The rear window defogger only works when the engine is running.

It turns off when the ignition is turned off or in ACC/ACCESSORY.

The rear window defogger can be set to automatic operation. See "Climate and Air Quality" under Vehicle Personalization.

When Auto Rear Defog is selected, the rear window defogger turns on automatically when the interior temperature is cold and the outside temperature is about 4 ВєC (40 ВєF) and below. The auto rear defogger turns off automatically after about 10 minutes, or after five minutes if the outside temperature is not as cold.

The upper gridlines on the rear window are antenna lines and are not intended to heat when the defogger is activated.

The heated outside mirrors turn on when the rear window defogger control is on and help to clear fog or frost from the surface of the mirror.

Caution: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect the radio's ability to pick up stations clearly. The repairs would not be covered by the vehicle warranty.
