For Lane Change on Demand,* when the driver activates the turn signal, the system will look for an acceptable opening in the indicated lane and alert other vehicles that a lane change is imminent. If the indicated lane is determined to be open, the vehicle will merge into the desired lane. Or, if the desired lane is unavailable, the system will notify the driver that merging must be manually completed. The system will display messages, such as “looking for an opening” or “changing lanes,” to keep the driver informed.
