Methods for operating a vehicle as the vehicle approaches an intersection with a traffic control device are provided herein. One example method includes detecting a traffic control device at an intersection the vehicle is approaching, and releasing and applying a disconnect clutch arranged in a driveline of the vehicle intermediate an engine and a starter/generator based on a type of the detected traffic control device. Because releasing the disconnect clutch disconnects the engine from the vehicle driveline, the engine may be turned off to increase fuel efficiency while the disconnect clutch is released.
