What does it mean when the car displays 'STOP'?

[StevenRose]

When a car displays 'STOP', it indicates a mandatory stop alarm. In such cases, the engine operation should be stopped immediately. The main reasons for this alarm light to illuminate include low oil pressure, low brake fluid level, or high coolant temperature. The mandatory stop alarm light is connected to the engine oil pressure, brake fluid level, coolant temperature gauge, and electronic brake force distribution system. It is not an independent warning light. After this warning light comes on, other corresponding components of the car should be checked. It's important to note that this alarm light usually comes in two colors: yellow represents a general fault, while red indicates a serious fault.
