Comfort and Convenience
The on-board computer acts on the instrument cluster display, where it gathers trip and consumption readings and shows them in sequence as the driver steps through with a stalk or wheel button.
Safety and Driver Assistance
Automatic slip regulation assists rather than informs: when a driven wheel turns faster than the car is moving, it trims engine torque and brakes that wheel to restore grip during acceleration.
Multimedia and Connectivity
The USB socket is only a wired path between phone and head unit; the tracks, podcast or projected interface travelling along it come from the phone, while the dashboard controls playback.
