What does the 'S' mode in the Kia Rio's transmission do?

I noticed a 'S' mode on the Kia Rio's transmission. What does it do and when should I use it?

The 'S' mode stands for 'Sport' and it will change the gear shift points, making the car more responsive and allowing for more spirited driving.

You should use the 'S' mode if you want a more engaging driving experience, such as when driving on winding roads or when you want quicker acceleration.

Be careful when using the 'S' mode as it will also affect your fuel economy. It's best used for short bursts of acceleration rather than prolonged periods of driving.
