Maybe I'm just an inconsiderate ass, but I feel a mix of disbelief and anger that a car company thinks that governing a car to 4mph is acceptable for any reason, much less emissions fluid.
"There is a five gallon urea tank – with a filler neck in the trunk, underneath an access panel. You must be very careful to never let the fluid tank run dry. Because if you do, the car will punish you. The computer will first slow the car to a 65 MPH max – dropping to 55 if ignored. Continue to ignore the dashboard lights and eventually, the car’s computer will cut the max speed to 4 MPH. Yes, you read that right. Parking lot creep. No more."http://ericpetersautos.com/2013/07/02/2 ... ze-diesel/
