Comfort and Convenience
Scrolling the on-board computer's stalk or wheel button steps through trip data on the instrument display, so fuel use and range appear without touching the separate climate controls.
Safety and Driver Assistance
ABS reads wheel speed sensors and releases brake pressure many times a second when a wheel locks. A driver senses a skid only after it starts, and cannot modulate that fast.
Multimedia and Connectivity
A Hi-Fi audio system describes amplification and speaker quality, not connections. Whether a given phone or memory stick plays depends on the USB, AUX and Bluetooth sides, each with its own format limits.
