2007 Chevrolet Cobalt Owner's Manual - Page 79

If your vehicle does not have the passenger sensing system, the right front passenger's frontal airbag will deploy in collisions that are severe enough to deploy the frontal airbags, regardless of the size of the occupant in the right front passenger seat. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger's seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 163 for more on this, including important safety information. Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system. See Adding Equipment to Your Airbag-Equipped Vehicle on page 81 for more information about modifications that can affect how the system operates. {CAUTION: Stowing of articles under the passenger's seat or between the passenger's seat cushion and seatback may interfere with the proper operation of the passenger sensing system. 79
