80 Seats and Restraints
When the passenger sensing
system has allowed the airbag
to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbag
is 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, 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
(Continued)
Warning (Continued)
the vehicle serviced right
away. See Airbag Readiness
Light0132 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 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:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers. 4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Rear Seat) 0102
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 104.
Make sure the seat belt
retractor is locked by
pulling the shoulder belt all
the way out of the
retractor when installing
the child restraint, even if
the child restraint is
equipped with a seat belt
lock off. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
5. If, after reinstalling the child restraint and
restarting the vehicle, the
ON indicator is still lit, turn
the vehicle off. Then
slightly recline the vehicle

seatback and adjust the
seat cushion, if adjustable,
to make sure that the
vehicle seatback is not
pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped
under the vehicle head
restraint. If this happens,
adjust the head restraint.
See Head Restraints047.
6. Restart the vehicle.
The passenger sensing
system may or may not turn
off the airbag for a child in a
child restraint depending upon
the child’s size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in
the front seat, even if the ON
indicator is not lit.If the Off Indicator Is Lit
for an Adult-Sized
Occupant
If a person of adult size is
sitting in the front outboard
passenger seat, but the OFF
indicator is lit, it could be
because that person is not
sitting properly in the seat or
that the child restraint locking
feature is engaged. Use the
following steps to allow the
system to detect that person
and enable the front outboard
passenger frontal airbag: 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. 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 off for
some adult-sized
occupants. If this happens,
unbuckle the belt, let the
belt go back all the way,
and then buckle the belt
again without pulling the
belt out all the way.

6. Restart the vehicle andhave the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat 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
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
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 specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 083
for more information about
modifications that can affect
how the system operates.
The ON indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is 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 Information
0476.

{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. 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
