My new truck is supposed to have this and there is what appears to be a button to activate it. what the hell is it?

 

quote from a review of a 2003 silverado.

"The 4-Wheel Steering Package includes a manually selectable ride control system designed to enhance control when pulling a trailer. Press the Ride Control button when the truck is empty and the system seems to firm up the shock damping, which reduces the bouncing somewhat, but the ride becomes harsher. Ride control is probably best used for towing to reduce the tendency of the truck to pogo as the trailer goes over bumps, but it can also be used off road for better suspension control."

 

My '02 has the ride control and traction control. It's a 2wd. I noticed when I turn the ride-contol on, it gets bouncy and almost will not lose traction, even with the traction control off.
