What does the exclamation mark on the car steering wheel mean?

[DelBriella]

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, braking system fault light, transmission fault indicator light, and wiper fault indicator light. The following 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 malfunction, external light failure, engine oil pressure sensor failure, etc. Solution: It is necessary to go to a 4S shop for inspection, where professionals can 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. Solution: The transmission oil needs to be replaced in time. Although it can be replaced independently, it is not recommended to do so. It is still necessary for professionals to replace different transmission oils according to different cars. 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. Solution: First, check if the handbrake is released. If the fault light still displays after releasing it, you need to drive slowly to a repair shop for professional inspection. Abnormal tire pressure: 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 light up. Solution: If you have a tire pressure detector, you can check it yourself. If not, you need to go to a 4S shop for inspection and restore the tire pressure 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 and treatment as soon as possible. You can also check it 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 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. You need to slow down and drive 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. You should pull over 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 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 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 for car inspection and elimination of potential safety hazards.
