SpaceX uses the Merlin Vacuum engine on the second stage of the Falcon 9 launch vehicle. Does the merlin vacuum engine gimbal or does the second stage uses only nitrogen cold gas thrusters for attitude control?

According to the Falcon Payload User's Guide posted on the SpaceX website, the 2nd stage engine gimbals. (Emphasis mine)
