Air Conditioning (If Equipped) On very hot days, open the windows long enough hot, to let inside a r escape. This reduces the time it takes for your i vehicle to cool down, which should help fuel economy. For quick cool-down on very hot days, use MAX with the temperature knob all the way in the blue area. If this setting is used for long periods of time, the air in your vehicle may becometoo dry. For normal cooling on hot days, use VENT with the temperature knob in the blue area and the A/C button pushed in. Thesystem will bring inoutside 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. You can use BI-LEVEL with the temperature knob in the middle and the A/C button pushedin. The system will bring in outside air and direct slightly warmer air to your lower body. You may notice this temperature difference more at some times than others. Heating On cold days, use FLOOR with temperature knob all the the way in the red area. Thesystem will bring in outside air, heat it and sendit to the floor ducts. Your vehicle has heatducts that are directed toward the rear seat. Keep the area under the front seats clear of obstructions so the heated aircan reach the rear seat passengers. If your vehicle has an engine coolant heater, you canuse 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 thecoolant your engine and heating system useto provide heat. See "Engine Coolant Heater" in the Index.
