Vehicle Application and Function

The presented knee airbag is a passive safety system component installed in the front cabin area, on the driver’s side. It operates in an integrated system with other airbags and the SRS control unit, limiting the forces acting on the legs and knees during a front impact.

The vehicle placement specified as front driver’s side means the component is intended for installation in the lower part of the dashboard, directly in front of the driver’s knees. This ensures the correct deployment zone for the airbag and compatibility with factory trim panels.

Compatibility and Fitment for Mercedes W177 / C118

The airbag has been developed for the platform used in the Mercedes A-Class W177 and the CLA C118 model, guaranteeing a proper fit for the dashboard structure of these generations. This means:

• compliance with factory mounting points within the dashboard structure,
• correct positioning relative to the steering column and driver’s seat,
• operation with the original airbag system control unit.

This ensures a streamlined installation process without the need for interior structure modifications. Original Mercedes origin promotes consistency within the entire safety system and minimizes the risk of installation errors.

Characteristics of a Used Component

The knee airbag is a salvaged part, allowing for an economical repair of the SRS system while retaining an OEM component. As a used item, it should be inspected by a qualified service center before reinstallation to verify:

• that the pyrotechnic charge has not been previously deployed,
• the condition of electrical connectors and wiring harness,
• the integrity of the housing and mounting points.

This approach allows for the safe restoration of full airbag system functionality in the vehicle after a collision or dashboard replacement.

Benefits of Using an Original Knee Airbag

Utilizing a factory knee airbag in the Mercedes W177 / C118 offers several practical advantages:

• Full Dashboard Integration – maintaining correct mounting geometry and fit with interior elements.
• SRS System Consistency – proper interaction with collision sensors and the airbag control unit.
• Reduced Repair Costs – a used OEM part is an attractive alternative to new service parts.
• Predictable Performance in Case of Collision – construction compliant with the vehicle manufacturer’s specifications.

For workshops specializing in accident repairs and for individual owners, this means the ability to restore the factory level of protection in the driver’s knee area without compromising the vehicle’s structure.
