The mode changes, as below, whenever the DRIVE MODE button is pressed.

In NORMAL mode, the engine and transmission control logic work together to provide smooth everyday driving performance with an emphasis on comfort and fuel efficiency.
SPORT mode

SPORT mode manages driving dynamics by automatically adjusting steering effort and the engine and transmission control logic for more responsive Hyundai Accent performance.

In SPORT mode, fuel efficiency may decrease.
