Dispense DEF into Vehicle

What happens here

Grasp the dispensing nozzle, which is attached to the clear plastic hose from the elevated DEF barrel. Insert the nozzle fully into the vehicle's DEF fill port. Since the system is gravity-fed, the fluid will begin to flow into the tank automatically once the nozzle is properly inserted and any manual valve on the nozzle or hose is opened (though no valve is explicitly shown being operated, it's typical for such systems). Fill the DEF tank to the desired level.

Goal: Successfully transfer DEF from the station to the vehicle.
