Oh, ok. NS: I was under the impression that you were hooked up to your rig, put 'er in reverse, and the lights didn't come on. But it sounds like you're going by what the dealer said (which we all know can be total crap, Gospel, or anything in between.) I bet if you hook up and check this feature, it works.
In fairness, a lot of dealer salespeople don't know jack spit. For instance, I originally ordered my 30HFS-5 with a gray exterior, and I paid an extra premium for that. But when it arrived at the dealer, it was white. I was told by my sales guy, "They stopped making it in gray for the 2015 model year." (I had ordered it in March of 2014, so we were going off 2014 specs and thought I'd be getting a '14, but it took them so long to make it that it came through as a 2015.) Ok, I say, I'm SOL. Then 2 months later I go to Hershey and see most of the 2015 XLR line on display there in gray. Needless to say I was less than thrilled. I don't like being lied to. If you f$*#ed up, admit you f$*#ed up. I think there's just some defective gene in salespeople that requires them to lie periodically. Or at least talk out their butthole.
