Well just that you are aware the safety system is off... yes its ok to drive really cautiously. I have same issue and don't worry too much. Easy to reset with an OBD dongle. You get them from Target, K-Mart, Supercheap, Autobarn, or internet. Cost $1.99 for piss-poor (but cheap) Chinese Android crap, best bluetooth module is about $150 with software.
