Comfort and Convenience
The on-board computer gathers signals from fuel, distance and speed sensors, then presents them as readouts the driver selects; the display itself changes nothing about how the car runs.
Safety and Driver Assistance
Once the driver brakes in response to a warning, the collision avoidance system can add braking pressure beyond the pedal input, shortening the stop without removing driver control.
Multimedia and Connectivity
The 12V outlet is a power connection only: it feeds a charger or accessory, while any music or navigation reaching the speakers travels along the separate audio wiring.
