Chevrolet 2009 Avalanche Automobile User Manual


 
9 (Fan Control): Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turn the
knob all the way counterclockwise to turn the front
system off.
Air Delivery Mode Control: Turn clockwise or
counterclockwise to change the direction of the airflow
inside the vehicle. The knob can be positioned between
two modes, for a combination of those modes.
To change the current mode, select one of the following:
H (Vent): Air is directed to the instrument panel
outlets.
) (Bi-Level): Air is divided between the instrument
panel and floor outlets. Some air is directed towards the
windshield and side window outlets. Cooler air is directed
to the upper outlets and warmer air to the floor outlets.
6 (Floor): Air is directed to the floor outlets, with some
of the air directed to the windshield, side window, and
second row floor outlets. In this mode, the system
automatically selects outside air. Recirculation cannot
be selected when in Floor Mode.
- (Defog): The defog mode is used to clear the
windows of fog or moisture. Air is directed to the
windshield, floor outlets, and side window vents. In this
mode, the system turns off recirculation and runs
the air conditioning compressor unless the outside
temperature is close to freezing. The recirculation mode
cannot be selected while in the defog mode.
0 (Defrost): The defrost mode is used to remove fog
or frost from the windshield more quickly. Air is
directed to the windshield and side window vents, with
some directed to the floor vents. In this mode, the
system automatically forces outside air into the vehicle.
The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor runs
automatically in this setting, unless the outside
temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
# (Air Conditioning): Press this button to turn the
air conditioning system on or off. An indicator light
comes on to show that the air conditioning is on. The air
conditioning can be selected in any mode as long as
the fan control is on.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This is
normal.
