I have a 1998 Cherokee Sport with the 4.0 engine. The airbag light keeps
coming on and off, sometimes for a long while, other times not long at all.
Luckily it hides behind the GPS so I don't always see it. I was thinking the
other day about the practicality of the jeep and wondering two things:

1 - What keeps the airbag from deploying while undergoing extremem four-wheel
drive conditions? 

2 - Can the airbag be safely disabled? If so, how?
