CHEVROLET TAHOE 2005 2.G Manual Online

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. For frontal airbags, ination is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal and near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.
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 4-22for 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. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, the airbag and related hardware
are all part of the airbag modules. Frontal airbag modules
are located inside the steering wheel and instrument
panel. For vehicles with side impact airbags, the airbag
modules are located in the seatback closest to the
driver’s and/or right front passenger’s door.
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. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements 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 the
frontal 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 the airbag. Side impact airbags would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear 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 for the driver’s and right front passenger’s
frontal airbags, and only in moderate to severe
side collisions for vehicles with a driver’s and right front
passenger’s side impact airbag.

What Will You See After an Airbag
Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal airbag and the
instrument panel for the right front passenger’s frontal
airbag. For vehicles with side impact airbags, the side of
the seatback closest to the driver’s and/or right front
passenger’s door will be hot. 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.
Airbag ination does not prevent the driver from seeing
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.
1-76

In many crashes severe enough to inate an 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 an
airbag inates, you will need some new parts for
your airbag system. If you do not get them, the air
bag 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 7-9.
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.Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the airbag
covering on the driver’s and right front passenger’s
seatback, the airbag may not work properly. You
may have to replace the airbag module in the
steering wheel, both the airbag module and the
instrument panel for the right front passenger’s
airbag, or both the airbag module and seatback for
the driver’s and right front passenger’s side
impact airbag. Do not open or break the airbag
coverings.

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a
passenger sensing system. The indicator will be visible
when you turn your ignition key to START or RUN.
The words ON and OFF or the symbol for on and off,
will be visible on the rearview mirror during the system
check. When the system check is complete, either
the word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 3-40. If your rearview
mirror does not have either of the indicators pictured,
then your vehicle does not have the passenger sensing
system.The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side 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.
General Motors recommends 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. Passenger Airbag Status Indicator – United States
Passenger Airbag Status Indicator – Canada
1-78

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. General Motors
recommends that rear-facing child restraints
be secured in the rear seat, even if the airbag
is off.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 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 1-64.
1-79

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.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety
belt properly — whether or not there is an airbag for that
person.If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about
two minutes. This will allow the system to detect that
person and then enable the passenger’s airbag.
1-80

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-39for more on this, including
important safety information.Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-82for more
information about modications that can affect how the
system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
1-81

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are airbag system parts in several places around
your vehicle. You do not want the system to inate
while someone is working on your vehicle. Your dealer
and the service manual have information about
servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key 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.
The airbag system does not need regular maintenance.
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, front end or side sheet
metal or height, 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 7-2.
1-82

Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my advanced airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the advanced 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 7-2.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, 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.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
1-83

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 you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if
worn during a more severe crash, then you need
new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
