How can I improve my gas mileage on my Audi A2?

I've noticed that my Audi A2 doesn't get as good gas mileage as it used to. What can I do to improve its efficiency?

One useful way to improve gas mileage is by maintaining proper tire pressure. This can increase fuel efficiency by up to 3%.

Another helpful tip is to avoid idling for extended periods of time, as this can waste fuel. Consider turning off the engine if you know you'll be parked for more than a minute.
