What does the yellow exclamation mark light on the car mean?

[LeBlakely]

The appearance of a yellow exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, braking system fault light, transmission fault indicator light, and wiper fault indicator light. Below is a detailed introduction to the exclamation mark fault 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. Main issues include parking sensor failure, fuel cutoff system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to 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 fault in the transmission or transmission lubricant below the normal range. The transmission oil needs to be replaced promptly. Braking System Fault: An exclamation mark inside a circle with brackets. This represents a warning for the braking system, mainly indicating a fault in the braking system or low brake fluid level. The braking system should be inspected immediately to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line under brackets. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. Check the car's 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, indicating a fault in the car lights. Solution: Go to a 4S shop for inspection as soon as possible, or check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the vehicle dashboard are divided into two different colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the corresponding repair point for maintenance to eliminate potential safety hazards in time. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Stop the car by the roadside in time and call for professional help to prevent unpredictable dangers to the vehicle and personal safety from forced driving. It should be noted that when the car is ignited and started, all lights will light up, and the system will perform an automatic detection. After the detection is completed, the lights will automatically turn off. If a light does not light up when the ignition switch is turned on, or remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help in time for car inspection to eliminate potential safety hazards.
