Comfort and Convenience
Power folding mirrors matter at the moment of parking: a switch pulls both housings in against the doors, narrowing the car before you walk away in a tight space.
Safety and Driver Assistance
A driver senses a skid only after the car has begun to slide. ESP compares steering input with the car's actual rotation and brakes individual wheels to pull the line back.
Multimedia and Connectivity
Audio preparation supplies the wiring and speaker mounting points, so a head unit fitted into the dash aperture drives the cabin speakers and gives source and volume control from one place.
