While not necessarily indicating a problem, it's important to understand *why* it's off. It's usually deactivated manually by the driver via a button (often marked "TRAC OFF" or a similar symbol), but it could also illuminate due to a fault in the traction control system itself. If the light stays on consistently *without* you turning it off, you should have the car checked by a mechanic to diagnose any potential problems with the system's sensors, wiring, or other components.
