Turn the VDC off. It will then give YOU full control of the throttle. There are times that it's beneficial to be able to use throttle control in slippery stuff. The VDC will detect wheel spin, and chop the throttle, leaving you potentially stuck!
The VDC switch has no affect on the ABLS. The ABLS makes the new platform much better in the sand unless someone has added lockers front/rear.
I've been off-roading in sandy FL for decades. I've owned vehicles that would get stuck just looking at sand. The new platform works so well, you'd have to REALLY try to get it stuck.
