Defogging and Defrosting Use either the defog or front defrost to clear fog or frost from the windshield. If driving below 50 mph (80 km/h), the rear window defogger turns off about 15 minutes after the button is pressed. If turned on again, the defogger will only run for about seven and one-half minutes before turning off. If your vehicle's speed is maintained above 50 mph (80 km/h), the rear window defogger remains on once the button is pressed. If your vehicle has the remote start feature, the rear defogger automatically turns on if it is cold outside, but the indicator light does not come on. When the vehicle transitions out of remote start mode the rear defogger turns off. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. - (Defog): Turn the mode knob to this position to clear the windows of fog or moisture. This setting delivers air to the floor and windshield outlets.
