How do you check the engine oil level in an Audi A4?

I just got my first Audi A4 and I want to make sure I properly maintain it. Can you give me some guidance on how to check the engine oil level and what to do if it's low?

To check the engine oil level in your Audi A4, start by locating the oil dipstick near the engine. Pull it out and wipe it clean with a cloth. Then reinsert it and pull it out again to see where the oil level falls on the dipstick. If it's below the minimum mark, you'll need to add more oil. It's recommended to use the manufacturer's recommended oil type and to only add small amounts at a time.
