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 warning 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 failure, fuel cut-off 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 that there is a fault in the transmission or the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal tire pressure: A horizontal line with parentheses and an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. 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 that a car light has failed. Solution: Go to a 4S shop for inspection as soon as possible, or check it 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 warning lights displayed on the vehicle dashboard are divided into two different colors: yellow and red: Yellow indicates that there is 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 that there is a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately 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 started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will automatically turn off. If a light does not turn on when the ignition switch is turned on, remains on without turning off, or 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.
