What does the ECO button do in a Kia Ceed?

I recently bought a Kia Ceed and noticed there is an ECO button on the dashboard. What does this button do and should I use it while driving?

The ECO button stands for Eco Mode and it helps to improve fuel efficiency by adjusting the engine and transmission settings. It is recommended to use this mode while driving for better fuel economy.

Using the ECO button can also make the accelerator pedal less responsive, which can be useful for beginners or in heavy traffic. However, it is not recommended for driving in hilly or mountainous terrain as it can decrease power and performance.

The ECO button can also decrease the air conditioning output to save energy, so it may not be the best option on hot summer days. It is best to experiment with the ECO button and see if it works for your driving style and environment.
