You should be fine to drive it home, as long as you don't drive it like that all year. There are a few things that activate the 4WD and one of the components has a failure and needs to be addressed. Good luck and hope this helps.

first, code b0100 is a fault in the restraint system. front end sensor, restraint sensing diagnostic module or communication between the 2 are suspect problems po420 is an efficiency problem with catalytic converter. most likely would need new converter, but exhaust leaks and oxygen sensor malfuctions can also set code. if this vehicle is under 80,000 miles and does need converter, dealer should repair for free under warranty. that is federally mandated.

The fog lights run by default during the day in the "auto" position. To activate the headlights and the fog lights you need modify the jumper position in the fuse box for the lights. "see fuse box diagram"
