Intended Use and Compatibility

The presented steering wheel airbag has been designed for first-generation Ford S-MAX and fourth-generation Ford Mondeo models equipped with the factory SRS system. The component is installed on the driver's side, directly in the center of the steering wheel, ensuring proper placement of the pyrotechnic charge and appropriate inflation geometry relative to the driver's posture.

Original origin from the Ford group means preserved correct mounting points, housing shape, and electrical connectors, which facilitates installation and minimizes the risk of fitting issues with the steering column and wiring harness.

Construction and Function in the Safety System

The steering wheel airbag plays a crucial role in the passive safety system, cooperating with collision sensors, the SRS controller, and seatbelt pretensioners. A correctly selected component:

• ensures controlled inflation in the driver's axis,
• maintains appropriate housing rigidity and controlled fracture zones,
• remains compatible with the factory airbag controller.

Thanks to this, the safety system operates according to the vehicle manufacturer's specifications, and the risk of system errors (SRS warning light, malfunction messages) is limited with correct installation.

Condition, Origin, and Benefits of Using a Used Part

The component originates from the Ford group and is offered as a used part, representing a reasonable compromise between repair cost and maintaining original specifications. In practice, this means:

• factory fit for the steering wheel and column of the specific model,
• preservation of the original interior styling (shape, texture, embossing),
• possibility of economical repair of the airbag system after deployment.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to have the installation performed by a qualified service center, adhering to safety procedures when working with pyrotechnic systems.

Installation and Operational Guidelines

When replacing the steering wheel airbag in a Ford S-MAX MK1 or Mondeo MK4, it is worth paying attention to:

• disconnecting the vehicle's power supply and waiting the recommended time before starting work,
• checking the condition of the wiring harness, connectors, and the clock spring under the steering wheel,
• correctly tightening the fasteners according to the service procedure.

After installation, it is recommended to perform a computer diagnostic of the SRS system to confirm the absence of errors and proper communication between the controller and the newly installed component.
