Chevrolet 2009 Avalanche Automobile User Manual


 
: (Outside Air): Press to turn the outside air mode
on. An indicator light comes on to show that outside
air is on. Air from outside the vehicle is circulated
throughout the vehicle. The outside air mode can be
used with all modes, but it cannot be used with
the recirculation mode. Pressing this button again will
cancel the recirculation mode.
? (Recirculation): Press to turn the recirculation
mode on or off. An indicator light comes on to show that
recirculation 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 mode cannot be used with floor,
defrost, or defogging modes. If recirculation is selected
while in one of those modes, the indicator flashes
three times and turns off. The air conditioning
compressor will also come on when this mode is
activated. While in recirculation mode the windows may
fog when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode and increase
the fan speed. The recirculation mode can also be
turned off by turning off the engine.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
< (Rear Window Defogger): Press this button on
the right knob to turn the rear window defogger on or off.
The system automatically turns off several minutes
after it has been activated. The defogger can also be
turned off by turning off the engine. Do not drive
the vehicle until all the windows are clear.
For vehicles with heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
