To change the current mode, select one of the following: h (Recirculation): Y (Vent): This mode directs air to the instrument panel outlets. \ (Bi-Level): This mode directs approximately half of the air to the instrument panel outlets, and then directs most of the remaining air to the floor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the floor outlets. This mode directs most of the air to the floor outlets with some air directed to the outboard outlets (for the side windows), and a little air directed to the windshield. The mode switch can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section. 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 to help heat or cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on or off. The air-conditioning compressor also comes on. After manually selecting recirculation, the auto button must be pressed to enable the system to select the optimum air delivery setting for the vehicle. Recirculation is not available in the defog or defrost mode and will automatically turn off after 10 minutes when defog is selected. Using recirculation for long periods of time may cause the air inside your vehicle to become too dry or stuffy. To prevent this from happening, after the air in your vehicle has cooled, turn the recirculation mode off or press the auto button. [ (Floor): yAz (Fan): Press this switch to increase or decrease the fan speed. Pressing this switch cancels automatic operation and places the system in manual mode. Press AUTO to return to automatic operation. 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 3-29 and Scheduled Maintenance on page 6-4. QPWRR (Power/Driver's Temperature): Press the PWR button located on the driver's side of the climate control panel to turn the entire climate control system on or off. Press the up or down arrow on the switch to increase or decrease the temperature inside your vehicle. 3-25
