How can I check the engine oil level on an Audi A5?

I am worried that the oil level in my Audi A5 may be low. How can I check it and what should I do if it is low?

To check the engine oil level on an Audi A5, park the car on a flat surface and wait for the engine to cool down. Then, locate the dipstick and remove it from the engine. The oil level should be between the minimum and maximum marks on the dipstick. If it is low, add the recommended type of oil to bring it to the proper level.
