What does the 'Eco' button in the Kia Rio do?

I noticed there is an 'Eco' button in my Kia Rio but I'm not sure what it does. Can you explain its function?

The 'Eco' button in the Kia Rio adjusts the engine and transmission for improved fuel efficiency. It can also change the shift pattern for a more eco-friendly drive.

When you press the 'Eco' button, it activates the vehicle's idle stop system, which shuts off the engine when the car is stationary to save fuel. It also adjusts the air conditioning system for better energy conservation.

Using the 'Eco' button in the Kia Rio can help reduce your carbon footprint and save you money on gas. Plus, it's as easy as pressing a button!
