Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. Outlet Adjustment Use the louvers on the air outlets to change the direction of the airflow. < REAR: Press this button to turn the rear window defogger on or off. An indicator light above the button will come on to let you know that the rear window defogger is activated. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off approximately 10 minutes after the button is pressed. If turned on again, the defogger will only run for approximately five minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Notice: Don't use anything 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. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. Operation Tips • Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the flow of air into your vehicle. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. • When an objectionable odor outside the vehicle is encountered, use the MAX mode, with the temperature knob at a comfortable setting to prevent the odor from entering the vehicle through the ventilation system. This can be helpful when driving through a long tunnel with poor ventilation. However, extended usage of this mode in cold or cool weather can cause window fogging. 3-21
