What does a red exclamation mark in the car mean?

[VanKendra]

A red exclamation mark appearing 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 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. Braking System Fault: An exclamation mark inside a circle with parentheses. 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. Tire Pressure Abnormality: An exclamation mark with a horizontal line under parentheses. 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. 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. For example, 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. Replace the transmission oil promptly. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a fault in a car light. Solution: Go to a 4S shop for inspection and treatment 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. Red indicates a very serious problem in the corresponding system. If this occurs, 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 illuminate, and the system will perform an automatic check. After the check is completed, the lights will automatically turn off. If a light does not illuminate when the ignition is turned on, stays on continuously, 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.
