What does the yellow exclamation mark in a vehicle mean?

[MorganFitz]

There are three situations when a yellow exclamation mark appears in a vehicle: 1. A yellow triangle with an exclamation mark in the middle, this indicator is the traction control system light, which reminds the owner to turn off the traction control system when it lights up; 2. A yellow gear with an exclamation mark in the middle, this 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, and the transmission needs to be checked and the lubricant replaced; 3. A yellow bracket with an exclamation mark in the middle, this is the tire pressure monitoring indicator, indicating that the pressure of a certain tire is insufficient, and the tire pressure should be checked at a tire shop or 4S store. When an indicator light with an exclamation mark on the dashboard lights up, it usually means that the corresponding component has an abnormality or fault, and the owner should find the source of the fault as soon as possible to avoid further expansion of the fault impact.
