I purchased a 2002 T/C I had two questions, found the answer to one of them with the search. Here is the other one: The overhead console shows what appears to be adjustable rear suspension with on/off and 3 settings. Is this correct? When should it be on and when off? No owners manual so I need your help.

 

You can download the manual from Chrysler.

 

there is no adjustable rear suspension on a minivan. They have load leveling shocks available but that's it.

 

After experimenting with the buttons I discovered they open/close the sliding doors and back hatch.
