steering HUMMER H2 2007 Owners Manual

There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 207for more information.Where Are the Airbags?
The driver’s airbag is in the middle of the
steering wheel.
79

The right front passenger’s airbag is in the
instrument panel on the passenger’s side.
{CAUTION:
If something is between an occupant and
an airbag, the bag might not inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating airbag must
be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.
80

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. Ination is determined by
what the vehicle hits, the angle of the impact, and
how quickly the vehicle slows down.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving on page 317for more tips
on off-road driving.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. The sensing system triggers a release
of gas from the inator, which inates the
airbag. The inator, airbag, and related hardware
are all part of the airbag modules inside the
steering wheel and in the instrument panel in front
of the right front passenger.
How Does an Airbag Restrain?
In moderate to severe frontal or near-frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. The
airbag supplements the protection provided by
safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually.
But airbags would not help you in many types of
collisions, including rollovers, rear impacts,
and many side impacts, primarily because an
occupant’s motion is not toward those airbags.
Airbags should never be regarded as anything
more than a supplement to safety belts, and then
only in moderate to severe frontal or near-frontal
collisions.
82

What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Some components of the airbag
module — the steering wheel hub for the driver’s
airbag or the instrument panel for the right
front passenger’s bag — may be hot for a short
time. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.
There may be some smoke and dust coming from
the vents in the deated airbags. Airbag ination
does not prevent the driver from seeing out of the
windshield or being able to steer the vehicle,
nor does it prevent people from leaving the vehicle.
{CAUTION:
When an airbag inates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the vehicle
after an airbag inates, then get fresh air
by opening a window or a door. If you
experience breathing problems following
an airbag deployment, you should seek
medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on,
and turn the hazard warning ashers on when the
airbags inate. You can lock the doors again,
turn the interior lamps off, and turn the hazard
warning ashers off by using the controls for those
features.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
of the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of theCustomer Satisfaction
Procedure on page 536.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
the instrument panel, or airbag wiring can
affect the operation of the airbag system. If
you have questions, call Customer Assistance.
The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure
on page 536.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. SeeCare of Safety Belts on page 495
for more information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
the airbag may not work properly. You may
have to replace the airbag module in the
steering wheel or both the airbag module and
the instrument panel for the right front
passenger’s airbag. Do not open or break the
airbag coverings.

Global Window Feature
The global window up
and express-down
buttons are located on
the driver’s door.
This feature allows all side windows and midgate
window, if equipped, to be opened or closed
at the same time.
q(Window Express-Down):Press the
express-down button to lower all side windows
and midgate window, if equipped, without stopping.
Express-down will operate while the ignition is in
RUN or ACCESSORY, or while Retained
Accessory Power (RAP) is active. SeeRetained
Accessory Power (RAP) on page 121.If the key is out of the ignition, express-down will
only activate while the driver’s door is open
and the content theft-deterrent system is disabled.
To stop the express-down, press the up button.
Pressing the global express-down button also
activates the power midgate latch release buttons,
if equipped. See “Lowering the Midgate” under
Midgate
®(SUT) on page 105.
n(Window Up):Press the up button to raise all
windows. The midgate window, if equipped,
will express-up while the side windows will go up
a small amount at a time. Press and hold the
up button to raise the four side windows all the
way. The up button operates while the ignition is in
RUN or ACCESSORY, or while RAP is active.
Midgate Window
If your vehicle has a midgate, the switch to
operate the window is located on the instrument
panel to the left of the steering wheel. See
Instrument Panel Overview on page 174.

Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Lengthy operation of features such as the radio in
the accessory ignition position and the RUN
position may drain the battery and prevent your
vehicle from starting. Do not operate your vehicle
in the accessory ignition position for a long
period of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.
120

FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using
your brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transmission will not shift into rst gear until the
vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be covered by
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
On cold days, approximately 32°F (0°C) or colder,
your transmission is designed to shift differently
until the engine reaches normal operating
temperature. This is intended to improve heater
performance.Tow/Haul Mode
Your vehicle is equipped
with a tow/haul mode.
The button is located on
the instrument panel
to the right of the
steering wheel.
You can use this feature to assist when towing or
hauling a heavy load. See “Tow/Haul Mode”
underTowing a Trailer on page 374for more
information.

OnStar®Steering Wheel Controls
Your vehicle may have a Talk/Mute button that
can be used to interact with OnStar®Hands-Free
Calling. SeeAudio Steering Wheel Controls on
page 296for more information.
On some vehicles, you may have to hold the
button for a few seconds and give the command
“ONSTAR” in order to activate the OnStar
®
Hands-Free Calling feature.
On some vehicles, the mute button can be used to
dial numbers into voicemail systems, or to dial
phone extensions. See the OnStar
®Owner’s
Guide for more information.
How OnStar®Service Works
In order to provide you with OnStar®services,
your vehicle’s OnStar®system has the capability
of recording and transmitting vehicle information.
This information is automatically sent to an
OnStar
®Call Center at the time of an OnStar®
button press, Emergency button press or if
your airbags or AACN system deploys. The vehicle
information usually includes your GPS location
and, in the event of a crash, additional information
regarding the accident that your vehicle has
been involved in (e.g. the direction from which
your vehicle was hit). When you use the Virtual
Advisor feature of OnStar
®Hands-Free Calling,
your vehicle also sends OnStar®your GPS
location so that we can provide you with
location-based services.
