Rear Window Defogger
(Rear Window Defogger):
Press to turn the rear window defogger on or off.
The rear window defogger turns off automatically after about 10 minutes. If turned on again it runs for about five minutes before turning off. The defogger can also be turned off by turning the ignition to ACC/ACCESSORY or LOCK/OFF.
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°C (40°F) 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.
For vehicles with heated outside rearview mirrors, they turn on when the rear window defogger button is on and help to clear fog or frost from the surface of the mirror. 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. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs would not be
covered by your warranty.
(Heated Steering Wheel): For
vehicles with this feature, press to
turn on or off. See Heated Steering
Wheel.
Remote Start Climate Control Operation (If Equipped): When the vehicle is started remotely, the climate control system will use the last setting before the vehicle shut off. If automatic operation was set, the fan speed will adjust to maximize heating or cooling.
If manual operation was set, the fan speed will be limited to the last setting. In extreme temperatures, the system may not be able to heat or cool the vehicle to the preset temperature during the remote start run time.
The rear window defogger turns on if it is cold outside.
