Comfort and Convenience
The multifunction steering wheel duplicates existing controls rather than adding new ones: its buttons select a track or answer a call, while the volume or dual-zone temperature level itself is still set by degree elsewhere.
Safety and Driver Assistance
Automatic slip regulation acts when a driven wheel spins on loose or wet ground, cutting torque or braking that wheel. It restores traction already available; it cannot create grip where the surface offers none.
Multimedia and Connectivity
The USB connection serves the audio system as a data link, letting the head unit read files from a stick or phone and display track information on screen, unlike the 12V outlet, which only supplies power.
