Using mountain mode to build up a charge

While driving on the highway, I used mm to build up some battery charge. At this point I wanted to place the car in the hold mode to retain the charge for later use in the city. However, the hold mode was not available. Later, I realized that I had no charge left on the battery. Should I have just left the car in mm until I got in the city?

If you used MM to build up some charge. You should stop somewhere and restart the car so they show up as EV miles.

However, I do not recommend using MM for charging the battery, unless you plan to drive in some very mountainous areas. Using the gas engine to charge the battery is not as efficient as using it in REX mode.
