What does the Eco button on my Kia Rio do?

I have noticed an Eco button on my Kia Rio dashboard. What does it do and should I use it?

The Eco button on your Kia Rio adjusts the car's engine, transmission, and air conditioning performance to maximize fuel efficiency. It can be useful to use when driving in stop-and-go traffic or on long trips to save gas.

Using the Eco button may result in a slight decrease in engine power and acceleration. If you are looking for a sporty and powerful driving experience, it is best not to use the Eco button.

I have found that using the Eco button on my Kia Rio has saved me money on gas. It also helps reduce emissions, which is better for the environment.
