How do I maximize fuel efficiency in my Audi A3?

I recently bought an Audi A3 and I want to make sure I am getting the most out of my fuel. What steps can I take to maximize fuel efficiency?

First, make sure your tires are properly inflated. This can greatly impact your fuel efficiency. Also, avoid rapid acceleration and maintain a steady speed on the highways. Keeping an eye on your engine's air filter and getting regular tune-ups can also help improve fuel efficiency.
