The phrase refers to a notification, often appearing in a vehicle’s instrument cluster, indicating a malfunction or issue within the system responsible for maintaining optimal grip and stability during acceleration, braking, or cornering. This system typically manages wheel spin by selectively applying brakes to individual wheels or reducing engine power, thereby enhancing vehicle control, especially on slippery surfaces. Illumination of this warning signals a problem that may compromise the vehicle’s ability to maintain adequate grip.
Addressing the underlying cause promptly is vital for preserving driver safety and preventing further damage. This system is a crucial safety feature, aiding in preventing loss of control scenarios. Its development represents a significant advancement in automotive engineering, building upon earlier anti-lock braking systems to provide a more comprehensive approach to stability management. Neglecting this warning can increase the risk of accidents, particularly in adverse driving conditions.
