There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting system fault. Below is a detailed analysis of these five situations: General Malfunction: An exclamation mark inside a triangle indicates a fault in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It's necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission fault or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Failure: An exclamation mark inside a circled parenthesis represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to prevent accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line underneath a parenthesis is the tire pressure monitoring warning light. It illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Don't ignore the exclamation mark on your dashboard! I've encountered this several times, with different shapes indicating different issues. The most common is an exclamation mark inside a circle, which is the brake warning light. It could mean the handbrake isn't fully released, the brake fluid is low, or the brake pads are worn out. If it's an exclamation mark inside parentheses, it's likely a tire pressure issue, maybe a punctured tire losing air. A triangle with an exclamation mark in the middle usually indicates a problem with the vehicle's electronic stability system. I've also seen an exclamation mark with wavy lines, which means the coolant temperature is too high. And when the power steering fails, the steering wheel suddenly becomes very heavy, and an exclamation mark will light up. If you see a red light, stop immediately and check. Don't push your luck with a yellow light either—get to a repair shop as soon as possible.

After driving for a long time, you'll realize that the small exclamation mark on the dashboard is actually quite complex. There are mainly three types: a circle with an exclamation mark indicates a brake system issue, possibly the electronic parking brake not being released or insufficient hydraulic pressure; a parenthesis with an exclamation mark specifically monitors tire pressure, alerting you to abnormal tire pressure; a triangle with an exclamation mark is more general, possibly indicating a warning for the airbag or electronic stability control system. Don't panic when you see this light on—pull over safely and first check the basics: whether the parking brake is fully released and if any tires are noticeably flat. If everything seems normal but the light remains on, don't hesitate to contact a repair shop immediately. Remember to regularly check brake fluid levels and tire wear during maintenance to prevent many issues.

The exclamation mark warning light in the car can indicate issues ranging from minor to serious. The circle-shaped one usually signals brake problems, and it's recommended to slow down and pull over immediately. The parentheses-shaped light indicates tire pressure warning, meaning it's time to inflate the tires. The triangle-shaped light generally alerts to safety system malfunctions. I keep an air pump in my car, so I can handle tire pressure warnings myself. But if the brake light comes on, you must stop immediately to check the handbrake position and brake pedal feel. In complex situations, it's best not to continue driving and instead have the car towed to a professional repair shop. Regularly checking tire pressure and brake fluid monthly can prevent most issues.
