What does the 'Eco' button in a Kia Sportage do?

I noticed there is an 'Eco' button on the dashboard of my Kia Sportage. What does it do exactly and when should I use it?

The 'Eco' button optimizes the engine and transmission settings for optimal fuel efficiency. It should be used during regular city driving or when stuck in traffic.

The 'Eco' button limits the power output of the air conditioning and other electrical components to conserve fuel. It's best to turn it off when driving on the highway or when you need full power and acceleration.

In my experience, the 'Eco' button can make a noticeable difference in fuel consumption, especially in congested urban areas. Just make sure to turn it off when you need maximum power.
