Do all 2013 RT Ltd's have the ACS system installed? I purchased mine used and it does have the switch on the dash. When pushed it displays the bar on the left side of the display and says "MANUAL" vertically in the bar. I have to add air to the system every time I ride by the Schrader under the seat. It will go from 80lbs to less then 40lbs in the span of 24 hours. Something is wrong.:banghead:
