Comfort and Convenience
The on-board computer gathers readings from sensors around the car and presents them on the instrument display, so the driver reads consumption or range figures directly rather than inferring them from the fuel gauge alone.
Safety and Driver Assistance
Under hard braking on loose or wet surfaces a wheel can lock and stop steering. ABS detects that through wheel-speed sensors and releases pressure briefly at the affected wheel; it cannot shorten every stop.
Multimedia and Connectivity
The USB connection carries digital data, letting the audio system read files and show track names, while the AUX input accepts only an analogue signal already decoded by the connected device.
