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 1-72 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 3-28 for important safety
information.
