My Ram 2500 showed same thing. My salesman told me that they low inflate one tire so the system will show up to make you aware that system is on the truck. He then showed all four tires and which one was underinflated so I could see how system works should the indicator light up when I was the owner. I was told that prior to delivery, all tire pressures, fluids and other components are rechecked to make sure they are at manufactures recommended specs.
DW and I took truck over night and both of us drove it for a half hour on all roadways we normally drive.
When I took delivery of the truck, the indicator was not on. I checked pressures and they were all at proper spec. Perhaps, and I was not there, that is what happened here. Oh, by the way, the ride did not change it. In fact, both DW and I agree that it rode exactly as stiff and truck like as the 2007 2500 we replaced it with. After all, it is a TRUCK.
Now, if your DH has taken all that air out of tires and no light is coming on, I would certainly take it to the dealership and have the unit checked as it must not be functioning properly.
Keep Truckin', keep it safe and Happy Camping!
