2009 HUMMER H2 Owners Manual

Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

Causes the passenger airbag to pose a special risk
for the passenger; and
Makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.
{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 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.To turn off the right front passenger frontal airbag, insert
the ignition key into the switch, push in, and move the
switch to the off position.
The word OFF or the off symbol will come on in the
passenger airbag status indicator located in the
overhead console to let you know that the right front
passenger airbag is off, after the system check is
completed. The airbag off light will come on and stay on
to let you know that the right front passenger airbag
is off. SeeAirbag Off Light on page 3-33. United States
Canada
1-77

The airbag off light will stay on to remind you that the
airbag is off. The right front passenger airbag will remain
off until you turn it back on again.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. For example, the right
front passenger airbag could inate even though
the airbag on-off switch is turned off.
To help avoid injury to yourself or others, have the
vehicle serviced right away. SeeAirbag Readiness
Light on page 3-32for more information, including
important safety information.To turn the right front passenger airbag on again, insert
the ignition key into the switch, push in, and move
the switch to the on position.
The right front passenger’s frontal airbag is now
enabled (may inate). SeeAirbag Off Light on page 3-33
for more information.United States

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.
1-79

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: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. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.
Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired.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.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-32for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-105.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-32for more information.
Notice:If an airbag covering is damaged, opened, or
broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, seeWhat Makes an
Airbag Inflate? on page 1-73. See your dealer/retailer
for service.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced.
If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was
not being used at the time of the crash.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. SeeAirbag Readiness Light on page 3-32.
