How do I maintain the fuel efficiency of my Kia Sorento?

I recently purchased a Kia Sorento and I want to make sure I am taking all the necessary steps to keep it running smoothly. Any tips on how to maintain its fuel efficiency?

Regularly check and replace your air filter to ensure proper air flow and engine performance. This can greatly affect your fuel efficiency.

Make sure your tires are properly inflated. Low tire pressure can lead to decreased fuel efficiency.

Avoid accelerating or braking harshly. This not only causes wear and tear on your vehicle, but also decreases fuel efficiency.
