Comfort and Convenience
Power folding mirrors retract inward on command, usually via the same switch that aims the glass. Each mirror is still positioned manually first: select left or right, then tilt until the car's flank just enters view.
Safety and Driver Assistance
Once the driver presses hard on the brake pedal, ABS monitors wheel rotation and releases and reapplies pressure many times a second at any wheel about to lock, so steering input still turns the car.
Multimedia and Connectivity
A USB socket confirms a physical connection and charging, but not that every handset will pass audio or data through it. Cable quality and the phone's own software determine whether playback or projection actually starts.
