The passenger sensing system works with sensors that are part of the right front passenger's seat and safety belt. The sensors are designed to detect the presence of a properly-seated occupant and determine if the passenger's frontal air bag should be enabled (may inflate) or not. Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors, therefore, recommends that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. Never put a child in rear-facing child restraint in the right front passenger seat unless your vehicle has the passenger sensing system and the passenger air bag status indicator shows off. Never put a rear-facing child restraint in the right front passenger seat unless the air bag is off. {CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger's air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure the air bag is off before using a rear-facing child restraint in the right front seat position. Even though the passenger sensing system is designed to turn off the passenger's frontal air bag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though it is turned off. General Motors, therefore, recommends that rear-facing child restraints be secured in the rear seat whenever possible, even if the air bag is off. 1-82
