Correct, the Maverick high voltage battery has no air filter like the Prius. All you need to do is make sure the coolant reservoir is at the correct level, just the same as the engine coolant reservoir. They are next to each other in the engine compartment.
I believe the reason for disconnecting the 12v battery is to prevent draining the high voltage battery as it is used to trickle charge the 12volt battery. The 12v battery is used to close the contactors connecting the inverter/converter to the drive motor and the starter/generator. The starting current 3phase AC (from the HV battery through the inverter) is sent to the starter/generator in the configuration to cause it to start the ice. With the 12v battery disconnected the HV battery would last much longer in storage.
The HV to 12V convert is disabled when the key is off.
I believe that the HV To 12v convert can be enabled subject to SOC of HV if needed. I further believe that turning the key on is notification to computer to get ready I want to go and turning it off is notification to shut things down (not necessarily instantaneously?? What if HV battery needs 10-15 degrees cooling when you turn key off). I guess we will find out when we get Mavs.
If so it would be different from all previous Ford Hybrids. One main reason is safety, the HV battery has deadly voltage. With the key off the HV is disconnected at the battery from all the high voltage wiring throughout the vehicle . Therefore there is minimal chance someone working on the vehicle could get shocked.
I think you completely missed the point of the post.
Did not consider that a problem. Just another item on list for neighbor or other house checker to do when necessary on their every 3rd or 4th day visit while away from home. Not something for other neighbors kid that feeds chickens daily to do. Could just install quick disconnect on 12v battery and put that on list with water heater vacation setting. Just remembered also need to get anti varmint motion activated noise makers for both my new XLT's when they "appear". (Had frontier PU parked 2-3 days couple years ago had rats build nest under hood ate insulation off wiring harness, battery cables, plastic off fuse panel, etc. Required 4 weeks at Nissan as harness was on BO as they had 3 others with same $5800.00 problem). Developer cleaning nearby 80 acres for new subdivision.
!Go Navy.
Nor is any vehicles with an internal combustion engine. Most of us have ethanol in our fuel, which reduces fuel shelf life. The lithium battery itself has a very low rate of discharge, but internal combustion engines don't like sitting for months unused.

I drive a Hyundai ioniq and they went a slightly different route with that car. They use a 12v lithium ion battery instead of a standard leaf acid. It is packaged along with the HV battery. The 12v battery can die if lights or something else drains the battery and if that happens you hit the "12v Battery Reset button" which temporarily uses the HV battery to charge the 12v battery which allows the car to start.
Early Ford Escape hybrids had this feature also even though they had a standard lead acid 12v battery. So you could still use jumper cables if you wanted. Seems they could not justify the extra cost since they dropped the 12V jump from HV battery feature around 2009.
As a CMax owner, how is the turning radius of Mav compare to your CMax. Our 2013 CMax energi had a horrible turning radius, one of the reasons we let that car go… I realize Mav is longer wheelbase, but any impressions?
