ECU HUMMER H2 2009 Owner's Manual

6. If the child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding the
use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-51for
more information.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle safety
belt and let it return to the stowed position. If the top
tether is attached to a top tether anchor, disconnect it.
Securing a Child Restraint in the
Right Front Seat Position
This vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-50.
There is a switch in the glove box that you can use to
turn off the right front passenger frontal airbag. See
Airbag Off Switch on page 1-76for more information,
including important safety information.
A label on the 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 airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inates and the passenger seat is in a forward
position.
Even if the airbag switch has turned off the right
front passenger frontal airbag, no system is
fail-safe. No one can guarantee that an airbag will
not deploy under some unusual circumstance,
even though it is turned off.
Secure rear-facing child restraints in a 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.
1-64

{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. SeeAirbag Off
Switch on page 1-76andAirbag Readiness Light
on page 3-32for more on this, including important
safety information.
If your child restraint has the LATCH system, seeLower
Anchors and Tethers for Children (LATCH) on page 1-51
for how and where to install the child restraint using
LATCH. If a child restraint is secured using a safety belt
and it uses a top tether, seeLower Anchors and Tethers
for Children (LATCH) on page 1-51for top tether anchor
locations.Do not secure a child restraint in a position without a
top tether anchor if a national or local law requires that
the top tether be anchored, or if the instructions that
come with the child restraint say that the top strap must
be anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions that
came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
If you have no other choice but to install a
rear-facing child restraint in this seat, make sure
the airbag is off once the child restraint has
been installed.
When the airbag off switch has turned off the right
front passenger frontal airbag, the off indicator in the
airbag off light should light and stay lit when you start
the vehicle. SeeAirbag Off Light on page 3-33.
2. Put the child restraint on the seat.
If the seat has a safety belt guide, remove the safety
belt from the guide by sliding the webbing through
the opening on the guide. Do not secure the child
restraint with the safety belt routed through the guide.
1-65

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. When installing a forward-facing
child restraint, it may be 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.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.If you turned the airbag off with the switch, turn on the
right front passenger airbag when you remove the child
restraint from the vehicle unless the person who will be
sitting there is a member of a passenger airbag risk
group. SeeAirbag Off Switch on page 1-76for more
information, including important safety information.
Airbag System
The vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right
front passenger.
The vehicle may have the following airbags:
If your vehicle has a third row seat, it will have third
row roof-rail airbags.
All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
1-67

{CAUTION:
Children who are up against, or very close to, any
airbag when it inates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, 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 1-40or
Infants and Young Children on page 1-43.
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 3-32for
more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-69

If your vehicle has roof-rail airbags and a third row
passenger seat, the airbags are located in the ceiling
above the rear windows for the outboard passenger
positions in the third row.
{CAUTION:
If something is between an occupant and an
airbag, the airbag 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.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inating roof-rail airbag will be
blocked. Driver Side shown, Passenger Side similar

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inate during improper service. You can be injured
if you are close to an airbag when it inates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about 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. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, overhead console, front
sensors, side impact sensors, rollover sensor
module, or airbag wiring can affect the operation of
the airbag system.
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 7-2.
If your vehicle has rollover roof-rail airbags, seeDifferent
Size Tires and Wheels on page 5-74for additional
important information.
