What does the exclamation mark symbol in the car mean?

[StBella]

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault 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 Fault: A yellow gear with an exclamation mark inside. This 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 Fault: A circle with parentheses and an exclamation mark in the middle. This represents a brake system warning, primarily indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to prevent accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below parentheses. This represents 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 Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, signaling a malfunction in the car's lights. Solution: Visit a 4S shop for inspection 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 issue. Additionally, during daily vehicle use, the fault lights displayed on the dashboard are categorized into two colors: yellow and red, indicating different levels of severity: Yellow indicates a fault in the corresponding system that is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious issue in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate as the system performs an automatic check. After the check is completed, the lights will turn off automatically. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such situations, seek professional help promptly to inspect and resolve the issue to ensure safety.
