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 immedi-
ately update after a refill if the tempera-
ture of the DEF fluid is below 12F
(-11C). The DEF line heater will possi-
bly 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 dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be-
low 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.
CAUTION!
• When DEF is spilled, clean the area
immediately with water and use an ab-
sorbent 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 dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
• Never add anything other than DEF to
the tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives,
gasoline,
or
any
other
petroleum-based product. Even a very
small
amount
of
these,
less
than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose.
3. Stop filling the DEF tank immediately
when any of the following happen: DEF
stops flowing from the fill bottle into the
DEF tank, DEF splashes out the filler
neck, or a DEF pump nozzle automatically
shuts off.
4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C),
your vehicle is equipped with an automatic
DEF heating system. This allows the DEF in-
jection system to operate properly at tempera-
tures below 12°F (-11°C). If your vehicle is not
in operation for an extended period of time with
temperatures below 12°F (-11°C), the DEF in
the tank may freeze. If the tank is overfilled
and freezes, it could be damaged. Therefore,
do not overfill the DEF tank.
Extra care should be taken when filling with
portable containers to avoid overfilling. Note the
level of the DEF gauge in your instrument clus-
ter. You may safely add a maximum of 2 gallons
(7.6 Liters) of DEF from portable containers
when your DEF gauge is reading ½ full.
