Comfort and Convenience
The multifunction steering wheel duplicates existing controls under your thumbs, so you switch tracks or scroll the trip computer without releasing the rim; the buttons select and step, they do not physically move anything.
Safety and Driver Assistance
The electronic stability program assists rather than informs. It works through the existing brakes and engine management to help hold the intended line, and the driver still steers throughout.
Multimedia and Connectivity
Bluetooth handles the wireless link itself, pairing a phone to the car so call audio and stored music reach the speakers without a cable, while the head unit still sets volume.
