GMC 2009 Savana - Manual (Page 80)

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.
If you ever pull the shoulder portion of the belt out all
the way, you will engage the child restraint locking
feature. This may unintentionally cause the passenger
sensing system to turn the airbag(s) off for some
adult size occupants. If this happens, just let the
belt go back all the way and start again.
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.
{ 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.
