222 UNDERSTANDING YOUR INSTRUMENT PANEL Temperature Control Use this control to regulate the temperature of the air inside the passenger compartment. The blue area of the scale indicates cooler temperatures while the red area indicates warmer temperatures. Circulation Control Use this button to choose between outside air intake or recirculation of the air inside the vehicle. A light will illuminate when you are in recirculate mode. Only use the recirculate mode to temporarily block out any outside odors, smoke, or dust and to cool the interior rapidly upon initial start up in very hot or humid weather. NOTE: Continuous use of the recirculate mode may make the inside air stuffy and window fogging may occur. Extended use of this mode is not recommended. In cold or damp weather, the use of the Recirculate position will cause windows to fog on the inside because of moisture build up inside the vehicle. For maximum defogging, select the Outside Air position. NOTE: If your air conditioning performance seems lower than expected, check the front of the A/C condenser, located in front of the radiator, for an accumulation of dirt or insects. Clean with a gentle water spray from behind the radiator and through the condenser. Fabric front fascia protectors may reduce air flow to the condenser, reducing air conditioning performance.
