Rear Window Defogger - Cadillac 2008 SRX Owner's Manual

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system
is used properly. There are two modes to clear fog
from the windshield.
W
(Floor/Defog): Use this mode to clear the windows
of fog and warm the passengers. The system turns off
recirculation and runs the air conditioning compressor
unless the outside temperature is at or below freezing.
If recirculation mode is selected while using the defog
mode, the system recirculates air initially but returns to
the fresh air mode after 10 minutes.
0
(Defrost): Use this mode to remove fog or frost
from the windshield more quickly. When selected, the
system turns off recirculation and runs the air conditioning
compressor, unless the outside temperature is at or
below freezing.
Do not drive the vehicle until all the windows are clear.

Rear Window Defogger

The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<
(Rear Defogger): Press the center of the right
control 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 turns off
about 20 minutes after the button is first pressed if the
vehicle is moving at slower speeds. At higher vehicle
speeds, the rear defogger can stay on continuously.
Each additional press runs the defogger for about
10 minutes.
The heated outside rearview mirrors also heat 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.
