New member and trouble with tilt indicator

Hey guys,
So I just bought a 24 Tacoma sr5 4x4.
It’s new only 12 miles on it. At any rate
The tilt indicator gauges for Roll and Pitch are working, but the two middle numbers one up and one below are always on 30 and never change. I found an article that said if it reads 30 always it’s malfunctioning.
The dealership service advisor gave me the reason as it’s always 30 as it’s for the bed to show it for drainage. What? I don’t think so and they are running diagnostics on it now after we went a little higher in mgmt.
Any thoughts on the problem or not one?
Thanks

 

The 30 represents the highest you should safely go. That’s why it’s on the end of the gauge. It’s not a live updated number. The gauge goes blue when you go up in angle.

 

Thank you
