Comfort and Convenience
The listed multifunction steering wheel matters mid-journey: its integrated buttons duplicate audio, phone and trip-computer commands, so a running change is made with a thumb rather than a reach across the dashboard.
Safety and Driver Assistance
The listed passenger airbag responds after a crash sensor triggers: a gas generator inflates the cushion within milliseconds, spreading deceleration forces across the front occupant's head and chest instead of the dashboard edge.
Multimedia and Connectivity
The listed USB connection handles the wired side of an audio session, carrying track data and device control to the head unit while supplying charging current, so a phone or stick plays without draining itself.
