Comfort and Convenience
Power folding mirrors swing the housings inward at the touch of a switch, narrowing the parked car in tight bays; they address clearance, not the driver's view or seating position.
Safety and Driver Assistance
The passenger airbag protects rather than warns. It deploys from the dashboard only on a qualifying impact, so belts and the front seat position still do the restraining work beforehand.
Multimedia and Connectivity
The USB port handles the wired link to stored music, feeding digital files to the audio system and letting the head unit browse tracks, which an analogue AUX input cannot do.
