2007 CHEVROLET AVALANCHE wheel

The air conditioning compressor will be on unless
the outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease
the fan speed. Turn the knob all the way
counterclockwise to turn the front system off.
:(Outside Air):Press this button to turn
on the outside air mode. When this mode
is selected, air from outside the vehicle will
circulate throughout your vehicle. An indicator
light on the button will come on to let you know
that it is activated. 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 this button to turn
on the recirculation mode. When the button
is pressed, an indicator light will come on.This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air
and prevent odors from entering your vehicle.
Recirculation may also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
light will ash three times and turn 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.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver’s side or the passenger
side to the vehicle for the dual zone system.

Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the
solar radiation. Do not cover the solar sensor
or the system will not work properly.There is also an interior temperature sensor
located next to the steering wheel that measures
the temperature of the air inside your vehicle.
There is also an exterior temperature sensor
located behind the front grille. This sensor reads
the outside air temperature and helps maintain
the temperature inside the vehicle. Any cover
on the front of the vehicle could cause a
false reading in the displayed temperature.
236

Rear Window Defogger
The rear window defogger uses a warming grid
to remove fog from the rear window.
<(Rear Window Defogger):Press this button
to turn on the rear window defogger. It will
automatically turn off several minutes after it
has been activated. The defogger can also be
turned off by pressing the button again or by
turning off the engine. Do not drive the vehicle
until all the windows are clear.
If your vehicle has 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 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.
Outlet Adjustment
Your vehicle has air outlets located in the center
and on the side of your instrument panel that
allow you to adjust the direction and amount of
airow inside the vehicle. Move the louvers up or
down. Use the thumbwheel next to or underneath
the outlet to close the louvers. For the most
efficient airow and temperature control, keep
the outlet in the fully opened position.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction, such as
leaves. The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, etc.,
may affect the performance of the heating
and air conditioning system. Check with
your dealer before adding equipment to the
outside of your vehicle.

If the warning light does not come on then, have
it xed so it will be ready to warn you if there
is a problem. If it stays on, or comes on when
you are driving, there may be a problem with your
StabiliTrak
®system and your vehicle may need
service. When this warning light is on, the system
is off and will not limit wheel spin. Adjust your
driving accordingly.
This light will also ash when the StabiliTrak
®
system is active.
If the StabiliTrak
®system warning light comes on
and stays on for an extended period of time when
the system is turned on, your vehicle needs service.
SeeStabiliTrak
®System on page 359for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your
vehicle is working. During a majority of the
operation, the gage will read 210°F (100°C) or
less. If you are pulling a load or going up hills,
it is normal for the temperature to uctuate
and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond
its capacity.
