DEF Fill Procedure
NOTE: Refer to "Fluids And Lubricants" in the "Technical
Specifications" section for the correct fluid type.
1. Remove cap from DEF fill inlet (located in fuel door).
Fuel and Diesel Exhaust Fluid Fill Location
1 — Diesel Fuel Filler
2 — Diesel Exhaust Fluid Filler
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.
CAUTION!
• To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not "top off" the DEF
tank after filling.
