HUMMER H2 2006 Repair Manual

Never put a rear-facing child restraint in the right front
passenger’s seat unless the airbag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. Be sure to turn
off the airbag before using a rear-facing child
restraint in the right front seat position.
Even though the airbag off switch is designed to
turn off the passenger’s airbag, no system is fail
safe, and no one can guarantee that an airbag
will not deploy under some unusual
circumstance, even though it is turned off.
General Motors recommends that rear-facing
child restraints be secured in the rear seat, even
if the airbag is off.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group sit in
the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced. See
Airbag Off Switch on page 1-65andAirbag
Readiness Light on page 3-32for more on this,
including important safety information.

You will be using a lap-shoulder belt to secure the child
restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
1. Your vehicle has a right front passenger’s airbag.
SeeAirbag Off Switch on page 1-65. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the restraint in
this seat. SeePower Seats on page 1-2.Ifyou
need to use a rear-facing child restraint in this seat,
make sure the airbag is off once the child restraint
has been installed.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-56

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder
belt back into the retractor. If you are using a
forward-facing child restraint, you may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
1-57

To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
If you had turned the airbag off with the switch,
remember to be sure to use the airbag off switch to turn
on the right front passenger’s airbag when you remove
the child restraint from the vehicle unless the person
who will be sitting there is a member of the passenger
airbag risk group. SeeAirbag Off Switch on page 1-65.
{CAUTION:
If the right front passenger’s airbag is turned
off for a person who is not in a risk group
identied by the national government, that
person will not have the extra protection of an
CAUTION: (Continued)
CAUTION: (Continued)
airbag. In a crash, the airbag will not be able to
inate and help protect the person sitting
there. Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group. SeeAirbag Off Switch on page 1-65for
more on this, including important safety
information.
Airbag System
Your vehicle has an airbag for the driver and an airbag
for the right front passenger.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating frontal airbag.
But these airbags must inate very quickly to do their
job and comply with federal regulations.
1-58

Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are “supplemental
restraints” to the safety belts. Airbags are
designed to work with safety belts, but do not
replace them. Airbags are designed to deploy
in moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear crashes, or in many side crashes.
And, for some unrestrained occupants, airbags
may provide less protection in frontal crashes
than more forceful airbags have provided in
the past. Everyone in your vehicle should wear
a safety belt properly — whether or not there
is an airbag for that person.
{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. If you are too close to an
inating airbag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position before
and during a crash. Always wear your safety
belt, even with airbags. The driver should sit
as far back as possible while still maintaining
control of the vehicle.
1-59

{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
seeOlder Children on page 1-32andInfants
and Young Children on page 1-35.
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 3-32
for more information.
Where Are the Airbags?
The driver’s airbag is in the middle of the
steering wheel.
1-60

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.
1-61

When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level is
about 9 to 17 mph (14 to 27 km/h). (The threshold level
can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.)Frontal airbags may inate at different crash speeds.
For example:If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbags could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts.
1-62

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 4-16for 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. Airbags supplement 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.
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 bag that come into contact
with you may be warm, but not too hot to touch. There will
be some smoke and dust coming from the vents in the
deated airbags.
1-63

Airbag ination does not prevent the driver from seeing
out of the windshield or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is 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 and turn the interior lamps on when
the airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After they
inate, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-10.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.
