66 Seats and Restraints
systems are damaged in the
crash they may not operate as
normal.
{Warning
A crash severe enough to
inflate the airbags may have
also damaged important
functions in the vehicle, such
as the brake and steering
systems, etc. Even if the
vehicle appears to be
drivable after a moderate
crash, there may be
concealed damage that
could make it difficult to
safely operate the vehicle.
Use caution if attempting to
restart the vehicle after a
crash has occurred.
Plug-in vehicles have a high
voltage battery and a
standard 12-volt battery.
If an airbag inflates or the
vehicle has been in a crash,
the sensing system may shut
down the high voltage system. When this occurs, the high
voltage battery is
disconnected and the vehicle
will not start. Before the
vehicle can be operated again,
it must be serviced at your
dealer.
In many crashes severe
enough to inflate the airbag,
windshields are broken by
vehicle deformation. Additional
windshield breakage may also
occur from the front outboard
passenger airbag.
.Airbags are designed to
inflate only once. After an
airbag inflates, 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 the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy
0397 and
Event Data Recorders 0398.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.

68 Seats and Restraints
Warning (Continued)
always move the seat as far
back as it will go. It is better
to secure child restraints in
the rear seat. Consider
using another vehicle to
transport the child when a
rear seat is not available.
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee
airbag if:
.The front outboard
passenger seat is
unoccupied.
.The system determines an
infant is present in a child
restraint.
.A front outboard passenger
takes his/her weight off of
the seat for a period of time.
When the passenger sensing
system has turned off the
front outboard passenger
frontal airbag and knee airbag,
the OFF indicator will light and stay lit as a reminder that the
airbags are off. See Passenger
Airbag Status Indicator
0113.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal airbag and knee airbag,
anytime the system senses
that a person of adult size is
sitting properly in the front
outboard passenger seat.
When the passenger sensing
system has allowed the
airbags to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbags
are active.
For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat belt properly
—whether or not
there is an airbag for that
person.
{Warning
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. See Airbag Readiness
Light 0112 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee airbag,
if the system determines that
an infant is present in a child
restraint. If a child restraint
has been installed and the ON
indicator is lit:

Seats and Restraints 71
put on an unoccupied seat.
If this is not desired, remove
the object from the seat.
{Warning
Stowing 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 the
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 and the
service manual have
information about servicing
the vehicle and the airbag
system. To purchase a service
manual, see Publication
Ordering Information0394.
{Warning
For up to 10 seconds after
the vehicle is turned off and
the battery is disconnected,
an airbag can still inflate
during improper service. You
can be injured if you are
close to an airbag when it
inflates. 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
qualified to do so.
Adding Equipment to
the Airbag-Equipped
Vehicle
Adding accessories that
change the vehicle's frame,
bumper system, height, front
end, or side sheet metal may
keep the airbag system from
working properly. The operation of the airbag
system can also be affected
by changing, including
improperly repairing or
replacing, any parts of the
following:
.Airbag system, including
airbag modules, front or side
impact sensors, sensing and
diagnostic module, or airbag
wiring
.Front seats, including
stitching, seams or zippers
.Seat belts
.Steering wheel, instrument
panel, overhead console,
ceiling trim, or pillar
garnish trim
.Inner door seals, including
speakers
Your dealer and the service
manual have information about
the location of the airbag
modules and sensors, sensing
and diagnostic module, and
airbag wiring along with the
proper replacement
procedures.

72 Seats and Restraints
In addition, the vehicle has a
passenger sensing system for
the front outboard 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 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). See
Passenger Sensing System
066. If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
0352
for additional important
information.
If the vehicle must be modified
because you have a disability
and have questions about
whether the modifications will
affect the vehicle's airbag
system, or if you have
questions about whether the
airbag system will be affected
if the vehicle is modified for
any other reason, call
Customer Assistance. See
Customer Assistance Offices
0 386.
Airbag System Check
The airbag system does not
need regularly scheduled
maintenance or replacement.
Make sure the airbag
readiness light is working. See
Airbag Readiness Light 0112.
Caution
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 coverings,
have the airbag covering
and/or airbag module
replaced. For the location of
the airbags, see Where Are
the Airbags? 061. See your
dealer for service.
