Comfort and Convenience
The on-board computer acts on the instrument panel display, where a small screen beside the dials shows running data such as trip distance and consumption, replacing gauges that would otherwise crowd the cluster.
Safety and Driver Assistance
The electronic stability program assists rather than informs: it compares steering input with the car's actual rotation and brakes individual wheels to curb a skid, though it cannot exceed the grip available.
Multimedia and Connectivity
The audio system provides the head unit itself — the tuner, amplifier and control panel — so the driver selects a source and adjusts volume from fixed controls rather than through the connected device.
