I was driving today and noticed a red jack icon on my IC. The manual says this means jack mode is enabled but it wasn't (I didn't turn it on and even if I had I was going plenty fast for it to be auto disabled. It was definitely not the yellow version of the icon which the manual says indicates a problem with the system. I parked the car and checked that the system could adjust height correctly. Then I turned it off and back on again and the icon went away. Any ideas?
