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

I noticed there is an 'Eco' button on the dashboard of my Kia Picanto. Can you explain to me what it does and if it is worth using?

The 'Eco' button stands for 'Economical' and when activated, it adjusts the engine's performance and certain other systems to increase fuel efficiency. It is definitely worth using if you are looking to save on gas costs.

The 'Eco' button helps to optimize the overall driving experience by balancing power and efficiency. However, it may not make a huge difference in your daily driving.

The 'Eco' button can be useful in stop and go traffic or on long drives, but for short trips in city driving, it may not have much of an impact. It's worth trying out and seeing if it makes a difference for you.
