Why is there an exclamation mark on the car display?
2 Answers
There are five possible situations when an exclamation mark appears on the car dashboard: general fault, automatic transmission fault, brake system fault, abnormal tire pressure, and lighting fault. The following is a detailed analysis of these five situations: General Fault: An exclamation mark inside a triangle indicates a general performance or component and function fault in the car. It mainly includes 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 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 needs to be replaced in time. Brake System Fault: An exclamation mark in the middle of a circle with brackets represents a warning of the brake system, mainly indicating a brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal Tire Pressure: An exclamation mark in the middle of a line under brackets represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will light up. It is necessary to check the tire pressure of the car and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator light, indicating that there is a fault in the car lights. Solution: Go to the 4S shop for inspection and treatment as soon as possible, or you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to see where the problem is.
The exclamation mark warning icon on the car display usually indicates a problem with the vehicle that requires your attention. The most common alert is the low tire pressure system warning, which shows a yellow exclamation mark with a tire symbol, indicating that one of the tires is underinflated and needs air. If the exclamation mark is red, it may represent a more serious issue, such as brake system failure or low engine oil pressure. Other possible causes include an unsecured door, a faulty door sensor, an anti-lock braking system (ABS) malfunction, or abnormal battery charging. Essentially, this icon is a warning signal triggered by the vehicle's electronic control unit (ECU) when it detects abnormal data, aiming to prevent driving risks. When this icon appears, you should stop to check the tire pressure or look for additional text instructions on the dashboard. If the issue persists, it is advisable to visit a professional repair shop immediately for inspection and resolution—safety always comes first.
