How do I check my oil levels in my Audi A6?

I need to know how to properly check the oil levels in my Audi A6. Can someone provide a step-by-step guide?

To check your Audi A6's oil levels, follow these simple steps: 1. Park your car on a level surface and wait for the engine to cool down. 2. Pop open the hood and locate the oil dipstick. 3. Pull out the dipstick and wipe it clean with a cloth. 4. Re-insert the dipstick and pull it out again. The oil level should be between the two marks on the dipstick. If it's below the bottom mark, add more oil. If it's above the top mark, have the oil drained.
