What does the Eco Mode do on a Kia Picanto?

I just bought a Kia Picanto and noticed that there is an Eco Mode button on the dashboard. What exactly does this mode do and should I be using it regularly?

The Eco Mode on a Kia Picanto decreases the engine's performance in order to improve fuel efficiency. It adjusts the engine's power and torque output and can also affect the air conditioning and other electronic systems. It's recommended to use the Eco Mode for regular city driving and switch it off for extra power on the highways.

Eco Mode can also help reduce your carbon footprint by lowering CO2 emissions. If you care about the environment, it's a good idea to use this mode when you can.

Personally, I only use Eco Mode when I need to save some gas or when driving in heavy traffic. It can be annoying when trying to merge onto the highway or when going up a steep hill.
