Saturn 2010 AURA - Manual (Page 174)

h (Recirculation): Press to turn the recirculation
mode on. An indicator light above the button comes on
to show it is on. This mode recirculates and helps to
quickly cool the air inside the vehicle. It can be used to
help prevent outside air and odors from entering the
vehicle. The recirculation indicator light blinks three
times if you try to use recirculation in a mode in which it
cannot function.
Pressing this button cancels the auto recirculation
feature. Each time the vehicle is started, the system
reverts to the auto recirculation function.
The recirculation mode cannot be used with the floor,
defrost, or defog modes. If recirculation is selected
in these modes, the indicator flashes three times and
turns off to indicate that this is not allowed. This is
to prevent window fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on. Allow the air conditioning to run
automatically to help dehumidify the air.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
< (Rear): Press to turn the rear window defogger on
or off. An indicator light comes on to show that the
rear window defogger is on.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If additional warming time is needed, press the
button again.
If the vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
For vehicles with heated outside mirrors, the surface of
the outside mirrors will also heat when the rear
window defogger is activated. See Outside Power
Mirrors on page 3-34.
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.
