42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE • Front Acceleration Sensors • Driver and Front Passenger Seat Belt Pretensioner • Occupant Classification System (OCS) - Front Passenger Seat Only − Occupant Classification Module − Passenger Airbag Disable (PAD) Indicator Light − Weight Sensors How The Airbag System Works • The Occupant Restraint Control (ORC) Module determines if a frontal collision is severe enough to require the airbags to inflate. The front airbag inflators are designed to provide different rates of airbag inflation from direction provided by the ORC. The ORC may also modify the rate of inflation based on the occupant size provided by the Occupant Classification Module. The ORC will not detect roll over, or 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. Also, the ORC turns on the "Airbag Warning Light" and "PAD Indicator Light" for 6 to 8 seconds for a self-check when the ignition is first turned on. After the self-check, the "Airbag Warning Light" will turn off. The "PAD Indicator Light" will function normally (Refer to ЉPassenger Airbag Disable (PAD) Indicator LightЉ in this
