Jeep Grand Cherokee Laredo Dashboard

My Vehicle Has A Light On The Dashboard That Says O/d Off. The Issue Is I Do Not Know Whether To Drive With This On Or Off. Can You Explain...

No Working Gauges On Dashboard, Etc, Mph, Fuel, Oil, The Signal Lights Work, Inside Lights Work, Head Lights Work, All Fuses Good , All...

My Dash Light For Gauges Quit, Then My Taillights And Tag Lights Quit Working. Also Bulbs Are Good But Can't Find Right Fuse Or Problem.
