Comfort and Convenience
Power mirrors adjust the glass electrically from a switch, so the driver can set the view while seated. They only aim the mirrors; they do not widen the field itself or remove the blind spot behind the car.
Safety and Driver Assistance
Emergency brake assist reads a hurried pedal push and applies full braking pressure sooner than the driver's foot alone would. The anti-lock system works afterwards, releasing and reapplying pressure so the wheels keep turning and steering.
Multimedia and Connectivity
The USB connection carries digital audio from a phone or memory stick to the audio system, so tracks and folders can be browsed through the car's own controls rather than handled on the device.
