What does the exclamation mark warning light in Changan vehicles mean?
2 Answers
When an exclamation mark appears on the car dashboard, there are 5 possible situations: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these 5 situations: General malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components or functions. Possible causes include parking sensor failure, fuel cutoff system intervention or malfunction, exterior light failure, or engine oil pressure sensor failure. 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 transmission failure or transmission fluid level below normal range. Transmission fluid should be replaced promptly. Brake system failure: An exclamation mark inside a circled parenthesis represents a brake system warning, mainly indicating brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal tire pressure: An exclamation mark below a horizontal line inside a parenthesis is the tire pressure monitoring warning light, which illuminates when 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 failure indicator, signaling a malfunction in vehicle lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct self-inspection focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem.
When the exclamation mark warning light comes on in my Changan car, I always get nervous immediately because, as a frequent driver, I know it could indicate various issues. Common causes include brake system warnings, such as low brake fluid levels or braking problems; low tire pressure can also trigger it, as the system lights up when it detects insufficient pressure. Other possibilities include engine faults or battery issues. As soon as the light turns on, I recommend slowing down and pulling over to check the dashboard for specific indicators—for example, if the tire pressure shows an anomaly, try inflating the tires promptly. If you can't resolve it yourself, you must visit a 4S shop or professional repair center as soon as possible. This light is directly related to driving safety, especially on highways or at night—ignoring it could lead to accidents. That's why I often make a habit of checking all warning lights before driving to avoid trouble on the road. Regular maintenance is truly important, and during every service, I ask the technician to thoroughly inspect these critical components.
