What Causes the Exclamation Mark to Appear When Starting a Car?
1 Answers
There are five possible scenarios when an exclamation mark appears on the car dashboard: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Faults: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission fluid should be replaced promptly. Brake System Faults: An exclamation mark inside a circled parenthesis represents a brake system warning, primarily indicating brake system failure or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a parenthesis is the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Faults: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem.
