What does the Eco driving mode do?

I've noticed there is an Eco driving mode in my Kia Soul. Can anyone explain to me what it does and how it affects my driving experience?

The Eco driving mode adjusts the engine and transmission settings to prioritize fuel efficiency over performance. It can also adjust the air conditioning and throttle response to help save even more fuel.

Yes, I always use the Eco mode in my Kia Soul and it definitely helps with my gas mileage. It also makes the car feel a little less responsive, so I use it mostly for city driving.

I've found that the Eco mode works best when driving at a consistent speed on the highway. It helps to save even more fuel when there are fewer accelerations and decelerations.
