What Does the Exclamation Mark Warning Light in a Car Mean?
1 Answers
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 general performance or component malfunction. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is recommended to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark is the automatic transmission warning light, indicating a transmission fault or low transmission fluid level. The transmission fluid should be replaced promptly. Brake System Failure: An exclamation mark inside a circle with parentheses represents a brake system warning, typically signaling brake system malfunction or low brake fluid level. Immediate inspection of the brake system is necessary to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below parentheses 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 Failure: A yellow bulb with an exclamation mark is the lighting failure indicator, signaling a malfunction in the vehicle's lighting system. Solution: Visit a 4S shop for inspection as soon as possible. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
