The front passenger seat in many GM vehicles is equipped with a passenger sensingsystem that will turn off the right front passenger's frontal airbag under certainconditions, such as when an infant or child seat is present. In some vehicles, thepassenger sensing system will also turn off the right front passenger's seat mountedside impact airbag. For the system to function properly, sensors are used in the seatto detect the presenceof a properly-seated occupant. The passenger sensing system may not operate properlyif the original seat trim is replaced (1) by non-GM covers, upholstery or trim, or(2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GMcovers, upholstery or trim that has been altered by a trim shop, or (4) if any object,such as an aftermarket seat heater or a comfort enhancing pad or device is installedunder the seat fabricor between the occupant and the seat fabric.Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices
