Comfort and Convenience
The on-board computer gathers trip and consumption data, and the driver scrolls through those readouts using the steering wheel buttons, which step the instrument display from one value to the next.
Safety and Driver Assistance
Lane departure warning addresses unintended drift within a marked lane: the car tracks the painted lines and alerts the driver, who then corrects the steering themselves.
Multimedia and Connectivity
Bluetooth links the phone wirelessly for calls and streamed audio, with no cable involved. The USB connection instead carries a wired signal and supplies charging current at the same time.
