What does the cluster control on a 2006 Dodge Ram 1500 Larimie?

Trying to download the manual but something is either wrong with the website, very slow, says going to take 55 minutes to download and I have VERY high speed isp. I will let you know what I find

Thanks. I'm having trouble with the mileage reading correctly, the overhead with wrong avg. miles per gallon. Dodge changed the cluster and of course it still wasn't working correctly. So I took it back and now they've had it since last Thursday morning and still nothing. He called a couple hours ago and said, it would be 3 hours labor to dig deeper into it. I'm 1000.00 into the cluster replacement.

Wow...and a Dealer? That will set you back yet another $300 at Dealer rates with no assurance of a fix. It's still downloading

Well...(bad word) after all that the manual is no help..sorry 'bout that, all it shows is how to use all the controls for cluster.

I'm just trying to find out the purpose of the cluster, what it controls in the truck?
