Technical and functional characteristics

The steering wheel multifunction buttons in this model are designed as an integral part of the control system in Mercedes R172 series vehicles. The OEM-based construction guarantees proper cooperation with the vehicle's factory electronics, including modules responsible for operating onboard systems. The button layout allows for intuitive control of functions without the need to reach for the center console.

The black, neutral color scheme makes it easy to aesthetically match the original steering wheel, without the visual effect of an "add-on" or mismatched element. As a result, replacing a damaged button module does not negatively affect the stylistic consistency of the cockpit.

The original design solution ensures:

• correct positioning of the buttons relative to the driver's hands,
• stable mounting within the steering wheel structure,
• compatibility with factory electrical installation connectors.
