We used to own a 2003 2500 HD Silverado Duramax/Allison combo. After a few thousand miles, I remember re-setting the DIC mileage display, so that we were getting a re-calibrated and accurate calculation of the fuel that was used.
We now own a 2009 Tahoe. 5.3 litre and I would like to know if anyone is aware of a simiilar procedure for this vehicle?
As I recall, one of the DIC buttons had to be held down and the accelarator pedal was depressed....
Any ideas, or is this something new?

Thanks for the advice and I managed to push the correct DIC buttons. It will be interesting to see what mileage numbers we are achieving. Tahoes are advertised as getting 30 mpg, BUT I am highly skeptical. Perhaps in a perfect world, but at 130 - 140 KPH on the highway.......
30mph really? I don't think I have heard that unless they are referring to the Hybrid in town on a flat surface, with no traffic lights and the wind at your back and the moon directly in front causing a tidal pull on the truck...
I have seen 23mpg for a portion of a tank on level highway at 50mph with the 5.3...
yeah I don't think you will see 30mpg. but if you do some highway at 60mph I am sure you could get some good numbers.

in our '07 2wd with the 3.42 gears I get right at 19.5 - 21.00 mpg with all highway (14 - 16 city). best mph is around 60 - 65 for mileage but feels so dang slow when people are flying by you. I usually just set cruse at 70mph.
