How to properly maintain the fuel efficiency in a Kia ProCeed?

I recently bought a Kia ProCeed and I've noticed the fuel efficiency isn't as good as I expected. What can I do to keep it in top shape and maintain good fuel efficiency?

Regularly check and replace air filters. Dirty air filters can restrict airflow and cause your car to burn more fuel. It is recommended to replace them every 12,000-15,000 miles.

Make sure your tires are properly inflated. Under-inflated tires can increase fuel consumption by 3-4%. Check your tire pressure once a month and before long trips.

Avoid sudden accelerations and hard braking. This can burn up to 40% more fuel! Try to maintain a steady and moderate speed while driving.

Regularly service your car. A well-maintained car can save you up to 10% on fuel consumption. Make sure to follow the manufacturer's recommended service schedule.
