How do I check the fluid levels in an Audi A2?

I recently purchased an Audi A2 and I want to make sure I am properly maintaining it. Can someone explain to me how to check the fluid levels in the car?

To check the fluid levels in your Audi A2, start by locating the engine oil dipstick. Make sure the car is on a flat surface and the engine is cold before removing the dipstick and wiping it clean. Then, insert it back into the tube and remove it again to check the oil level. If the level is below the minimum mark, add more oil. You can also check the levels of other fluids such as coolant, brake fluid, and transmission fluid in a similar manner.
