Comfort and Convenience
Power folding mirrors retract the mirror housings toward the doors to narrow the car for tight parking or washing. They protect the glass from passing knocks, but they do not widen the rearward view once unfolded.
Safety and Driver Assistance
The passenger airbag responds to a crash signal rather than a driver command: sensors detect the deceleration, and the inflator fills the cushion within milliseconds so the front occupant meets fabric instead of the dashboard.
Multimedia and Connectivity
The audio system handles sound reproduction through the car's speakers and controls, while Bluetooth is only the wireless link that carries a phone's audio or calls to it. One plays, the other connects.
