Comfort and Convenience
The listed start-stop system acts on the engine itself, cutting it at a standstill and restarting it as the driver lifts off the brake, so the idling noise stops.
Safety and Driver Assistance
Hill start assist briefly assists rather than protects or informs: it holds brake pressure at the wheels for a moment after the pedal is released, giving the driver time to pull away.
Multimedia and Connectivity
The AUX audio input handles only the signal path in: a cable carries analogue sound from an external player into the audio system, which then sets volume and feeds the speakers.
