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 specific
vehicle. See Adding Equipment to Your Airbag-Equipped
Vehicle on page 1-78 for more information about
modifications 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. See Airbag
Readiness Light on page 3-30 for 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.
