The side blind zone alert system is a feature that utilizes two side object sensor modules to provide enhanced customer convenience by sensing and reporting to the driver that an object is present in one of the driver's side blind zones. This is communicated to the driver by illuminating an icon on the left or right side view mirror, depending on what side of the vehicle the object is detected. This lane change assist system is radar based system in which the sensors transmit and receives energy that is reflected from external objects and used to determine if that object is an object of interest. Although this system is intended to help drivers avoid lane change crashes, it does not replace driver vision and therefore should be considered a lane change aid.
