Comfort and Convenience
The on-board computer acts on the instrument panel, using a small display between or beside the dials to show trip and consumption readings that would otherwise require separate gauges in the cabin.
Safety and Driver Assistance
The driver's airbag responds to a crash signal rather than a control input: it inflates from the steering wheel hub and deflates through vents, so the torso meets a cushion instead of the wheel rim.
Multimedia and Connectivity
The AUX audio input handles only the sound itself, taking an analogue signal from a headphone socket into the audio system. Track selection and volume stay on the connected device unless the head unit adjusts output.
