2013 Chevrolet Volt Owner Manual - Page 80

3-28 Seats and Restraints Your dealer and the service manual have information about the location of the airbag sensors, sensing and diagnostic module, and airbag wiring. In addition, the vehicle has a passenger sensing system that includes sensors as part of the front outboard passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing system from properly turning off the passenger airbag(s). See Passenger Sensing System on page 3‑23. If the vehicle has rollover roof‐rail airbags, see Different Size Tires and Wheels on page 10‑56 for additional important information. If your vehicle needs to be modified because you have a disability and you have questions about whether the modifications will affect the vehicle's airbag system, or if you have questions about whether the airbag system will be affected if the vehicle is modified for any other reason, call Customer Assistance. See Customer Assistance Offices on page 13‑3. WARNING (CONTINUED) service procedures, and make sure the person performing work for you is qualified to do so.

The operation of the airbag system can also be affected by changing or moving any parts of the front seats, safety belts, airbag sensing and diagnostic module, steering wheel, instrument panel, roof-rail airbag modules, ceiling or pillar garnish trim, overhead console, front sensors, side impact sensors, rollover sensor module, or airbag wiring. Airbag System Check The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light on page 5‑16. Notice: If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag
