These models are fitted with a Supplemental Occupational Restraint System (SRS), also known as air bags, used in preventing the driver and passer from serious injury during incidences of an accident. INC unit is installed in all models under the center console; diagnostic control unit is present. These modules come as a housing that contains the airbag and the inflator unit in which the inflator assembly is fixed at the back of the housing to enable fast inflation once an electrical signal is received. A "clock spring" relays this signal irrespective of the position of the steering wheel, while airbag modules are located in the steering wheel, over the glove compartment and at the roof rails. The diagnosis /sensor unit consists of a micro processor along with a crash sensor and is integrated to monitor the working of the system and checks it every time when the vehicle is started and the 'AIRBA"G light will glow to indicate that the system is functional. If a fault is diagnosed, the light stays on, ensuring that persons realize that service is required as soon as possible. The crash zone sensor is on radiator support and the side curtain air bags sensor is on the "B" Pillar of each door. This is because air bags must be deployed through impact sensors that would complete the circuit to the inflator. A self-diagnosis circuit turns a light on the instrument panel when the ignition is on through the
Instrument Cluster, and this light should go off after five seconds if all is well; any difficulty explains that the instrument needs to be checked. Regarding servicing, care should be taken when working near the SRS system; to disconnect the SRS airbag system, the steering wheel should be positioned to dead ahead, the ignition turned to the Lock position, and the battery cables disconnected for ten minutes. Some of these include the way that after servicing, the requisite connectors can be connected to get the airbag system active again and to make sure that the airbag warning light practices as it should. Replacement of the driver's side airbag and clockspring as well as the passenger side airbag and side curtain airbags require certain procedures such as disabling the specific units in the car, disconnecting and reconnecting restored and new components in the car. Furthermore, all models employ pyrotechnic units in the front seat belt retractors that in event of an impact it tightens the occupant's seat belt preparing for an impact and therefore the SRS system must be turned off during any work within the area of the seats.
