Comfort and Convenience
The listed on-board computer gathers data from vehicle sensors and presents readings such as trip distance and consumption; the multifunction steering wheel usually carries the buttons that cycle those displays without releasing the rim.
Safety and Driver Assistance
The driver's airbag protects rather than informs or intervenes: it inflates only in a qualifying frontal impact, spreading deceleration loads across the head and chest while the belt holds the occupant in position.
Multimedia and Connectivity
The 12V outlet handles no audio or data signal at all; it supplies direct-current electrical power from the vehicle system, so adapters and chargers plugged into it work independently of the USB and Bluetooth links.
