The document explains the Mercedes ESP warning light, detailing two scenarios: a flashing light indicates the electronic stability program (ESP) is actively stabilizing the vehicle in response to traction loss, while a persistent light suggests potential malfunctions in the ESP system. It emphasizes the importance of maintaining the ESP for safe vehicle operation and advises checking for issues like sensor problems or low brake fluid if the light remains on. The conclusion reinforces that a flashing light on slippery surfaces is normal but encourages professional checks for persistent warnings.
