OK, I just towed the C-Max yesterday and turning on the heat or A/C does keep the ICE running. I have yet to try pushing the pedal all the way to the floor, but will try that soon.  Thanks to all who gave me their thoughts.

I will experiment on these 2 ideas.  It is just surprising the manual does not make mention of this issue.  Thanks again for the suggestions.

I must be missing something here. I know you may need to depress the pedal to the floor to start the ICE, but if I depressed it for 1 minute the RPM would increase too high.  Let me rephrase my question.  I depress the pedal to start the ICE running.  Then I take my foot off the pedal.  What sometimes happens is the ICE stops running before the 1 minute is up (sometimes only 15 seconds) and is operating on the battery.  I believe I am supposed to let the ICE run for 1 minute. I hope this clarifies my question.  Thanks for trying to help. 

I have not spent a lot of time on this  forum, but yes, I did pick up the C-Max (Titanium) in Montana last May. I must say that I love the car.  The visibility is one big advantage.  I must also add that my other car is a 2017 PriusV.  I am to old to be hot rodder, so how quick a car is off the line is not important to me.  Both cars have ample power in my book.  I prefer driving the C-Max, but that might be because of all the technology the C-Max has.  I should have ordered the Prius the same way.  Never too old to learn.

Yes, I understand that, but what happens is the ICE shuts down after about 15 seconds.  The question is, how do I keep it running.

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?

I have a 2017 Prius V and ordered a 2018 C-Max.  Although I will be the primary driver of the C-Max and my wife the Prius, it will be interesting to see how the mileage compares.

Why all the Prius Bashing.  A little defensive?  I bought my first Prius in 2017, put 115K miles on it and the only service I had done were oil changes.  My history with Ford has been problematic.  I bought a 2012 Focus because I can flat tow it behind my motorhome which is on an E450 chassis.  The focus has had major transmission clutch work done 3 times and my motorhome had it's engine removed to replace valve guides due to service bulletin about excessive oil consumption.  Then, the transmission blew.  I never did like the Focus, but there are not many options that are automatics you can flat tow behind a motorhome.  I recently found out that you can flat tow a C-Max, so I bought one that was in route to Montana from Michigan.  That was the first week of March and I am still waiting it's arrival.  Now I am being told it will arrive toward the end of the month.  We will see.
