Your computer is telling you that it is time to service the 4wd system and/or there is something not right with the system. I would get it checked. best of luck.

Most likely it is one of the solenoids that engages the 4WD or some other electrical issue being sensed. Diagnosis with a mechanic's scanner will tell you where to start.
