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

I've noticed there's an 'Eco' button in my Kia Ceed. What exactly does it do and when should I use it?

The 'Eco' button adjusts the engine and transmission to improve fuel economy. It's best to use it during highway driving or when stuck in traffic.

If you're driving in urban areas, it's recommended to keep the 'Eco' button on for better fuel efficiency. However, for quick acceleration or overtaking, it's best to turn it off.

I find that keeping the 'Eco' button on at all times helps improve my overall gas mileage. Give it a try and see if it works for you!
