Comfort and Convenience
The multifunction steering wheel moves the controls onto the spokes: thumb buttons under each hand switch audio tracks and step through computer readouts, so the hands stay on the rim.
Safety and Driver Assistance
The passenger airbag only inflates once an impact is already happening, cushioning the occupant against the dashboard. Nothing about it slows the car earlier, so a following gap still prevents the collision.
Multimedia and Connectivity
The audio system handles source selection and playback: it decodes the track arriving from the USB connection or radio tuner, then feeds the amplified signal to the cabin speakers.
