Comfort and Convenience
A press of the stalk or steering wheel button steps the on-board computer through its stored readouts, so the display switches immediately between trip distance, consumption and range without the driver leaving the current view.
Safety and Driver Assistance
ABS prevents wheel lock so steering remains possible under heavy braking, but it cannot shorten the distance physics demands. The gap ahead still determines whether the car stops in time.
Multimedia and Connectivity
A USB socket carries both charging current and data, yet what plays depends on the file formats and device protocols the head unit recognises; the cable alone does not guarantee a readable library.
