Lane Change Assist (LCA) monitors the areas to the rear of the vehicle and the blind spots on either side. It issues a visual warning signal in response to vehicles detected in the next lane.
Lane Assist uses a camera installed in the front end to detect divider line markings on the road. If the car threatens to cross one of the lines, the system steers the vehicle back into the center of the lane automatically. This correction is accompanied by a soft steering pulse. Of course, you are able to override the system at any time.
