Rear Window Defogger - Cadillac 2006 CTS 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
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.

(Mode): Press this button until defog appears
on the display.
-
(Defog): This mode directs the air between the
windshield, floor outlets and side windows. When this
mode is selected, 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 in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the thumbwheel
on the outboard outlets to the side window defog position.
See Outlet Adjustment on page 3-28 for more
information.
0
(Defrost): Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. See Outlet Adjustment on page 3-28
for more information. 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.
The rear window defogger will only work when the
ignition is in ON.
