Press to turn the rear window defogger on or off.

The rear window defogger stays on for about 15 minutes, before turning off if the vehicle is moving at a slower speed. At higher speeds, the rear window defogger may stay on continuously. With each additional press, the defogger runs for about 10 minutes. The defogger can also be turned off by turning off the engine.

The heated outside rearview mirrors turn on when the rear window defogger button is on and helps to clear fog or frost from the surface of the mirrors. See Heated Mirrors.

Notice: 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.

In cold weather the windshield defroster and/or rear window defogger automatically turn on.

If the vehicle has heated seats, they will also turn on.

When the ignition is turned to ON/RUN, the climate control system returns to the settings used before the vehicle was last turned off.

The heated seats will turn off, if equipped.
