If that doesn’t work here is the alternate method.From the screen “Settings - Vehicle -Emergency tow”
It does require 12V but I don’t think you have to turn it on. This is the method used when there’s a software problem and there’s no menu. There’s also a full video on towing with all the details.Thank you! And I’m assuming this method is meant if no power available to truck at all so don’t have the accessory power on, correct?
