Comfort and Convenience
The start-stop system can shut the engine at a halt and restart it when the driver prepares to move, so a wait at lights or in a queue need not keep the engine running the whole time.
Safety and Driver Assistance
Anti-lock braking (ABS) works on wheel lock during a hard stop so steering input can still take effect, whereas ESP acts when yaw differs from the steered path by braking individual wheels and cutting drive.
Multimedia and Connectivity
Plug a portable player's headphone lead into the AUX audio input and the audio system can carry that analogue source through the cabin speakers on an ordinary drive.
