Directional Controls When the air conditioner compressor is on, you may sometimes notice slight changes in your vehicle's engine performance and power. This is normal, because the system is designed to help fuel economy whileit maintains the desired cooling level. The air conditioner removes moisture from the air, so you may sometimes notice water dripping from under your vehicle when it is idling or after it has been turned off. This is normal. On very hot days, your vehicle will cool down more quickly and economically if you open the windows long enough to let hot inside air escape. For all settings, adjust the temperature control lever and fan speed as desired. RECIRC (Recirculate): Press to get maximum cooling or quick cool-down on very hot days. This setting recirculates much of the air inside your vehicle. It should not be used for long periods of time because the air may become too cold and dry. Slide the temperature control lever down to the coolest setting and adjust the fan speed as desired. UPPER: For normal cooling on hot days, press A/C along with UPPER. This setting cools outside air and directs it through the instrument panel outlets. Adjust the temperature of the air with the temperature control lever. BI-LEV (Bi-Level): This setting is designed for use on sunny days when the air is only moderately warm or cool. On days like these, the sun may adequately warm your upperbody, but your lower body may not be warm enough. The BI-LEV setting directs outsideair into your vehicle in two ways. Cooler air is directed toward your upper body through the front instrument panel outlets, while warmed air is directed through the heater ductsat your feet. At times this temperature differencemay be more apparent than others. For best results, slide the temperature control lever to the middle position, and then adjust for comfort.
