Comfort and Convenience
The on-board computer matters mid-journey: it gathers running data such as consumption and range and shows it in the instrument display, letting the driver judge whether a fuel stop is needed.
Safety and Driver Assistance
Emergency brake assist reads how quickly the pedal is pressed. A driver who brakes fast but not hard enough still gets full boosted pressure, which no amount of watching the road supplies.
Multimedia and Connectivity
Bluetooth confirms a wireless pairing route for calls and streaming, but not which profiles a given handset supports, so contact lists or track titles may not appear on the head unit.
