Comfort and Convenience
A multifunction steering wheel carries switches wired to systems mounted elsewhere, so audio or on-board computer readouts can be stepped through by thumb while both hands stay on the rim.
Safety and Driver Assistance
Electronic stability program does not steer for the driver; it senses that the vehicle is turning more or less than intended and brakes individual wheels to pull the path back toward the steering input.
Multimedia and Connectivity
A 12V power outlet supplies current only, feeding a charger or accessory. AUX and USB inputs instead pass a signal to the audio system, and USB can carry both roles at once.
