Purpose and function in the vehicle

The seat airbag is designed for installation in the front driver's seat on the left side in W213, C238, and W257 series vehicles. This component works with crash sensors and the airbag control unit, activating in a fraction of a second in the event of a side or frontal collision, in accordance with the logic of the Mercedes safety system. As a result, the driver receives an additional layer of protection within the seat area, which reduces the forces acting on the body.

As part of the Other seat parts group, the seat airbag is a key addition to the seat structure, affecting not only safety but also the correct operation of diagnostic systems – a properly selected and installed module eliminates airbag errors on the dashboard.

Benefits of using an original seat airbag

Using an original seat airbag in a Mercedes brings a number of practical benefits:

• preservation of the factory SRS system performance characteristics,
• proper fit to the seat structure and upholstery,
• consistency with the vehicle's electrical wiring and connectors,
• reduced risk of communication issues with the airbag control unit.

Thanks to this, the installation process is orderly, and the passive safety of the vehicle is restored to the parameters specified by the manufacturer.
