What does the exclamation mark in a circle on the car dashboard indicate?

The exclamation mark in a circle on the car dashboard is the brake warning light. If the light is on (red), it means the car has issued a brake warning. Under normal circumstances, if the red brake warning light comes on, the ABS warning light will also illuminate. This is because, under normal conditions, if there is a fault in the braking system, the ABS will also be affected. The reasons for the exclamation mark in a circle lighting up include: the parking brake is not tightened, the brake fluid level is too low, or the brake pads have worn to their limit. When this light comes on, first tighten the parking brake. If it still remains on, add some brake fluid. If the light persists after adding brake fluid, it indicates a brake pad wear issue, and the brake pads need to be replaced. There are two other types of warning lights on a car: an exclamation mark inside parentheses and a triangle with an exclamation mark. If the exclamation mark inside parentheses lights up, it indicates an issue with the tire pressure of a certain tire, which needs to be checked promptly. If the triangle with an exclamation mark lights up, it could indicate an intervention or fault in the fuel cutoff system, a fault in the engine oil pressure sensor, an issue with external lights or parking sensors, or overheating of the clutch in a dry dual-clutch transmission.
