1 (Defrost): This mode directs most of the air to the windshield and the side window outlets, with only a little air directed to the floor outlets. The air conditioning compressor will run automatically to dehumidify the air to prevent window fogging. The recirculation mode cannot be selected while in defrost mode. Do not drive the vehicle until all the windows are clear. < (Rear): Press this button to turn the rear window defogger on or off. An indicator light in the button will come on to let you know that the rear window defogger is activated. This button will also activate the heated mirrors, if the vehicle has them. The rear window defogger will automatically turn off several minutes after the button is pressed. Pressing the button while the defogger is running can also turn off the defogger. Rear Window Defogger If your vehicle has this feature, the rear window defogger uses a warming grid to remove fog from the rear window. If your vehicle has a sliding rear window, you will not have a rear window defogger. W (Mirror): If your vehicle does not have a rear defogger and has heated mirrors, your vehicle will have this button to activate the heated mirrors. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. 232
