1. Remove cap from DEF tank (located on
drivers side of the vehicle or in fuel door).
Fill Locations
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.
Excessive overfilling of the DEF tank can
result in a MIL lamp/fault code and inac-
curate level readings.

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, however, if the
tank is overfilled and freezes, the system
could be damaged.
When DEF is spilled, clean the area
immediately with water and use an
absorbent material to soak up the 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.
CAUTION! (Continued)
