owners manual stats Jeep may have passive steering lock if equipped, had my jeep at the dealer today and confirmed my belief, steering wheel does not lock so there is no reason to leave key in acc and disconnect battery cable. Will tow the 2014 just as I did the 2013. To check start jeep turn wheel 1/2 turn, cut of jeep remove key, then turn wheel if it does not lock then it is not equipped with passive steering lock according to Jeep dealer. I believe it is in the manual just to protect jeep from anyone dragging a jeep with a locking steering wheel and then trying to sue for damage.
