What does an exclamation mark in a circle mean?

Red exclamation mark (specifically in the form of an exclamation mark inside a circle), this represents a warning for the braking system, mainly indicating a malfunction in the braking system or low brake fluid level. Solution: Immediate inspection and repair of the braking system are required to avoid accidents. Apart from the red exclamation mark indicating braking system issues, all other exclamation marks on a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four scenarios: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. This mainly includes parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a bracket. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
I encountered the same situation while driving the other day when a circle with an exclamation mark suddenly appeared on the dashboard. This is actually a warning light indicating that the handbrake is not fully released, especially common in German cars like Volkswagen and Audi. If you drive without releasing the handbrake, not only will the light come on, but some cars also emit a beeping alarm sound. However, it could also indicate an issue with the braking system, such as low brake fluid or an ABS malfunction. Last time I saw this, I first checked the handbrake lever and found it was stuck halfway. After ruling out this possibility, it's best to immediately visit a repair shop to scan for fault codes. Don’t continue driving like some careless owners, as it can wear out the brake pads or even lead to brake failure. Safety is no small matter—never ignore this warning light.
After driving for ten years, I've figured out all kinds of dashboard warning lights. That circle with an exclamation mark mainly indicates three situations: The simplest is when the handbrake isn't fully released - just pull and release the handbrake lever again to fix it. More commonly, it signals insufficient brake fluid - pop the hood, locate the brake fluid reservoir, and top it up if the level is below the MIN mark. The most troublesome case is electronic system failure, like when a wheel speed sensor goes bad and triggers this warning. Don't panic when you see it - try pulling over and restarting the vehicle, as sometimes it's just a computer glitch. Last month, my neighbor ignored this light and nearly had an accident on the highway when the brakes stiffened. I recommend keeping brake fluid in your car, but if the light stays on persistently, you must seek professional repair.
This is the sign that beginners most often get confused about. Let me teach you a three-step troubleshooting method: first, check if the handbrake is fully released; next, inspect the brake fluid reservoir level; finally, test if the brake pedal feels unusually hard. Many car manuals print an illustration of this warning light – finding and comparing it is the safest approach. Don't believe online claims about diagnosing by kicking tires – last time my friend's car actually had leaking brake fluid lines, completely invisible to the naked eye. If the brake pedal softens or makes abnormal noises when this light is on, call for a tow truck immediately – never continue driving. This warning light is no joke – it directly relates to braking system safety.
