On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for the vehicle to cool down. Then keep the windows closed for the air conditioner to work its best. On cool, but sunny days while using manual operation of the automatic system, use bi-level to deliver warm air to the floor and cooler air to the instrument panel outlets. To warm or cool the air delivered, press the temperature buttons to the desired setting. In AUTO mode the system cools and dehumidifies the air inside the vehicle. Also while in AUTO mode, the system maximizes its performance by using recirculation as necessary. Heating: On cold days when using manual operation of the automatic system, use floor mode to deliver air to the floor outlets. To warm or cool the air delivered, press x or w to the desired temperature setting. To use the automatic mode, turn the knob to AUTO and press x or w to adjust the temperature. h (Recirculation): Press to turn the recirculation mode on. An indicator light above the button comes on to show it is on. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to help prevent outside air and odors from entering the vehicle. The recirculation indicator light blinks three times if you try to use recirculation in a mode in which it cannot function. Pressing this button cancels the auto recirculation feature. Each time the vehicle is started, the system reverts to the auto recirculation function. The recirculation mode cannot be used with the floor, defrost, or defog modes. If recirculation is selected in these modes, the indicator flashes three times and turns off to indicate that this is not allowed. This is to prevent window fogging. When the weather is cool or damp, operating the system in recirculation for extended periods of time can cause fogging of the vehicle's windows. To clear the fog, select either defog or defrost. Make sure the air conditioning is on. Allow the air conditioning to run automatically to help dehumidify the air. : (Outside Air): Press to turn the outside air mode on. An indicator light comes on to show it is on. Air from outside the vehicle will circulate throughout the vehicle. The outside air mode can be used with all modes, but it cannot be used with the recirculation mode. Pressing this button cancels the recirculation mode. 3-26
