These models have a Supplemental Restraint System (SRS), also referred to as airbags, which are incorporated to distribute the driver and the passenger against severe injury during a head-on or side impact and a diagnostic control unit is installed below the center console. The steering wheel contains the airbag of the driver which is inflated by an inflater module that is activated when an electrical signal is received by the inflater module, which is delivered by a spiral cable that provides connectivity to the inflater module regardless of the position of the steering wheel. The airbag of the passenger is above the glove box, in the instrument panel, which is made similarly, but larger and is also textured with a textured trim cover, when in the act of inflation. Certain models have some form of side-impact airbags on the rear seat backs and built-in rear seat bolsters and also provide secondary protection with side-curtain airbags that are deployed through the headliner during a side impact. The airbag system is activated by the sensing and diagnostic module when there is a collision and functionality is checked upon the activation of the vehicle starter which is shown by the light- AIR BAG. In case a fault is found, the light would be kept on or flashing and it would require immediate service. The models consist of all having pyrotechnic units in front seat belt retractors that cinch the belts in an event of an impact. The most important is to turn off the airbag system during maintenance of the areas around the seat or the SRS components, and this means that one has to straighten the steering wheel, lock the ignition, disconnect the negative battery cable, and wait two minutes. One can re-arm the system by simply turning on the ignition without any one in the vehicle, after which the battery cable is reconnected and the "AIR BAG" light is checked to make sure it works properly. Airbag modules are delicate to handle and though the passenger airbag module could be left in place when removing the instrument panel, I would recommend letting the professionals handle airbag modules.
