2003 Hummer H2:
My Driver Information alerts me to 'Service 4WD'. After checking the owner's manual, it merely states 'Check fluid levels' for axles & transfer cases. Done, but the warning light still comes on periodically. Is there something else that needs attention ?

Most service lights, like the light for an oil change, comes on by milage to let you know when to change oil, it has to be reset, Some reset buttons are in the Distbution power center, some are in the dash settings, some are just anywhere they want to put them. Does you owner's manual adress this? I realy could not tell you where to look for the reset button on a Hummer.
