186 UNDERSTANDING YOUR INSTRUMENT PANEL on the outer edge of each instrument panel outlet grille opens or closes a shutter to turn airflow on or off through that outlet. NOTE: For maximum airflow to the rear seat passengers, the center instrument panel outlets can be aimed, so that the left center outlet is directed toward the right rear passenger and the right center outlet is directed toward the left rear passenger. 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. 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. Circulation Control Use this control to choose between outside air intake or recirculation of the air inside the vehicle. 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.
