How to improve the fuel economy on an Audi A2?

I recently purchased an Audi A2 and I'm looking for ways to improve its fuel economy. Any tips or suggestions?

First, make sure your tires are properly inflated. Underinflated tires can decrease fuel efficiency. Also, try to avoid idling for extended periods of time.

Another thing you can do is avoid heavy acceleration and braking. These actions can waste fuel. Instead, try to maintain a steady speed while driving.
