Comfort and Convenience
The multifunction steering wheel puts switches in the rim's spokes, so the hands that steer also change audio volume and scroll displays without reaching across to the fascia.
Safety and Driver Assistance
When a driver stabs the pedal but eases off too soon, brake assist reads that fast pedal movement and raises line pressure to full braking effort. It shortens nothing the tyres cannot hold.
Multimedia and Connectivity
The audio system is the amplifying and tuning stage: it picks the source, feeds the speakers and holds volume and tone settings, whatever device supplies the signal.
