Comfort and Convenience
The on-board computer has nothing to switch on or turn up: it reads data the car already gathers and cycles through readouts such as consumption or range as you press the stalk button.
Safety and Driver Assistance
ABS governs braking under heavy pedal pressure. Sensors watch each wheel's rotation, and if one is about to lock the system releases and reapplies that brake rapidly, so steering input still turns the car.
Multimedia and Connectivity
The navigation system handles the route side rather than sound reproduction: it fixes the car's position, plans a path to an entered destination, and interrupts the audio output with spoken turn prompts.
