If you have the electronic locking diff, that's how you activate it. If you don't, I don't think that **** should pull out at all.
Can someone confirm this?

Not a dumb question at all. Pulling the switch out will engage your locking rear differential. It can give you more traction but makes it easier for the rear end to come around. It will automatically disengage when you go over 20 MPH.

Really the only time you should pull it is if you're concerned about getting stuck. It's useful for situations where one wheel is on something slippery and you need more torque to the other wheel to keep going. Off-roaders love their locking differentials, but the majority of times you just don't need it.

It disengages above 20 MPH for safety; otherwise the rear end would go sideways the instant you broke traction. With an open differential it's more likely that one wheel would break free leaving the other planted to keep the truck going straight.
