rytis Posted February 10 Report Share Posted February 10 Hi does anyone know what this motor mode is, the nut is running continuously, it doesn't come on in electric mode why is this happening? Quote Link to comment Share on other sites More sharing options...
grege Posted February 10 Report Share Posted February 10 I believe the cmax does that when the engine is working to purge any excess moisture; excess moisture is bad for engines because it generates acid if not cycled hot enough. Too many people simply shut off hybrids when the engine starts running; ideal is to let it run until the engine stops on its own before turning the car fully "off". Someone else will likely chime in soon with any other deets. Greg Quote Link to comment Share on other sites More sharing options...
homestead Posted February 10 Report Share Posted February 10 Must be an energi message, never saw that one on my hybrid. I bought our car in april of 2013 and it got great mileage all summer then when winter hit I noticed it would run forever before it would go into electric mode. Then I discovered turning the heater off or turn it down and use the seat heaters when the car was cold. After a couple of miles the car would be warmed up and could get some heat out with the ice running continuously. Even doing that I still took a hit on mpg's in the winter.

cr08 Posted February 10 Report Share Posted February 10 (edited) This is what Ford used to call the 'oil maintenance mode' on earlier model years and changed it up to this confusing wording later. This mode only exists on Energi models and will run if you have too many drive cycles where the ICE starts but runs in short bursts or otherwise doesn't come up to full temp. Many will see this during the colder months of the year with cabin heat being used especially if you stay on EV Auto mode. It's normal and it is designed to run the ICE full time until it gets hot enough for long enough to boil off accumulated moisture in the oil. It'll continue to run even between vehicle restarts until it is satisfied. A quick way to end it is to get on the highway and drive it for a bit so it is under a consistent engine load and maintains the coolant/oil temp it needs. Just keep in mind that once it finishes, it'll drop back to 'Auto' operation and with plug-in charge available that means it'll be running on EV power primarily and you'll want to switch back to EV Later while still on the highway to help protect the battery.
