If the ON light appears, it means that the right front passenger's frontal air bag is on. CAUTION: United States Canada If the ON light comes on when you have a child restraint installed in the right front passenger seat, it means that the AOS system has not turned off the right front passenger's frontal and side impact air bags. If this ever happens and you're using a rear-facing infant restraint, perform the steps to install the restraint again. See "Securing a Child Restraint in the Right Front Seat Position" in the Index. If the air bags still don't turn off, install the infant restraint in a rear seat position and have your vehicle serviced as soon as possible. Don't use a rear-facing infant restraint in the right front passenger's seat unless the air bag has been turned off. CAUTION: If the air bag readiness light ever comes on, it means that something may be wrong with the air bag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting there may not have the protection of the air bags. See "Air Bag Readiness Light" in the Index for more on this, including important safety information. 2-78
