Passenger Temperature Control If your vehicle has this feature, then the driver and the front-seat passenger can select separate temperature settings. This feature allows the passenger to select a temperature that is 5° F (3° C) warmer or cooler than the driver's selected temperature. The control is located on the passenger's door armrest. Outlet Adjustment Use the levers located in the middle of the front outlets to change the direction of the airflow. Press the red button for a warmer temperature or the blue button for a cooler temperature. Press the OFF button on the main system once to turn off the passenger's temperature control. Press the OFF button twice to turn off the entire climate control system. In vehicles equipped with rear seat outlets, you can adjust the direction of the airflow using the lever in the center of each outlet. Use the thumbwheel located between the outlets to turn them on and off. 3-30
