Do not attach a temporary vehicle license across the defogger grid on the rear window. NOTICE: Don't use a razor blade or something else sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn't be covered by your warranty. To send conditioned air to the rear of the vehicle, press the A/C button on the main climate controls. If you do not select A/C, air directed to the rear of the vehicle will be cabin temperature. Rear Fan Control This option comes with the rear climate controls. Keep the area around the base of the center instrument panel console and the area between and under the front seats free of objects that would obstruct airflow to the rear of the vehicle. The rear fan control is located below the climate control system, in the switchbank. Rear Climate Control (Vehicles without the Entertainment System) (Option) If you have the optional rear climate control, the rear seat passengers can control the temperature and the amount of air directed to the rear of the vehicle. You can also adjust the amount of air directed to the rear of the vehicle using the front fan knob. When it's cold outside, set the main climate control mode knob to floor, defog or defrost to send air to the rear of the vehicle through the floor ducts. Set the main climate control mode knob to vent or bi-level to send air to the rear of the vehicle through the headliner outlets. 3-6
