Air Conditioning On hot days, open the windows long enough to let hot inside air escape. Thisreduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditionerto work its best. For quick cool-down on very hot days, use MAX A/C with the temperature knob turned counterclockwise. This setting should be used to keep odors and/or dust from entering the vehicle. For normal cooling on hot days, use A/C with the temperature knob turned counterclockwise. On cool but sunny days, use BI-LEVEL A/C to deliver warm air to the floor and cooler airto the instrument panel outlets. When the air conditioneris on, you may sometimes notice slight changes in your vehicle's engine speed and power. This is normal because the system is designed to cyclethe compressor onand off to keep the desired temperature. Heating The heater works best if you keep your windows closed while using it. On cold days, use HEATER with the temperature knob turned clockwise. BLEND is useful in cool weather when you have fog or ice on the windshield or side windows. If you use the optional engine coolant heater before starting your engine, your heating system will produce warmer air fasterto heat the passenger compartment in cold weather. See "Engine Coolant Heater" in the Index. Ventilation System For mild outside temperatures when little heating or cooling is needed, use VENT to direct outside air through your vehicle. Airflow is through the instrument panel outlets. Your vehicle's ventilation system supplies outside air to the inside of your vehicle when it ismoving. When the vehicle is not moving, you can get outside air to flow through by selecting any mode and any fan speed. 3-3
