For normal cooling on hot days, use the vent outlets and outside air with the air conditioning. The system will bring in outside air and cool it. On cool but sunny days, the sun may warm your upper body, but your lower body may not be warm enough. To remedy this, you can use bi-level with the air conditioning on. The system will bring in outside air and direct it to your upper body, while sending slightly warmed air to your lower body. You may notice this temperature difference more at some times than others. Heating On cold days use the floor mode and the temperature turned toward red, with a high fan setting. The system will bring in outside air, heat it and send it to the floor ducts. If your vehicle has an engine coolant heater, you can use it to help your system provide warm air faster when it's cold outside (0_F (-18_C) or lower). An engine coolant heater warms the coolant your engine and heating system use to provide heat. See "Engine Coolant Heater" in the Index. Ventilation For mild outside temperatures when little heating or cooling is needed, use the vent outlets, a fan setting, ECON and outside air to direct outside air through your vehicle. Your vehicle also has the flow-through ventilation system described later in this section. Defogging and Defrosting Your system has two settings for clearing the front and side windows. To defrost the windows quickly, use the defrost button. To warm passengers while keeping the windows clean, select defog by pressing the MODE button. 3-9
