You can thank the EPA for that one, actually it's worse, it starts a counter, after so many starts (n = 16), you get NO start...
From my 2014 ML350 manual explaining the add DEF messages on the console:
(When you get the message “xx Starts Remaining”)
The DEF level has fallen to a minimum. You can start the engine a further 16 times.
Have the DEF tank filled immediately at a qualified specialist workshop.
You can start the engine a further 16 times. If DEF is not added, it will then not be possible to restart the engine. Refill the DEF tank with approximately 1 gal (3.8 l) DEF.
I remember reading a story about an ambulance hitting this hard limit and it resulted in a bad deal for the patient involved.
