Comfort and Convenience
With the listed start-stop system, holding the car stationary on the brake shuts the engine down; releasing the brake restarts it automatically, so idling pauses at lights without the driver touching the start button.
Safety and Driver Assistance
On wet or loose surfaces a hard stop can lock a wheel, and the listed anti-lock braking system releases and reapplies pressure at that wheel. It shortens nothing by itself; it preserves steering during the stop.
Multimedia and Connectivity
The listed USB connection handles the wired side: it feeds a phone or memory device's audio files to the system and supplies power to the attached device, unlike the separate Bluetooth link.
