What does the 'Eco' button do in the Kia Sorento?

I've noticed a button labeled 'Eco' in my Kia Sorento and I'm not sure what it does. Can someone explain its function and if it's worth using?

The 'Eco' button is designed to help improve the fuel efficiency of your Kia Sorento. When activated, it adjusts the engine's performance and limits energy consumption, which can lead to better gas mileage. However, it may also cause the car to feel less responsive and decrease acceleration.

I personally don't use the 'Eco' button because I don't notice a significant difference in fuel efficiency and it does make the car feel sluggish. However, if you're someone who prioritizes gas mileage over performance, it may be worth using.

As someone who has used the 'Eco' button regularly, I've found that it does make a noticeable difference in fuel efficiency, especially on longer trips. I would recommend trying it out and see if it works for you.
