Comfort and Convenience
The on-board computer is read and stepped through by hand: a stalk or wheel button cycles the display, so fuel and trip readings appear one screen at a time as the driver selects them.
Safety and Driver Assistance
A sharp frontal deceleration fires the driver's airbag, filling the space between chest and steering wheel before the belt alone has stretched far enough to let the torso reach the rim.
Multimedia and Connectivity
A USB socket confirms a wired connection point, not what the head unit will read from it: supported file formats and whether a phone charges or plays through it depend on the system's software.
