Standard safety features include four-wheel-disc antilock brakes, traction control, electronic stability control and curtain airbags. The interior is well appointed with a navigation system, satellite radio, dual-zone automatic climate control, leather seating and memory drivers seat. Available features include adaptive bi-xenon headlights, blind spot detection and adaptive speed control.The 300C receives minimal changes for 2012.
