How can I improve my fuel efficiency in the Kia Sportage?

I recently purchased a Kia Sportage and I've noticed that I'm using a lot more gas than expected. What are some tips for improving my fuel efficiency?

Regularly maintain and service your vehicle. This includes changing the oil, replacing air filters, and getting tune-ups. Keeping your car in good shape can greatly improve fuel efficiency.

Avoid aggressive driving and heavy acceleration. This can use up a lot of gas and decrease your fuel efficiency.

Check your tire pressure regularly. Under-inflated tires can lower fuel efficiency.

Limit the use of your air conditioning. It can use up a lot of gas, especially at higher speeds.
