Comfort and Convenience
Start-stop acts on the engine itself, shutting it down once the car is stationary and restarting it when the driver releases the brake, so the idle noise and vibration normally felt through the cabin fall away at a standstill.
Safety and Driver Assistance
Hill start assist responds to the driver lifting off the brake on an incline: it holds brake pressure briefly after the pedal is released, giving time to reach the accelerator without the car rolling backwards.
Multimedia and Connectivity
The AUX input carries an analogue audio signal straight into the audio system, so any device with a headphone output plays through the car speakers without needing digital recognition or a data connection.
