? (Recirculation): Press the left side of the button to turn the recirculation mode on. When recirculation mode is selected, the air inside the vehicle will be recirculated through the climate control system and the vehicle, not from outside your vehicle. This mode is helpful when you are trying to limit odors from entering your vehicle and for maximum air conditioning performance in hot weather. When the button is pressed, an indicator light above the button will come on to let you know that it is activated. The recirculation indicator light will blink three times if you try to use recirculation in a mode that it can not be used in. Only use this mode when it is needed for comfort, since window fogging will rapidly occur if the air conditioning compressor is not engaged. Pressing this button will cancel the outside air mode. When you switch to the defog or defrost modes the system will automatically move from recirculation to outside air. When the vehicle or fan is turned off and back on, the system will default to outside air automatically. Only use recirculation mode when it is needed for comfort, since window fogging may occur. Temperature Control: Turn the center knob clockwise or counterclockwise to increase or decrease the temperature inside your vehicle. When it's cold outside 0°F (−18°C) or lower, use the engine coolant heater, if equipped, to provide warmer air faster to your vehicle. An engine coolant heater warms the coolant that the engine uses to provide heat to warm the inside of your vehicle. For more information, see Engine Coolant Heater on page 125. # (Air Conditioning): Press this button to turn the air conditioning system on or off. When the air conditioning button is pressed, an indicator light will come on to let you know that air conditioning is activated. The air-conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. 190
