Pressing the arrows will delete AUTO from the digital display. The fan graphics with the fan speed bars will be shown. To increase the fan speed so that more air flows into the vehicle, press the up arrow on the fan switch. To decrease the fan speed and airflow, press the down arrow. The AUTO button must be pressed to return to the automatic fan control. If the airflow seems low when the fan speed is at the highest setting, the passenger compartment air filter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 184 and Scheduled Maintenance on page 433. ^ (Air Conditioning Off): Press this button to turn the air conditioning compressor off. Press AUTO to return to automatic operation. When in AUTO, the air conditioning compressor will come on automatically, as needed. Air conditioning does not operate at temperatures below about 35°F to 40°F (2°C to 4°C). In temperatures above 40°F (4°C), the air conditioning cannot be turned off in defrost and defog, as it helps to remove moisture from the vehicle. It also helps to keep the windows clear. You may notice a slight change in engine performance when the air-conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. 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. ? (Recirculation): Press this button to turn the recirculation mode on or off. When the climate control system is in recirculation mode an indicator light will come on. This mode prevents outside air from entering your vehicle. It can be used to prevent outside air and odors from entering your vehicle and to help cool the air inside your vehicle more quickly. Recirculation mode is not available in defrost or defog mode. 180
