What does the yellow exclamation mark on the car dashboard indicate?

[StellaRose]

The appearance of an exclamation mark on the car dashboard indicates a malfunction in the vehicle's internal components, signaling an abnormality or fault in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, and transmission fault indicator. Below is a detailed explanation of the various exclamation mark warning lights: Automatic Transmission Fault: A yellow gear with an exclamation mark inside represents the automatic transmission fault warning light, indicating a fault in the transmission or transmission fluid levels below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses signifies a brake system warning, primarily indicating a brake system malfunction or low brake fluid levels. Immediate inspection and repair of the brake system are necessary to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below parentheses represents the tire pressure monitoring warning light. This light illuminates when the 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 indicates a lighting fault warning light, signaling a malfunction in the vehicle's lights. Visit a 4S shop for inspection or check the commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. General Fault: An exclamation mark inside a triangle indicates a general performance or component fault, including parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. Visit a 4S shop for diagnosis and repair. Additionally, during daily vehicle use, the warning lights on the dashboard are categorized into yellow and red, indicating different levels of severity: Yellow indicates a fault in the corresponding system that is not critical. Reduce speed and proceed to a repair facility to eliminate potential hazards. Red indicates a severe issue in the corresponding system. In such cases, do not continue driving. Pull over safely and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note: When starting the car, all warning lights will illuminate as the system performs an automatic check. They should turn off after the check is complete. 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. Seek professional help immediately to inspect and resolve the issue.
