How do I improve my Kia Soul's fuel economy?

I recently purchased a Kia Soul and I've noticed that it's not getting the fuel efficiency that I expected. What steps can I take to improve its fuel economy?

Regularly check and replace your air filter to improve air flow and optimize fuel efficiency.

Maintain proper tire pressure to reduce resistance and increase gas mileage.

Avoid aggressive driving habits such as quick acceleration and braking, as this can waste fuel.
