The C300 comes standard with 17-inch alloy wheels, automatic headlights and wipers, auto-dimming mirrors, dual-zone automatic climate control, a tilt-and-telescoping steering wheel, 10-way power front seats (with four-way lumbar), driver memory settings, MB-Tex synthetic leather upholstery and a 60/40-split-folding rear seat. Electronic features include the COMAND interface with a dial controller and a new smartphone-style touchpad interface that overlap many functions, a 7-inch display screen, Bluetooth phone and audio connectivity, an in-car WiFi hotspot and an audio system with a CD player, USB and auxiliary audio jacks and HD radio. Elegance and class are hallmarks of Mercedes-Benz interiors, but the 2015 C-Class delivers a new level of visual panache. Whether upholstered in standard MB-Tex synthetic leather or the optional genuine article, the cabin features exceptional materials quality and a cool contemporary design. Door panels fuse wood, soft-touch surfaces and metallic accents, and integrate tightly with the dash and instrument panel. It's a notable break from traditional Benz understatement and it's no surprise to learn that the cabin was conceived by Mercedes' design studio in Italy. Every 2015 Mercedes-Benz C-Class comes standard with antilock brakes, stability and traction control, front side airbags, front pelvic airbags (which deploy lower than the side airbags), a driver knee airbag, full-length side curtain airbags and a rearview camera. The C-Class now also comes standard with Collision Prevention Assist Plus and PreSafe, two features that can autonomously apply the sedan's brakes to avoid a collision and increase the effectiveness of the car's restraint systems in a collision. Attention Assist can also warn the driver of drowsiness or fatigue and, in conjunction with the navigation system, suggest possible places for a rest..
