How can I optimize fuel efficiency in my Kia Sorento?

I have noticed that my Kia Sorento's fuel efficiency is not as good as it used to be. What steps can I take to improve it?

Regularly check and replace air filters to improve airflow and combustion in the engine.

Stick to the recommended tire pressure to reduce rolling resistance and improve fuel efficiency.

Avoid sudden acceleration and braking, as it can waste fuel.

Consider using cruise control on long drives, as it can help maintain a consistent speed and save fuel.
