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 2-73 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.
