Comfort and Convenience
The start-stop system exists to cut idling fuel use, not to alter cabin comfort; it shuts the engine at a halt and restarts it when the driver releases the brake.
Safety and Driver Assistance
Automatic slip regulation assists rather than protects or informs: when a driven wheel spins up, it trims engine torque or brakes that wheel to restore grip during acceleration.
Multimedia and Connectivity
The AUX audio input carries only an analogue sound signal from a headphone-style plug. Bluetooth, by contrast, links wirelessly and can also carry call audio and track data.
