Comfort and Convenience
Power mirrors move the glass by motor from a switch inside the cabin, so they set the field of view. They do not widen it, and blind spots beside and behind the car remain.
Safety and Driver Assistance
The driver's airbag acts only once a collision is under way, cushioning impact against the steering wheel. ESP works earlier, damping a skid through selective braking so the crash may not happen.
Multimedia and Connectivity
A USB connection lets the system read files from a memory device, so tracks and folders can be browsed and chosen through the car's own controls rather than on the device itself.
