2010 CHEVROLET TAHOE heating

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 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.

#(Air Conditioning):Press to turn the air
conditioning (A/C) compressor on and off. An indicator
light comes on to show that the air conditioning is on.
If this button is pressed when the air conditioning
compressor is unavailable, the indicator flashes
three times and then turns off. If the air conditioning
is on and the outside temperature drops below a
temperature which is too cool for air conditioning to
be effective, the air conditioning light turns off to show
that the air conditioning mode has been canceled.
On hot days, open the windows long enough to let hot
inside air escape. 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.
@(Recirculation): Press to turn the recirculation
mode on or off. An indicator light comes on to show that
the 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, defog,
or defrost modes. If recirculation is selected with one of
those modes, the indicator light flashes three times and
then turns off. The air conditioning compressor also
comes 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 ignition.
REAR:
For vehicles with the rear heat and air
conditioning controls. Press to turn the rear climate
control system on or off. See Rear Air Conditioning and

Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow.
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 the windows.
.When you enter a vehicle in cold weather, press
the fan up button to the maximum fan level before
driving. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging
the inside of the window.
.Keep the air path under the front seats clear of
objects. This helps air to circulate throughout the
vehicle.
.Adding outside equipment to the front of the
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of the vehicle.

Engine Coolant Temperature Gauge
United StatesCanada
This gauge shows the engine coolant temperature.
It also provides an indicator of how hard the vehicle is
working. During a majority of the operation, the gauge
reads 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark. If the
gauge reaches the 260°F (125°C) mark, it indicates that
the cooling system is working beyond its capacity.
See
Engine Overheating on page 6‑36.
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
