Climate Controls 8-7 # (Air Conditioning): Press to turn the air conditioning (A/C) compressor on and off. An indicator light comes on to show that the air conditioning is on. If this button is pressed when the air conditioning compressor is unavailable, the indicator flashes three times and then turns off. If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the air conditioning light turns off to show that the air conditioning mode has been canceled. On hot days, open the windows long enough to let hot inside air escape. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so a small amount of water might drip under the vehicle while idling or after turning off the engine. This is normal. Press to turn the recirculation mode on or off. An indicator light comes on to show that the recirculation is on. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to help prevent outside air and odors from entering the vehicle. The recirculation mode cannot be used with floor, defog, or defrost modes. If recirculation is selected with one of those modes, the indicator light flashes three times and then turns off. The air conditioning compressor also comes on when this mode is activated. While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. The recirculation mode can also be turned off by turning off the ignition. PASS: Press to set the passenger temperature setting to match the driver temperature setting. The PASS indicator will turn off. When the passenger temperature setting is set different than the driver setting, the indicator on the PASS button illuminates and both the driver side and passenger side temperature displays are shown. REAR: For vehicles with the rear heat and air conditioning controls. Press to turn the rear climate control system on or off. See Rear Climate Control System (Rear Climate Control Only) on page 8‑9 or Rear Climate Control System (with Rear Seat Audio) on page 8‑10. @ (Recirculation): Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window.
