The airbag deployment is controlled by a very sophisticated algorithm. It looks for forces, and for certain kinds of forces, double checks to make sure two spots in the vehicle are seeing the same thing, within a certain period of time, then runs the math and makes a decision. The amazing thing you notice when you look at high speed crash films is that it does all that and starts to deploy the bag before the driver even starts moving forward.
Every time you start the jeep it does a self-diagnosis to confirm everything is working, then the light goes out.
I'd leave it alone except for the child seat issue. Though a huge oversimplification and generalization, a typical deployment takes at least the equivalent of running into something very solid at 14 miles per hour. It gets much more complicated on angled hits, but that is a ball park.
