Comfort and Convenience
Power mirrors let the driver adjust the exterior glass electrically from the seat, setting the rearward field of view. Clearing condensation or frost from that glass remains a separate function, handled by heating or the climate control.
Safety and Driver Assistance
A passenger airbag acts after a collision has already begun, inflating in milliseconds to spread deceleration forces across the front occupant. Attentive observation can avoid a crash; the airbag only limits injury once impact is unavoidable.
Multimedia and Connectivity
The USB connection carries digital data rather than an analogue waveform, so the audio system reads compressed music files from a stick or phone and decodes them itself, unlike the AUX input's ready-made analogue signal.
