2014 3500HD button on dash. What does it do?

[Hay Dude]

Still truck shopping for an HD.
Have seen a few with this button/knob. What is it for?
Some 2500/3500 HDs don’t have it.

My 2011 Chevy 2500 does not have a button like that.

Looks like it is probably an optional pto control.

Exahust brake?

Whatever it is , it's in an awkward place for the driver to access.

I believe Rj nailed it, PTO control.
Here's a link to an owners manual if ur interested: https://cdn.dealereprocess.org/cdn/servicemanuals/chevrolet/2014-silverado2500hd.pdf

Looks like that is what it is, mystery solved.

Thanks, I looked for about 10 minutes and couldn’t find what it was.
Makes sense as it was on a 3500 cab/chassis with a dumping flatbed.
Pickups mostly have a cubby hole.

I know what a PTO is but since I didn't know what it imply exactly here it is...

How It Works​

2020 GM HD trucks will utilize a PTO that’s drive gear operated via a chain to direct engine power. Since PTO on the trucks is engine-driven rather than turbine-driven, owners can use the PTO while the vehicle is idling. A button inside the cab enables the PTO, and a mode selector allows adjustment of load and torque output.

The General says that the 2020 GM HD trucks will be the first in the HD truck segment to feature a fully integrated PTO system.

Most are on the side of the Allison transmission.
