yellowblue Air Conditioning On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. The climate control system will cool and dehumidify the air inside the vehicle. While in the automatic operation mode, the system will use recirculation as necessary to cool the air. You may also need to adjust the interior temperature. Turn either the TEMP/AUTO or TEMP/OFF knob clockwise to increase the temperature or counterclockwise to decrease temperature. Adjust the fan speed as needed. In order to obtain the maximum cool setting, both the driver's TEMP/AUTO knob and the passenger's TEMP/OFF knob must be turned to 60_F (16_C). Outside air will be brought in and sent through the floor outlets. The heater works best if you keep the windows closed while using it. In order to obtain the maximum heat setting, both the driver's TEMP/AUTO knob and the passenger's TEMP/OFF knob must be turned to 90_F (32_C). Defrosting Use defrost to remove fog or ice from the windshield quickly in extremely humid or cold conditions. Pressing the defrost button on the control panel (located above the rear window defogger button) automatically turns the fan blower to high speed. Make sure that the side air vents are opened. Turn both the TEMP/AUTO knob and the TEMP/OFF knob clockwise as needed to adjust the temperature. To warm the foot area while in defrost, press the MODE button until the heater/defrost symbol appears (see "Manual Operation" earlier in this section). Note: Recirculation is not available in the defrost mode. Heating Adjust the interior temperature to your comfort level by turning the TEMP/AUTO knob or the TEMP/OFF knob clockwise to increase the temperature or counterclockwise to decrease the temperature. If the fan speed needs adjusting, press the up or down arrow. 3-6
