Passenger Temperature Control If your vehicle has the optional separate passenger's 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. 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. 3-29
