safe mode? never heard of it... you can reset the pcm/ecu by pulling the ecm fuse out for 15 minutes or so, or by disconnecting the battery. keep in mind you may have to do an idle relearn after you do this.

some driver information centers are just quirky, and may never work right. are you sure you're resetting the functions properly? does it just say "miss op" when you are doing it? if so, you have to hold the reset button down until you see "miss op" disappear and the mileage resets.

if none of that works, you may just ned a new one.
