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
12°F (-11°C). 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.
•
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
•
When DEF is spilled, clean the area immediately
with water or use an absorbent material to soak up
and spills on the ground.
•
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
