
At 40°F (4°C) you could see some increase in the DEF
gauge due to the tank thawing. The gauge and level
sensor are working properly and are just updating with
proper thawed DEF.

Excessive overfilling of the DEF tank can result in a MIL
lamp/fault code and inaccurate level readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:

Insert the DEF nozzle in the filler tube, start refilling and
stop refilling at the first shut-off (the shut-off indicates
that the DEF tank is full). DO NOT proceed with the
refilling, to prevent spillage of DEF.
 Extract the nozzle.
Refilling With Containers
Proceed as follows:

Check the expiration date.
 Read the advice for use on the label before pouring the
content of the bottle into the DEF tank.
 After the indication appears on the instrument cluster
display
Ú
page 104 fill the DEF tank with no more than
4 gallons (15 liters).
Stop filling the DEF tank immediately if DEF splashes or
wells back in the filler neck.
Reinstall cap onto DEF filler tube.
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 injection system to operate
properly at temperatures 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 cluster. You may safely add a
maximum of 2 gallons (7.5 liters) of DEF from portable
containers when your DEF gauge is reading ½ full.

(GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
P
AYLOAD
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
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 acciden -
tally 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.

Never add anything other than DEF to the tank –
especially any form of hydrocarbon 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 contaminate 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
has only been used for adding DEF. Mopar® provides
an attachable nozzle with its DEF for this purpose.
CAUTION!
