2007 CHEVROLET TAHOE heating

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent type.
Make sure the cover is on tightly, so water will
not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from
outside of the vehicle. It may also start up the
vehicle’s heating or air conditioning systems and
rear window defogger. Normal operation of the
system will return after the key is turned to the RUN
position.
During a remote start, if your vehicle has an
automatic climate control system, the climate
control system will default to a heating mode during
colder outside temperatures and a cooling mode
during warmer outside temperatures. If your vehicle
does not have an automatic climate control system,
during remote start, the climate control system will
turn on at the setting the vehicle was set to when
the vehicle was last turned off.During a remote start, if your vehicle has an
automatic climate control system and heated
seats, the heated seats will turn on during colder
outside temperatures and will shut off when
the key is turned to RUN. If your vehicle does not
have an automatic climate control system,
during remote start, you will need to manually turn
the heated seats on and off. SeeHeated Seats
on page 12for additional information.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have the
vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The RKE transmitter with the remote start button,
provides an increased range of operation. However,
the range may be less while the vehicle is running.
As a result, you may need to be closer to your
vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 114for
additional information.

If the passenger’s side power door lock switch is
pressed when the front passenger’s door is
open and the key is in the ignition, all of the doors
will lock and then the front passenger’s door
will unlock.
Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It
can cause unconsciousness and even
death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 227orDual Automatic Climate
Control System on page 231.
If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeeEngine Exhaust on page 160.
If your vehicle has a power liftgate, seePower
Liftgate on page 127.

It is not recommended that you drive with the
liftgate open, however, if you must drive with the
liftgate open, the power liftgate should be switched
to manual liftgate operation — the overhead
console switch set to the “Disable” position.
Both the liftglass and liftgate have an electric latch.
If the battery is disconnected or has low voltage,
the liftglass and liftgate will not open. The
liftglass and liftgate will resume operation when
the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.

Ashtray(s) and Cigarette Lighter
The front ashtray is located near the center of the
instrument panel or on the front console, if
equipped. Pull on the ashtray door to open it.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
To remove the front ashtray pull the ashtray up.
To use the cigarette lighter, push it in all the way,
and let go. When it’s ready, it will pop back out
by itself.
Notice:Holding a cigarette lighter in while it
is heating does not let the lighter back
away from the heating element when it is hot.
Damage from overheating can occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in while it
is heating.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, defrost, defog and ventilation of
your vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise
to direct the airow inside of your vehicle.
227

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
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.
AUX (Auxiliary):Pressing this button will turn the
rear heating and air conditioning on. SeeRear
Air Conditioning and Heating System on page 239
orRear Air Conditioning and Heating System
and Electronic Climate Controls on page 240for
more information.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the temperature
on the driver’s side or the passenger side of the
vehicle for the dual zone system.#(Air Conditioning):Press this button on the
left knob to turn the air conditioning system on or
off. When A/C is pressed, an indicator light will
come on to let you know that the air conditioning
has been activated.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog on the inside of the windows is a result of
high humidity (moisture) condensing on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to clear fog or frost from your
windshield. Turn the right knob clockwise to select
the defog or defrost mode.
229

Dual Automatic Climate Control
System
With this system, you can control the heating,
cooling, and ventilation in your vehicle. Your
vehicle also has a ow-through ventilation system
described later in this section.
You can select different climate control settings for
the driver and passengers.
Driver’s Side Temperature Control
The driver’s side temperature buttons are used to
adjust the temperature of the air coming through
the system on the driver’s side. The temperature
can be adjusted even if the system is turned
off. This is possible since outside air will always
ow through the system as the vehicle is moving
forward unless it is set to recirculation mode.
See “Recirculation” later in this section.
Press the + or−buttons to increase or decrease
the cabin temperature. The driver side
temperature display will show the temperature
setting decreasing or increasing.
231

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
Use the air outlets located in the center and on
the side of your instrument panel to direct
the airow.
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.
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
your window.
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, may
affect the performance of the heating and air
conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
