What does the triangular exclamation mark symbol on the car display mean?

[LaKevin]

The triangular exclamation mark symbol on the car display refers to the general fault indicator light. The reasons for its illumination are: 1. Overheating of the dry dual-clutch transmission clutch; 2. Intervention or malfunction of the fuel cut-off system; 3. Issues with the parking sensors; 4. Abnormal external light circuit; 5. Malfunction of the engine oil pressure sensor; 6. Warning or fault in the traction control system. Other fault indicators on the car display include: 1. A yellow exclamation mark inside parentheses: This is the tire pressure monitoring indicator, which lights up when the tire pressure is insufficient; 2. A yellow exclamation mark inside a gear: This is the automatic transmission fault warning light, which indicates a fault in the transmission, transmission lubricant below the normal range, or the need for lubricant replacement.

I've been driving for over a decade, and when that triangular warning light with an exclamation mark pops up on the dashboard, I know it's not a minor issue. This yellow triangle is the master system alert—it could mean low brake fluid, insufficient tire pressure, or a burnt-out bulb. Last time it lit up while I was on the highway, it gave me quite a scare, so I immediately slowed down and pulled over. The first thing I did was check the dashboard for any other warning lights, like the ABS or airbag indicators flashing simultaneously, which would indicate a more serious problem. Then, I got out to inspect the tire pressure and feel the brake pads' temperature. If everything seemed fine, I'd check the trouble codes. Never take it lightly—safety always comes first.

As a young car owner, this triangle exclamation mark is often discussed in our car enthusiast group. It's like a system inspector, alerting you to something abnormal. My advice is not to panic immediately—first, check if there's any text prompt on the central display screen. Modern cars can display specific issues, such as reminders to replace brake pads or low battery warnings. If there's no text, press the menu button on the steering wheel to enter engineering mode and check the error codes; the owner's manual includes a fault code table. Last time my warning light came on was during rainy weather when the radar got dirty—wiping it clean made the light disappear. In short, don't push your luck; get it fixed when needed.

That day while picking up my child from school, I suddenly noticed a triangular exclamation mark appear on the dashboard. I immediately reduced speed, pulled over, and turned on the hazard lights. After checking the manual, I learned this is called the comprehensive warning light—it could be as simple as the trunk not being fully closed or as serious as an engine malfunction. First, I checked if all doors were locked, then looked at the fuel gauge, and finally realized it was just a maintenance countdown reminder. I recommend all female drivers keep a manual in the glove compartment. If you encounter this situation, don't randomly press buttons—just go straight to the 4S dealership for a computer diagnostic check, that's the safest approach.
