What does the Kia Rio's Idle Stop and Go system do?

I've noticed that my Kia Rio has an Idle Stop and Go system, but I'm not sure what it does. Can you explain?

The Idle Stop and Go system helps to reduce emissions and improve fuel economy. It automatically turns off the engine when the car is stationary, and restarts it when the brake pedal is released. This can save you money on fuel and reduce your carbon footprint.

The Kia Rio's Idle Stop and Go system can be convenient when stuck in traffic or at long red lights. It also helps to reduce engine wear and tear, as the engine is not constantly running at idle. However, if you find it annoying, you can turn it off by pressing the 'ISG' button on the dashboard.

I've found that the Idle Stop and Go system can be helpful in city driving, but it may not be as effective on longer trips. To get the most out of it, try to use cruise control on the highway, as long periods of idling can decrease its effectiveness.
