At speeds above 30 mph (48 km/h), the defogger will operate continuously until you press the REAR button again. After 10 minutes of driving below 30 mph (48 km/h), the defogger will turn off automatically. If you need additional warming time, push the button again. The system will then operate for five minutes before going off by itself. If your vehicle has heated outside rearview mirrors, the mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defogger button is pressed. Notice: Using a razor blade or sharp object to clear the inside rear window may damage the rear window defogger. Repairs would not be covered by your warranty. Do not clear the inside of the rear window with sharp objects. The lever for this feature is located on the right side of the instrument panel. Slide the lever toward WARM for warmer air or toward COOL for cooler air. Press OFF on the main climate control system once to turn off the passenger's temperature control. When this lever is moved, the current inside temperature will appear on the display for a few seconds, then the outside temperature will appear. Passenger Temperature Control If your vehicle has the passenger temperature control, then the driver and the right front passenger can select separate temperature settings. This feature allows the front passenger to select a temperature that is 5° F (3° C) warmer or cooler than the driver's selected temperature. 3-29
