Comfort and Convenience
The on-board computer is read by cycling through its trip and consumption displays with the steering wheel or stalk button, each press stepping to the next screen; values are reset manually by holding that button.
Safety and Driver Assistance
Once the driver presses the brake hard enough to lock a wheel, ABS releases and reapplies pressure at that wheel many times a second, so the tyre keeps rotating and steering input still turns the car.
Multimedia and Connectivity
The 12V power outlet covers only the electrical supply side, feeding a charger or adapter from the car's battery; the audio signal itself still arrives through USB, AUX or the Bluetooth link.
