A system includes a differential, sensors, and a controller. The differential is operable in a first differential mode in which a first shaft and a second shaft are allowed to rotate at different speeds, and a second differential mode in which the differential inhibits relative rotation between the first and second shafts. The sensors are configured to measure vehicle operating conditions. The controller is in communication with the sensors and the differential. The controller, when the vehicle mode is selected, is configured to determine if an intended path of the vehicle is straight, determine if a vehicle speed is less than a predetermined vehicle speed, and operate the differential in the second differential mode for a predetermined time period in response to the controller determining that the intended path of the vehicle is straight and the vehicle speed is less than the predetermined vehicle speed.
