Every model comes with an SRS, which is also known as airbags and the purpose it serves is to shield any driver or passenger in the front seat that may be involved in a head on collisions. This comprises of an airbag module on the steering wheel and probably another one on the instrument panel. Side-impact airbags are equipped on certain models while others have side curtain airbags and pre-tensioners for the seat belts. The cushion and inflater unit which inflate the bag instantly once an electric signal is sent are contained in the airbag inflater module located in the steering wheel. The passenger-side airbag has a housing, inflator, bag assembly, trim cover, mounted above a glove compartment. While driving along streets, there are side-impact airbags mounted to outer sides of front seat backs whereas side curtain air bags line across their headliner from above door openings. During a crash, an Air Bag Control Module sends current through wires in system & checks computer every time car starts up. When performing maintenance near components such as steering wheel etc., it becomes necessary to disable SRS systems. If you ever handle an airbag module, keep the opening away from yourself plus place it flatly with its opening facing upwards; never measure resistance of any SRS component and avoid unplugging any yellow connectors relating to your vehicle's safety bags unless you must do so otherwise. Extreme caution should be used when working around front impact sensors: do not use electric welding equipment without first disconnecting battery cables.
