Seating and Safety Restraints Your vehicle's Personal Safety System consists of: • Driver and passenger dual-stage airbag supplemental restraints. • Front outboard safety belts with pretensioners, energy management retractors (first row only), and safety belt usage sensors. • Driver's seat position sensor. • Front passenger sensing system • "Passenger airbag off" or "pass airbag off" indicator lamp • Front crash severity sensor. • Restraints Control Module (RCM) with impact and safing sensors. • Restraint system warning light and back-up tone. • The electrical wiring for the airbags, crash sensor(s), safety belt pretensioners, front safety belt usage sensors, driver seat position sensor, front passenger sensing system, and indicator lights. How does the Personal Safety System work? The Personal Safety System can adapt the deployment strategy of your vehicle's safety devices according to crash severity and occupant conditions. A collection of crash and occupant sensors provides information to the Restraints Control Module (RCM). During a crash, the RCM activates the safety belt pretensioners and/or either one or both stages of the dual-stage airbag supplemental restraints based on crash severity and occupant conditions. The fact that the pretensioners or airbags did not activate for both front seat occupants in a collision does not mean that something is wrong with the system. Rather, it means the Personal Safety System determined the accident conditions (crash severity, belt usage, etc.) were not appropriate to activate these safety devices. Front airbags are designed to activate only in frontal and near-frontal collisions (not rollovers, side impacts or rear impacts) unless the collision causes sufficient longitudinal deceleration. The pretensioners are designed to activate in frontal and near-frontal collisions, and in side collisions and rollovers. Driver and passenger dual-stage airbag supplemental restraints The dual-stage airbags offer the capability to tailor the level of airbag inflation energy. A lower, less forceful energy level is provided for more common, moderate-severity impacts. A higher energy level is used for the most severe impacts. Refer to Airbag supplemental restraints (SRS) section in this chapter. 126 2009 Sable (mgo) Owners Guide, 2nd Printing USA (fus)
