THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51 Airbag System Components The airbag system consists of the following: • Occupant Restraint Control (ORC) • Airbag Warning Light • Driver Airbag • Passenger Airbag • Side Curtain Airbags above Side Windows • Side Remote Acceleration Sensors • Driver Side Seat Track Position Sensor • Steering Wheel and Column • Instrument Panel • Interconnecting Wiring • Knee Impact Bolsters • Front Acceleration Sensors • Driver and Front Passenger Seat Belt Pretensioners How the Airbag System Works • The Occupant Restraint Control (ORC) determines if a frontal, side, or rollover collision is severe enough to require the front and/or side airbags to inflate. The front airbag inflators are designed to provide different rates of airbag inflation from direction provided by the ORC. The ORC will detect roll overs, not rear impacts. The ORC also monitors the readiness of the electronic parts of the system whenever the ignition switch is in the START or ON positions. These include all of the items listed above except the knee bolster, the instrument panel, and the steering wheel and column. If the key is in the LOCK position, in the ACC position, or not in the ignition, the airbags are not on and will not inflate. 2
