When I start my 98 TJ 4.0L, manual. All of the lights and gauges come alive then go back out, except the "check gauges" light hangs on after everything else goes out as well as the "airbag light" Finally about 5 seconds later the check gauges light goes out then about 10-15 seconds later the airbag light goes out. Now I can drive around all day, and they don't come back on until I start the Jeep again. There is nothing out of the ordinary with the gauges. Is this anything to be concerned about?
