yellowblue Manual Operation You may also manually adjust the air delivery or fan speed. AIR FLOW: This button is used to change the direction of the airflow. The airflow choices available are WINDSHIELD-FLOOR, MID, MID-FLOOR, and FLOOR. If the system is set for AUTO, pressing the AIR FLOW button will display and hold the current airflow direction and the comfort setting. Press the AIR FLOW up or down button again to change the direction of the airflow. If the AIR FLOW up button is selected while in the FRONT defrost mode, the system will direct the air toward the windshield and the floor. If the AIR FLOW down button is selected while in the FRONT defrost mode, the system will direct the air toward the floor, and the FRONT defrost mode will cancel. Notice the arrows in the display. OFF: If the passenger comfort control is turned on, it can be turned off by pressing the OFF button once. Pressing the OFF button a second time will turn off the main system. Turning off the main system causes the fan to turn off and the airflow to be directed toward the floor. The system will still try to keep the interior of the vehicle at the previous chosen comfort setting. The outside temperature will show on the display when the system is OFF. The ventilation system always allows fresh air to flow through your vehicle when the vehicle is moving even with the system in the OFF mode. VENT: The VENT button allows outside air to flow through your vehicle without the air conditioning compressor working. Selecting VENT and the AUTO button at the same time allows the system to control automatically without the use of the RECIRC mode. To turn off the VENT selection, push the VENT button again. If you select VENT while in FRONT defrost, the VENT light will flash three times to let you know this is not allowed. This is to prevent fogging. RECIRC: When RECIRC is selected, the system will limit the amount of outside air entering your vehicle. This is helpful when you are trying to cool the interior of the vehicle quickly or limit the amount of outside air entering your vehicle. RECIRC and AUTO may be selected at the same time. The system will remain in RECIRC until the ignition is turned off, then the system will return back to the previously selected mode. Deselecting the RECIRC button will also turn off the RECIRC function. RECIRC can be selected in all manual airflow modes except FRONT defrost and VENT. If you select RECIRC while in FRONT defrost, the RECIRC light will flash three times to let you know this is not allowed. This is to prevent fogging. 3-6
