How can I make sure that my Volkswagen T-Cross stays fuel efficient?

I just bought a brand new Volkswagen T-Cross and I want to make sure that it stays fuel efficient for as long as possible. Do you have any tips or suggestions on how I can achieve this? I'm not very knowledgeable about cars, so any advice would be greatly appreciated.

Regularly checking and replacing your air filter can improve fuel efficiency.

Avoiding aggressive driving and heavy acceleration can also help maintain fuel efficiency.

Make sure to keep your tires properly inflated to maximize fuel efficiency.
