[LaConnor]

The appearance of an 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, brake system fault light, transmission fault indicator light, and wiper fault indicator light. Below is a detailed introduction to the exclamation mark fault lights: General faults: 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 faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, 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. Brake system fault: An exclamation mark inside a circle with brackets. This represents a warning for the brake system, mainly indicating a fault in the brake system or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure abnormality: An exclamation mark in the middle of a horizontal line with brackets below. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. The tire pressure should be checked and restored 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 the 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 immediately and call for professional help to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It should be noted that when the car is started, all lights will turn on, and the system will perform an automatic detection. After the detection is completed, the lights will automatically turn off. If a light does not turn on when the ignition is turned on, or if it stays on, or if it lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for car inspection to eliminate potential safety hazards.
