2007 HUMMER H2 window

Pressing this button also cancels the auto
recirculation feature. To resume the auto
recirculation function, press the AUTO button.
Each time the vehicle is started, the system will
revert to the auto recirculation function.
If you select recirculation while in defrost, defog or
oor, the light in the button will ash and then go out
to let you know that this is not allowed. This is
normal and helps to prevent fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time
may cause fogging of the vehicle’s windows. To
clear the fog, select either defog or front defrost.
You may also notice that the A/C compressor will
run while in recirculation mode. This is normal and
helps to prevent fogging.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still enter the
vehicle, and will be directed to the oor. This
direction can be changed by pressing the mode
button. The temperature can also be adjusted using
either temperature knob. Press the up or down
arrows on the fan switch, the defrost button, the
AUTO button, or the air conditioning button to turn
the system on when it is off.
Display
If you press the MODE button to select an air
delivery mode, the display will change to show you
the selected air delivery mode. After ten seconds,
the display will change to show the driver
temperature setting and the selected mode.
If you press the up or down arrows on the fan
switch, the display will change to show the
selected fan speed. After ten seconds, the display
will change to show the driver temperature
setting and the selected mode.
Whenever you press AUTO, the display will
change to show the following:
the current driver’s set temperature and an
arrow for ve seconds,
the current passenger’s set temperature
setting and an arrow for ve seconds and
the automatic air delivery mode and fan speed.
If the driver’s and passenger’s temperature settings
are the same when AUTO is pressed, the
temperature setting and both arrows will be
displayed for ve seconds along with the automatic
air delivery mode and fan speed. After the
ve second update, the display will change to show
the temperature setting, both arrows and AUTO.

Air Conditioning
#
(Air Conditioning):Press this button to turn
the air conditioning (A/C) compressor on and
off. The snowake symbol will appear on
the display when the A/C is on.
Pressing this button when the outside temperature
is too cool for air conditioning to be effective will
make the snowake symbol ash three times
and then turn off to let you know that the air
conditioning mode is not available. 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 snowake
symbol will turn off to let you know that the air
conditioning mode has been canceled.
When air conditioning is selected or in AUTO
mode, the system will run the air conditioning
automatically to cool and dehumidify the air
entering the vehicle. If you select A/C off while in
front defrost, defog or recirculation, the A/C
snowake symbol will turn off, but the A/C
compressor will still run to help prevent fogging.On hot days, open the windows long enough to let
hot inside air escape. This reduces the time it takes
for your vehicle to cool down. Then keep your
windows closed for the air conditioner to work
its best.
On cool, but sunny days while using manual
operation of the automatic system, use bi-level to
deliver warm air to the oor and cooler air to
the instrument panel outlets. To warm or cool the
air delivered, turn the temperature knob to the
desired setting.
In AUTO mode the system will cool and dehumidify
the air inside the vehicle. Also while in AUTO
mode, the system will maximize its performance
by using recirculation as necessary.
Heating
On cold days when using manual operation of the
automatic system, choose oor mode to deliver
air to the oor outlets. To warm or cool the
air delivered, turn the temperature knob to the
desired setting.
If you want to use the automatic mode, press
AUTO and adjust the temperature by turning the
temperature knob.
The heater works best if you keep the windows
closed while using it.

Defogging and Defrosting
You can use either defog or front defrost to clear
fog or frost from your windshield. Use the
defog mode to clear the windows of fog or
moisture. Use the front defrost button to defrost
the front windshield.
-(Defog):Use this setting to clear the windows
of fog or moisture. Press the mode button to
select this setting. This setting will deliver air to
the oor and windshield outlets.
0(Front Defrost):Press the front defrost button
to defrost the windshield. The system will
automatically control the fan speed if you select
defrost from AUTO mode. If the outside
temperature is 40°F (4°C) or warmer, your air
conditioning compressor will automatically run to
help dehumidify the air and dry the windshield.
Rear Window Defogger
If your vehicle has this feature, the lines you see
on the rear window warm the glass. The rear
window defogger uses a warming grid to remove
fog from the rear window.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light in the
button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off about
10 minutes after the button is pressed. If you need
additional warming time, press the button again.
If your vehicle is equipped with heated mirrors this
button will activate them.
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 that allow you to
adjust the direction and amount of airow inside
the vehicle. Push the knob in the center of
the outlet up, down, left or right to move the outlet
in the direction you would like. Turn the knob in
the center of the outlet so the louvers open
or close to increase or decrease 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.
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.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair orreplacement. Paying attention to your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.
Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let you
know when there is a problem with your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous. So
please get to know your warning lights and
gages. They are a big help.
Your vehicle also has a Driver Information
Center (DIC) that works along with warning lights
and gages. SeeDIC Warnings and Messages
on page 226.

