Comfort and Convenience
The listed on-board computer matters mid-journey: it draws range, consumption and trip data from sensors already fitted, so a driver can judge whether a fuel stop is needed before leaving a motorway.
Safety and Driver Assistance
The listed electronic stability program addresses a cornering slide on a wet or loose surface. It brakes individual wheels to pull the car back onto line, but it cannot exceed the grip the tyres still have.
Multimedia and Connectivity
The listed audio system handles playback: it decodes the source signal, applies volume and tone settings, then amplifies the result to the cabin speakers, with the head unit acting as the central control point.
