Purpose and function of the ASR OFF button

The ASR OFF button is dedicated to Mercedes W638 and W901–W905 series vehicles, where it is responsible for controlling the drive wheel anti-slip system. Its task is to send a signal to the controller to temporarily deactivate traction control, which can be beneficial, for example, when starting on loose, slippery surfaces, mud, or snow. This allows the driver to consciously adapt the vehicle's behavior to current conditions, maintaining greater driving flexibility.

Design and cockpit integration

The component is designed as part of the interior control panel, featuring an ergonomic button with clear function labeling. The manufacturer's design ensures a perfect fit for the factory slot in the dashboard, facilitating installation and maintaining a consistent interior look. Original manufacturing ensures proper cooperation with the electrical system and other control modules in the vehicle.

Benefits of using an original Mercedes component

Using a factory ASR OFF button in Mercedes vehicles translates into:

• reliable compatibility with the electrical system and onboard electronics,
• consistent fit with the center console and other switches,
• preservation of the ASR system functionality as intended by the manufacturer,
• easier diagnostics in the event of potential traction system faults.

For fleet users and workshops specializing in the Mercedes brand, this is a solution that allows maintaining the vehicle in a configuration close to the factory state, without the need to use replacements with uncertain parameters.

Condition, service application, and operational aspects

The offered component comes from the Pedals, pedal pads, and footrests group, which means it is part of the broadly defined driver control zone. The used product will work well both as a service part for routine repairs and for restoring full cabin functionality after mechanical damage or interference with the installation. Replacing the button is usually a straightforward task for an experienced mechanic or auto electrician, which minimizes vehicle downtime.
