Abstract
A method of controlling a vehicle includes determining if a diesel emission fluid is at least partially frozen, and determining if the vehicle is currently operating in a low diesel emission fluid inducement protocol. If the vehicle is not currently operating in the low diesel emission fluid inducement protocol, and the diesel emission fluid is at least partially frozen, then a temporary minimum diesel emission fluid mass may be defined to prevent entry of the vehicle into the low diesel emission fluid inducement protocol.
