: (Outside Air): Press this button to turn the outside air mode on. When this mode is on, outside air will circulate throughout your vehicle. When the button is pressed, an indicator light in the button will come on to let you know that it is activated. The outside air mode can be used with all modes, but it cannot be used with the recirculation mode. You may have to set the instrument panel brightness control to the highest setting during the day to see the indicator lamp. # (Air Conditioning): Press this button to turn the air conditioning system on or off. When A/C is pressed, an indicator light will come on to let you know that the air conditioning has been activated. You may have to set the instrument panel brightness control to the highest setting during the day to see the indicator lamp. On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. For quick cool down on hot days, do the following: 1. Select the vent mode. 2. Select the recirculation mode. 3. Select A/C. 4. Select the coolest temperature for both zones. 5. Select the highest fan speeds. Using these settings together for long periods of time may cause the air inside of your vehicle to become too dry. To prevent this from happening, after the air inside of your vehicle has cooled, turn the recirculation mode off. 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. ? (Recirculation): This mode keeps outside air from coming in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or help heat or cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on. When the button is pressed, an indicator light will come on. You may have to set the instrument panel brightness control to the highest setting during the day to see the indicator lamp. The recirculation mode cannot be used with outside air modes.
