12V battery - check level?

Hi,
Does anyone know how to see the charge state of the small 12V battery stashed somewhere in the c-max?


I assume this battery is principally used for starting the gas engine but don't know much else about it. I am planning to flat-tow my c-max behind a motor home and the brake system guys recommend using a battery charger from the coach.


I have a portable system, RVibrake3, but don't plan to plug it into the car's battery. Rather I'll use a separate power pack. What I don't know is what other power drains there will be when towing car while turned off. I'd like to be able to check the status of both the high-voltage battery - which you can see on the dash, but also the small 12V battery. I assume this battery is charged by the engine and not linked in any way to the high-voltage system.


If anyone has some insight into this, please let me know.


Phil
