Comfort and Convenience
An on-board computer reports trip and consumption data the vehicle can measure itself. It does not regulate cabin temperature, which remains the job of the separate air conditioner, nor does it promise any particular comfort level.
Safety and Driver Assistance
ESP acts on individual wheels to correct a skid once the vehicle starts deviating from the steered path, while ABS works only under braking, releasing pressure so a locked wheel can still be steered.
Multimedia and Connectivity
The audio system is the point where sources come together: whatever arrives via Bluetooth, USB or the AUX input is selected and played through it, so volume and source switching stay with the vehicle rather than the phone.
