When playing music via Bluetooth, the artist/song will not be displayed. Only if your stereo has an iPhone connection and your iPhone is connected into it.

Fuel tank: 55 litres; the warning light typically illuminates with 50 kilometres remaining. However, this is what the computer says.
I was never able to add more than 43 litres. Thus, when the light comes on, you could drive an additional 120-130 miles.
