Function Buttons These buttons control the climate control ON/OFF, air intake, front defrost, rear defrost and the air conditioning operation. OFF: Press the OFF button to turn off the climate control system. This is the only setting that fully shuts off the fan. The digital display will show only the outside temperature. You can still adjust the driver set temperature, the passenger temperature offset and the air intake mode while in OFF. A/C (Air Conditioning): This button turns the air conditioning compressor off or on under most conditions. The light on the A/C button will come on when the compressor is operating in either the automatic or manual mode. The air conditioning does not operate at temperatures below approximately 35_F to 40_F (2_C to 4_C). The light on the A/C button will flash if pressed when air conditioning is not available. The air conditioning cools and dehumidifies the air coming into the vehicle. 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. If the system is operating in the AUTO mode, turning the air conditioning off will delete AUTO from the digital display and show current mode and fan settings. The AUTO button must be pressed to return to the automatic mode operation. The air conditioning may be forced off at high engine speeds or high engine oil or coolant temperatures. (Outside Air): Press this button to provide outside air. The light on this air intake button will come on to show when it is operating. When in the AUTO mode, the system automatically selects outside air instead of recirculate, as required, to control the temperature in the vehicle. By pressing outside air, the system will lock into the outside air mode. Any adjustment to the air intake must then be made manually. Outside air should be used when trying to defrost or defog windows to help reduce moisture inside of the vehicle. 3-8
