Athicklayerofadditionalmaterial,such as a blanket or cushion,or aftermarket equipment such asseat covers, seat heaters, and seatmassagers can affect how well thepassenger sensing systemoperates. We recommend that younot use seat covers or otheraftermarket equipment except whenapproved by GM for your specific
vehicle. SeeAdding Equipment tothe Airbag-Equipped Vehicle075for more information aboutmodifications that can affect howthe system operates.
The on indicator may be lit if anobject, such as a briefcase,handbag, grocery bag, laptop,or other electronic device, is put onan unoccupied seat. If this is notdesired, remove the object fromthe seat.

or very close to, any airbag when

For each type of child restraint,there are many different modelsavailable. When purchasing a childrestraint, be sure it is designed to beused in a motor vehicle. If it is, therestraint will have a label saying thatit meets federal motor vehicle safetystandards. The restraintmanufacturer's instructions thatcome with the restraint state theweight and height limitations for aparticular child restraint. In addition,there are many kinds of restraintsavailable for children with specialneeds.
