What does an exclamation mark in a vehicle mean?

[DiJaxson]

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 that feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed explanation of 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 vehicle's general performance or components and functions. Main 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 fault in the transmission or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Brake system fault: An exclamation mark inside a circle with parentheses. 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: An exclamation mark with a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the vehicle's tire pressure is too low. Check the vehicle'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, indicating a fault in the vehicle's lights. Solution: Visit 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 a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest 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. Pull over immediately and call for professional assistance 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 turn off automatically. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for vehicle inspection to eliminate safety hazards.
