What does it mean when a warning light with an exclamation mark inside a circle appears on the car dashboard?

The appearance of a warning light with an exclamation mark inside a circle on the car dashboard indicates the brake warning light. Possible issues with the braking system include: 1. Severe wear of the brake friction pads; 2. Low brake fluid level; 3. The parking brake is engaged; 4. If it is a red brake warning light, the ABS warning light may also illuminate simultaneously, as the ABS cannot function properly when there is a fault in the conventional braking system. The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicator lights include: battery indicator, fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators.

A few days ago, the warning light with an exclamation mark inside a circle suddenly appeared on the dashboard of my old car, which gave me a scare. Based on experience, this is most likely an abnormality in the braking system—possibly the handbrake wasn’t fully released or the brake fluid was running low. I remember last winter when this light came on while driving, I overlooked it, and the brakes felt a bit soft, almost causing an accident. I immediately pulled over to check the fluid level and found it was dangerously low. After topping up the brake fluid, the light went off. The braking system is crucial for safe driving, so it’s important to regularly inspect the antifreeze reservoir and sensor wiring, replacing any aged parts promptly. My advice is to first stop and confirm if the handbrake is properly engaged, then check the brake fluid reservoir level in the engine bay—if it’s below the marked line, top it up or seek repairs. Don’t risk continuing to drive like I did back then; find a reliable mechanic to fix it properly as soon as possible.

Bro, you're asking about that dashboard warning light with a circle and an exclamation mark? Most likely it's a brake system issue, super common. First check if the handbrake is fully released; if the light stays on after releasing it, pop the hood and check whether the brake fluid level is between MIN and MAX marks. Don't risk driving if the problem persists - it could cause skidding accidents. Just call a tow truck or drive carefully to the nearest repair shop. It could be triggered by sensor malfunction or brake fluid leakage - too complicated for DIY diagnosis. Stay calm and prioritize safety - last time I handled it this way, the problem got fixed immediately.

The circle exclamation light on the dashboard primarily indicates a brake system warning. It may be caused by issues such as the parking brake not being fully released, insufficient brake fluid, or severely worn brake pads. The brake fluid reservoir is typically a transparent container under the hood—check if the fluid level is below the marked line. If the fluid level is normal, inspect whether the sensor has poor contact. If the problem persists after simple self-checks, a mechanic should diagnose it with professional equipment to avoid hazards while driving. Regular vehicle maintenance can help prevent such issues.
