Rear Window Defogger - Cadillac 2010 DTS Owner's Manual

Rear Window Defogger

The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<
(Rear Defogger): Press to turn the rear window
defogger on or off. Be sure to clear as much snow
from the rear window as possible. The rear window
defogger will turn off approximately 20 minutes after the
button is pressed if the vehicle is moving at slower
vehicle speeds. At higher vehicle speeds, the rear
defogger may stay on continuously. Each additional
press will run the defogger for approximately 10 minutes.
The heated outside rearview mirrors will turn on to
help clear fog or frost from the surface of the mirror
when the rear window defogger is on.
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.
