2007 HUMMER H3 ECU

{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 39orInfants and Young Children
on page 42.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 178for more information.

{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. And, if your vehicle
has roof-mounted side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening.
If you do, the path of an inating side
impact airbag will be blocked. The path
of an inating airbag must be kept clear.
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.
In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according
to crash severity. Your vehicle has electronic
frontal sensors, which help the sensing system
distinguish between a moderate frontal impact
and a more severe frontal impact. For moderate
frontal impacts, these airbags inate at a level
less than full deployment. For more severe
frontal impacts, full deployment occurs.
71

The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s frontal
airbag should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the
front seat. We recommend that child restraints be
secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{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.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
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. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If you need to 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.
76

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is
present in a rear-facing infant seat.
The system determines that a small child is
present in a forward-facing child restraint.
The system determines that a small child is
present in a booster seat.
A right front passenger takes his/her weight
off of the seat for a period of time.
the right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s frontal airbag, the off indicator
on the instrument panel will light and stay lit to
remind you that the airbag is off.If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child
restraint following the child restraint manufacturer’s
directions and refer toSecuring a Child Restraint in
the Right Front Seat Position on page 60.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the
child restraint into the seat cushion. If this happens,
slightly recline the vehicle’s seatback and adjust the
seat cushion if possible. Also make sure the child
restraint is not trapped under the vehicle head
restraint. If this happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle
and check with your dealer.
The passenger sensing system is designed to
enable (may inate) the right front passenger’s
frontal airbag anytime the system senses that a
person of adult size is sitting properly in the right
front passenger’s seat. When the passenger
sensing system has allowed the airbag to be
enabled, the on indicator will light and stay lit to
remind you that the airbag is active.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides 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 the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure
on page 448.
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, rollover sensor
module, instrument panel, steering wheel,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted rollover airbag modules, 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 448.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.To activate the content theft-deterrent system, do
the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry
transmitter is pressed, but a door is open,
the doors will lock, the lights may ash and the
horn may sound. Close the open door and
the alarm system will arm.
If a locked door is not opened using the remote
keyless entry transmitter, or by OnStar
®, the alarm
will go off. First, a pre-alarm will sound the horn
at reduced intensity for 10 seconds. Then, the front
turn signal lamps will ash for two minutes, and
the horn will sound for two minutes. The alarm will
then turn off to save battery power.
Starting the engine with the correct key will shut
off the pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not
activate if you lock the doors with the key,
the manual door lock, or power door lock switch.

Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or
the ignition lock cylinder is tampered with, the fuel
system is disabled and the vehicle will not start.
During normal operation, the security light will turn
off approximately ve seconds after the engine
is started. SeeSecurity Light on page 190.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your Passlock
®
system is not working properly and must be
serviced by your dealer. Your vehicle is not
protected by Passlock
®at this time. See your
dealer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 454.
