I tow my 2018 C-Max and have a question no one seems to be able to answer. The manual says that one needs to start the car each morning (when towing) and let the engine run for 1 minute. That sounds great, but after about 15 seconds, the ICE (internal combustion engine) shuts down changing to hybrid mode thereby not allowing me to run it for 1 minute. How doing I keep the ICE running?
