The system includes: a driver airbag module located in the steering wheel hub and consisting of a folded airbag shell and a gas generator; passenger airbag module, located in the instrument panel on the passenger side and consisting of a folded airbag shell and a gas generator; side airbag modules located in the backrest of the driver and passenger seats and consisting of a folded airbag shell and a gas generator; an electronic control unit (ECU) installed in the center console and controlling the system; accelerometer measuring the negative acceleration of a vehicle; a spring-loaded connecting element (contact disk) located in the steering column; wiring and system connectors; soft knee padding located under the steering column. The impact force detection function is provided by the ECU using an electronic accelerometer, which continuously measures the vehicle's acceleration and sends a corresponding signal to the microprocessor via the amplifying and filtering circuits. The airbag is triggered in the event of a moderate to severe frontal or near-frontal side impact.
Only specially trained personnel are allowed to perform work on the airbag system. Therefore, such work must be preceded by a careful study of this Manual. When performing work on the airbag system, strict safety precautions must be taken to prevent injury to service personnel (in case of accidental airbag deployment) or the driver (due to airbag failure).
The driver airbag module (DAM), passenger airbag (PAM), includes the airbag itself and a gas generator. The gas generator is made in the form of a pyropatron with an igniter. In the event of a frontal or side impact of sufficient force, causing the ECU sensor contacts to close, current is supplied to the ignition circuit, resulting in the pyropatron being ignited and the airbag being filled with gas.
1. When removing the airbag module or handling a new airbag module, place the module with the outer trim facing up. The airbag module wire connector dual lock lever must be in the locked position and positioned so as not to damage the connector. Do not store steering wheel trims stacked on top of each other. (Storing the trims with the metal part facing up may cause an accident if the airbag is accidentally deployed.).
2. It is prohibited to check the resistance at the igniter terminals (this may cause the airbag to deploy, which is extremely dangerous).

3. Store the airbag module at a temperature not exceeding 93°C in conditions of normal humidity and absence of electrical interference.
4. Before performing electric welding work, it is necessary to disconnect the airbag wire connector located under the steering column next to the steering column switch unit connector.
