DEF Filler Cap And Fuel Fill 1500/2500/3500 Models
1 — Diesel Exhaust Fluid Fill Location
2 — Fuel Fill Location
2. Insert DEF fill adapter/nozzle into DEF tank filler
neck.
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.
