Comfort and Convenience
The on-board computer reports trip data such as consumption and range; it reads values rather than sets them. Changing consumption still means altering speed or the listed single-zone climate control settings.
Safety and Driver Assistance
The listed stability program acts when wheel speeds indicate the car is turning more or less than the steering suggests. It brakes individual wheels to restore the intended line, working automatically without driver input.
Multimedia and Connectivity
The audio system handles the output stage: it decodes the chosen source, whether radio or a connected phone, and drives the speakers, while Bluetooth or USB only carry the signal to it.
