2 — Diesel Exhaust Fluid Fill Location
2. Insert DEF fill adapter/nozzle into DEF fill inlet.
NOTE:
• The DEF gauge may take up to five seconds to
update after adding a gallon or more of Diesel
Exhaust Fluid (DEF) to the DEF tank. If you have a
fault related to the DEF system, the gauge may not
update to the new level. See your authorized dealer
for service.
• The DEF gauge may also not immediately update
after a refill if the temperature of the DEF fluid is
below 12F (-11C). The DEF line heater will possibly
warm up the DEF fluid and allow the gauge to
update after a period of run time. Under very cold
conditions, it is possible that the gauge may not
reflect the new fill level for several drives.
