Apparently it's not expected by some readers that the gen2 diesel may provide no DEF warnings until there are just 300 miles to go. Another owner here indicated surprise, and I too expected way more than 300 miles warning.
Top off the DEF before you roadtrip!
Otherwise the car might decide that the first DEF warning (with 300-miles-to-go) and your enthusiastic first tentative clumsy DEF refill will be mandated to occur when you are in the middle of subzero windy blizzard conditions at a service area on I-90 near Erie & Buffalo.
