Comfort and Convenience
An on-board computer reports values such as consumption and range from sensor data and recent driving, so it describes conditions the car has measured rather than promising how the cabin or the journey will feel.
Safety and Driver Assistance
A passenger airbag does not respond to steering or braking inputs; crash sensors fire it only during a qualifying impact, inflating and venting within a fraction of a second to cushion the front occupant.
Multimedia and Connectivity
A 12V power outlet carries only electrical power, not audio or data. It can keep a phone charged, while the music itself reaches the audio system over a separate AUX, USB or Bluetooth link.
