What does a yellow exclamation mark on the car mean?

[VonHarmony]

There is a yellow exclamation mark on the car: 1. A bracket with an exclamation mark in the middle and a pattern line at the bottom. When the light is on, it indicates that the vehicle's tire is underinflated; 2. A steering wheel pattern on the left and an exclamation mark on the right. This light comes in red and yellow. When the yellow light is on, it means there is a fault in the steering system, but the vehicle can still be driven; when the red light is on, the power steering will fail, and immediate repair is required. 3. A red circle with an exclamation mark in the middle and a pair of brackets outside the circle, which may indicate brake system oil leakage or severely worn brake pads; 4. A triangle with an exclamation mark inside, which is called a multifunction warning light and will illuminate along with other fault lights.
