Comfort and Convenience
The on-board computer reports values such as trip distance and consumption averages calculated from sensor data. It describes what the car has done; it does not adjust cabin conditions, which stays the job of the single-zone climate control.
Safety and Driver Assistance
On a wet or loose surface, ESP detects that the car is turning more or less than the steering implies and brakes individual wheels to correct it. It works only within available grip.
Multimedia and Connectivity
The USB port is a wired connection that can carry audio files from a stick or phone while also supplying power. Bluetooth instead links a device wirelessly, typically for streaming and hands-free calls.
