As per the title. If you put a trailer on it does it auto level so the car is level. Depending on what I read it suggests auto leveling is disabled in trailer mode...which would be dumb.
What do you mean with auto level? I didn't pull a heavy trailer yet but I think it corrected the height when I put my bikes on the bike rack so I think it is auto leveling to keep the car level.
Reading the Dutch manual: It will not do the speed level adjust and the location based level adjustment.
