In many crashes severe enough to inate the 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 the
airbag system. If you do not get them, the airbag
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.
The vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 8-16andEvent Data Recorders on page 8-17.
Let only qualied technicians work on the airbag
system. Improper service can mean that the airbag
system will not work properly. See your dealer/
retailer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible in the rearview mirror
when the vehicle is started.The words ON and OFF, or the symbol for on and off,
will be visible during the system check. When the system
check is complete, either the word ON or OFF, or the
symbol for on or off, will be visible. SeePassenger Airbag
Status Indicator on page 3-45. United States
Canada
1-45

The passenger sensing system is designed to turn off
the right front passenger frontal airbag and seat-mounted
side impact 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 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
right front passenger frontal airbag, and seat-mounted
side impact airbag, the off indicator will light and stay lit
to remind you that the airbag(s) are off. SeePassenger
Airbag Status Indicator on page 3-45.The passenger sensing system is designed to turn on
(may inate) the right front passenger frontal airbag and
seat-mounted side impact airbag anytime the system
senses that a person of adult size is sitting properly in
the right front passenger seat.
When the passenger sensing system has allowed the
airbags to be enabled, the on indicator will light and stay
lit to remind you that the airbags are 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 frontal
airbag and seat-mounted side impact airbag, depending
upon the person’s seating posture and body build.
Everyone in the vehicle who has outgrown child restraints
should wear a safety belt properly — whether or not there
is an airbag for that person.{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-44
for more information, including important safety
information.

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 8-15.
{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,
the inside review mirror, front sensors, 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.
1-50

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 the
seat 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 1-45.
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 8-2.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 8-2.
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 3-44for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 6-76.
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 3-44for 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, see
What Makes an Airbag Inflate? on page 1-43.
See your dealer/retailer for service.
