Infiniti invented the Lane Departure Prevention System to help keep vehicles from straying out of its lane. It utilizes camera monitor the distance between the vehicle and the lane markings, and when the vehicle drifts unintentionally towards the lane markers, the system first sounds an audible warning. Then it will apply brakes to certain wheels to help move the vehicle back into its lane.
Disclaimer: The Lane Departure Warning/Lane Departure Prevention systems operate above the approximately 45 mph and only when lane markings are clearly visible on the road. They will not prevent loss of control. See your owner's manual for details.
