Help!!!

So since there are some real knowledgable people on here regarding Internationals, I need help identifying a couple of toggle switched on my dash. One says ENAB/Off road. It is currently in the off road position. Then there is one that reads Lock/PDL. It is in the PDL position. I'm clueless to both and don't have an owners manual. Thanks!!

 

Its not too bad now that we got this International. I know a lot of people have said negative things about these trucks. But right now... Right this second? Yea, I'm happy to be moving. The truck for now runs pretty darn good. Had to figure out how to organize all our crap in the sleeper. We basically live in this thing so we have way WAY too much stuff. But we are moving. And so far freight is decent. Ran into that crazy mess in Dallas last week. And that set us back a little. But right now things are good. I want to give this a chance and not be a job hopper. But I also want to be treated FAIRLY. Not special. Just fair. We want to move back to Florida where our kids are. USX is fine with that but if we jump ship we may run into problems. Plus with this dedicated account we are guaranteed a certain number of miles. It's of course not cut and dry. Isn't pay period to pay period. There are plenty of rules. But it is something that we will be without if we go elsewhere. Another reason we don't want to bail. So all in all we are doing pretty good. Just want to keep driving.
