HUMMER H3 2009 Repair Manual

If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in
the right front passenger seat, but
the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
use the following steps to allow thesystem to detect that person and
enable the right front passenger
frontal airbag and seat-mounted side
impact airbag (if equipped):
1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
3. Place the seatback in the fully
upright position.
4. Have the person sit upright in
the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the
person remain in this position for
two to three minutes after the
on indicator is lit.
Additional Factors Affecting
System Operation
Safety belts help keep the passenger
in position on the seat during vehicle
maneuvers and braking, which helps
the passenger sensing system
maintain the passenger airbag
status. See “Safety Belts” and “Child
Restraints” in the Index for additional
information about the importance of
proper restraint use.
If the shoulder portion of the belt is
pulled out all the way, the child
restraint locking feature will be
engaged. This may unintentionally
cause the passenger sensing system
to turn the airbag(s) off for some
adult size occupants. If this happens,
just let the belt go back all the way
and start again.
Seats and Restraint System 1-57

A thick layer of additional material,
such as a blanket or cushion, or
aftermarket equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that you
not use seat covers or other
aftermarket equipment except when
approved by GM for your specic
vehicle. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on
page 1-58for more information
about modications that can affect
how the system operates.
{CAUTION
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
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.
(Continued)
CAUTION (Continued)
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 the 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
1-58 Seats and Restraint System

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.
In addition, the vehicle has a
passenger sensing system for the
right front passenger position,
which includes sensors that are
part of the passenger seat.
The passenger sensing system
may not operate properly if the
original seat trim is replaced with
non-GM covers, upholstery or
trim, or with GM covers,
upholstery or trim designed for a
different vehicle. Any object, such
as an aftermarket seat heater or a
comfort enhancing pad or device,
installed under or on top of theseat fabric, could also interfere
with the operation of the
passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger
Sensing System on page 1-54.
If you have any 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 7-1.
If the vehicle has rollover
roof-rail airbags, seeDifferent
Size Tires and Wheels on
page 5-61for additional
important information.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. SeeCustomer
Satisfaction Procedure on
page 7-1.
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 3-24for more
information.Keep safety belts clean and dry.
SeeCare of Safety Belts on
page 5-85.
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 3-25for 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 1-52. 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.
1-60 Seats and Restraint System

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 3-25.
