What does the exclamation mark on the Civic dashboard mean?

[VonMason]

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 failure. 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 when illuminated. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is 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 fault warning light, indicating a transmission malfunction 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 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 below a horizontal line inside a parenthesis is the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Failure: 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 lighting to identify the problem.

I just encountered this situation last week! The red circle with an exclamation mark usually means the handbrake isn't fully released or there's insufficient brake fluid - this is no joking matter. If it's a yellow triangle with an exclamation mark, it's most likely unstable tire pressure; pull over immediately to check your tires. My experience driving five Hondas tells me that the most annoying light in 10th-gen Civics is the electric power steering fault indicator (the steering wheel icon with an exclamation mark), when you'll noticeably feel the steering wheel become heavier. Never ignore any exclamation warnings - consulting the manual is always the safest bet. The manual has incredibly detailed icon explanations where you can find the corresponding trouble code in minutes. If a wrench icon flashes simultaneously on the dashboard, that just means it's maintenance time - no need to panic about that one.
