If driving below 50 mph (80 km/h), the rear window defogger will turn 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.

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.
