Every 2014 Mercedes-Benz C-Class comes standard with antilock brakes, stability and traction control, front side airbags, front pelvic airbags, a driver's knee airbag and full-length side curtain airbags. Also standard are mbrace2 emergency communications and Attention Assist, which automatically monitors the driver for signs of fatigue or inattention and wakes them back up, so to speak, with audible and visual warnings. Rear side airbags are optional. The Lane Tracking package adds a blind-spot warning system and a lane-departure warning system. The Driver Assistance package adds the lane-departure warning, adaptive cruise control and PreSafe brake (active braking system that can automatically apply the brakes if a collision is deemed imminent and the driver doesn't heed the visual/audible warnings).
