The suite of new safety features extended from an eye-tracking Driver Monitoring System to a lane departure warning system.[22][23] The pre-collision system added the first production image processing chip in a car capable of identifying vehicles and pedestrians in real time,[24][25] along with millimeter-wavelength radar, stereo cameras, and infrared night vision projectors.[24] A rear pre-collision system with whiplash-preventing active seat headrests and dual-chamber front airbags was also introduced.[22][26]
