Why Does the Exclamation Mark Appear on the Car Dashboard?

[DiAndrew]

There are five possible reasons for an exclamation mark appearing on the car dashboard: general faults, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting failure. Below is a detailed analysis of these five scenarios: General Faults: A triangle with an exclamation mark indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off 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 Failure: A yellow gear with an exclamation mark is the automatic transmission fault warning light, indicating a problem with the transmission or low transmission fluid. The transmission fluid should be replaced promptly. Brake System Failure: A circle with parentheses and an exclamation mark in the middle represents a brake system warning. Common causes include brake system malfunction and low brake fluid levels. Immediate inspection and repair of the brake system are required to avoid accidents. Abnormal Tire Pressure: A horizontal line with parentheses and an exclamation mark below it indicates the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Failure: 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 as soon as possible for inspection and repair, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
