What does a triangle exclamation mark on the car dashboard mean?
2 Answers
A triangle exclamation mark on the car dashboard indicates a general fault in the vehicle. Common faults include overheating of the dry dual-clutch transmission, intervention or malfunction of the fuel cutoff system, parking sensor failure, exterior bulb failure, engine oil pressure sensor failure, traction control system warning or malfunction, etc. These faults generally refer to routine issues with the car. Whenever any of these faults occur, the triangle exclamation mark light on the dashboard will illuminate. In addition to the triangle exclamation mark indicator, other dashboard indicators with an exclamation mark include the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Whenever any warning light with an exclamation mark lights up, it indicates a problem with the corresponding part of the car, and it should be inspected and repaired promptly.
That day I was just driving on the highway for a long distance when suddenly a yellow triangle with an exclamation mark popped up on the dashboard, and my heart skipped a beat. Later, I checked the owner's manual and learned that this is called the comprehensive warning light, like the car's health monitor. The most common issue is tire-related, like when I encountered low tire pressure last time; it could also be a lighting fault, such as a burnt-out taillight. Minor things like a door not being closed properly or insufficient windshield washer fluid can also trigger it. Here's a tip: check if there's a text prompt on the central control screen—my car, for example, shows which specific door isn't closed. If the light stays on after restarting, it's best to first check all four tires. If there's no issue, then drive to a repair shop to read the fault codes. Never ignore it, as it could be dangerous if it's really a brake system failure.
