Additional passive safety system (SRS) designed to be used in conjunction with seat belts to improve safety in crashes and reduce the risk of injury from front and side airbag deployment by keeping front passengers seated in the event of a frontal or side impact.
Additional passive safety system (SRS) consists of the following elements: driver front airbag (located in the center of the steering wheel), which contains a module with a folded airbag and an inflatable device (gas generator); front passenger airbag (located in the instrument panel on the passenger side), which contains a module with a folded airbag and an inflatable device (gas generator); side airbags (located in the outer sidewalls of the backrests of the driver's and front passenger's seats), each containing a folded airbag module and an inflator (gas generator); electronic control unit SRS (installed under the center of the floor console), which controls the entire system; acceleration sensor (accelerometer), which determines the deceleration of the car (impact from outside); clock spring intermediate connection located in the steering column; electrical wiring and system connectors; knee buffer (knee bolster), located under the steering column. The external impact detection function in the SRS ECU is performed by an electronic acceleration sensor, which constantly measures the vehicle's acceleration and transmits the corresponding signal through the amplifying and filtering circuits to the microprocessor. Additional passive safety system (SRS) designed in such a way that the airbags will deploy in the event of an accident in frontal or near-frontal impacts of varying severity (medium to strong).
To work on maintenance of additional passive safety systems (SRS), as well as related items, are allowed only by qualified personnel. Service personnel should carefully read this manual before starting work. Special care must be taken when servicing the SRS system to avoid injury or death to service personnel (as a result of unauthorized deployment of the airbag), or the driver (as a result of the inoperability of the SRS system after unskilled service or repair).
