I don't think that it will lower once in Jack Mode as it disables the air suspension sensors. Also, I think when the truck is in Tow mode that it disables the ability to change out of Normal mode and forces it to stay in normal, something else you may need to be aware of for when you arrive and try to get it lower to get out. I was worried about it changing modes on me based on speed while I was towing and it just always stayed in Normal, even over 106 km.Thank you.. I hope the truck will still lower once it is hooked up as I am in a wheelchair. It is tough enough to get into it when it is on exit/entry..
I might not have been clear about what I meant but I didn't mean with it hooked up, I meant when you put the truck in TOW mode. And maybe I am wrong about when its not moving, but it definitely will not change modes when the truck is moving in TOW mode. It was just a thought.I raise/lower mine all the time with the trailer hooked up. Entry/Exit makes it easier to get the hitch on/off the ball.