Headphones
Wireless Headphones
The RSE system might include two sets of
wireless headphones. Each headphone has an
L marked on the left-side, for the left ear and an
R marked on the right-side, for the right ear. The
L and R marks are to show how the headphones
should be worn.
OFF/ON (Power):The wireless headphones have
an OFF/ON power switch located on the
earpiece. To use the headphones, turn the switch
to ON. An indicator light on the earpiece of the
headphones illuminates. If the light does not
illuminate, the batteries might need to be replaced.
See “Battery Replacement” later in this section.
Switch the headphones to OFF when not in use.
The headphones shut off automatically to save the
battery power if the RSE system is shut off or if
the headphones are out of range of the transmitter
window for more than three minutes. The
transmitter window is located on the bottom edge
of the monitor. If you move too far forward or
step out of the vehicle, the headphones could lose
the audio signal.Channel Selector:The wireless headphones
have a channel selector switch located on the right
earpiece. The channel selector switches between
Channel A and Channel B. Since each monitor
can function as two independent sources through
auxiliary input, it is necessary to transmit audio
signals on separate channels. The driver’s
side monitor is designated as Channel A, and the
passenger’s side as Channel B. The Headphone
channel selector switch must be set to the
correct channel according to the monitor being
viewed. When the head restraint monitor is initially
turned on, the message, “To listen to this
monitor tune your headphones to channel A
(or B)” displays for ve seconds then disappears.
VOL
0(Volume):To adjust the volume
on the wireless headphones, use the volume
control.
Notice:Do not store the headphones in heat
or direct sunlight. This could damage the
headphones and repairs will not be covered by
your warranty. Keep the headphones stored
in a cool, dry place.

Infrared Remote Sensor:The infrared remote
sensor receives light signals from the system’s
remote control. The infrared remote sensor
is located on the upper right side of the monitor.
This sensor works as a line-of-sight signal as
the transmitted signals are received. In order for
the sensor to work properly, it must remain
unobstructed at all times.
Infrared LED (Light Emitting Diode) Window:
The infrared LED window sends audio signals
to the wireless headphones. The infrared
LED window is located on the lower front
monitor, surrounding the monitor’s faceplate
buttons. In order for the infrared LED window
to work properly, it must remain unobstructed
at all times.
X(Wired Headphone Jack):This type of
headphone jack is used with universal wired
headphones (not included). The wired headphone
volume is adjusted using the up and down
arrow buttons. See “Wired Headphones” earlier in
this section.AUX (Auxiliary):The auxiliary input jack is an
AV 3 input jack. The auxiliary input jack is located
on the left lower side of the monitor, next to the
wired headphone jack. This auxiliary input jack lets
you view auxiliary sources such as portable
DVD units, game stations, video cameras, etc., on
each individual monitor. The sources connected
to these inputs cannot be shared between
the monitors.
Press the SOURCE soft key button on either
monitor, or the SOURCE button on the system’s
remote control to select the desired auxiliary
source. See “SOURCE” under Video Screens
earlier in this section.

Cleaning the Video Screens
The video display screens are made of a specially
coated glass and can be scratched or damaged
by abrasive products, solvents, or ammonia-based
window cleaners. Occasionally take a soft,
lint-free, cotton cloth that has been slightly
dampened with warm water and wrung out
completely. Dry the screens by wiping with a clean
dry cotton cloth.

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion. After
driving for any distance at higher speeds, you may
tend to think you are going slower than you
actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too many
miles that rst part of the journey. Wear comfortable
clothing and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.Of course, you will nd experienced and able
service experts in GM dealerships all across
North America. They will be ready and willing to
help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
