Not enough info given, Engine, Transmission, etc.
Best info on towing is in Your Owner's Manual. Max Towing, Tung Weight, Trailer Brake's, Brake Controller, Weight Distribution Hitch. Make sure that your Hitch Ball is also rated high enough.
Read and Study Your Owner's Manual is my advice. If Auto Transmission, have Nissan Double Check the ATF Level to make sure that it is not Low.
