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.
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 speci c
vehicle. SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 1-78for more information about
modi cations that can affect how the system operates.
A wet seat can affect the performance of the passenger
sensing system. Here is how:
The passenger sensing system may turn off the
passenger airbag when liquid is soaked into the seat.
If this happens, the off indicator will be lit, and the
airbag readiness light on the instrument panel will
also be lit.
Liquid pooled on the seat that has not soaked in
may make it more likely that the passenger sensing
system will enable (turn on) the passenger airbag
while a child restraint or child occupant is on the seat.
If the passenger airbag is turned on, the on indicator
will be lit.
If the passenger seat gets wet, dry the seat immediately.
If the airbag readiness light is lit, do not install a child
restraint or allow anyone to occupy the seat. SeeAirbag
Readiness Light on page 3-30for important safety
information.
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.
{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.

When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-31.
The passenger sensing system is designed to turn
on (may in ate) the right front passenger 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 frontal
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 3-30
for more information, including important safety
information.

If the On Indicator is Lit for 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 toSecuring a Child Restraint in the Right Front
Seat Position on page 1-54.5. 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. SeeHead Restraints
on page 1-7.
6. Restart the vehicle.
If the on indicator is still lit, secure the child restraint
in a rear seat position in the vehicle, and check
with your dealer/retailer.
