What does the exclamation mark light on the car mean?

[StKeegan]

There are five situations when an exclamation mark appears on the car dashboard: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. The following is a detailed analysis of the five situations: General faults: An exclamation mark inside a triangle indicates that the car's general performance or components and functions have malfunctioned. Main faults 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 faults: 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 faults: An exclamation mark inside a circle with parentheses represents a warning for the brake system, mainly indicating brake system failure 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 under parentheses represents the tire pressure monitoring warning light. This light will turn on when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting faults: A yellow bulb with an exclamation mark is the lighting fault indicator light, indicating that a car light has malfunctioned. Solution: Go to a 4S shop for inspection and repair as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lights to see where the problem lies.
