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.

CAUTION!(Continued)
•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 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.
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 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 tempera-
tures 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. On pickup applications,
you may safely add a maximum of 2 gallons of DEF from
portable containers when your DEF gauge is reading ½ full.

mark. The total capacity from the MIN mark to the MAX
mark is 1.3 qts (1.2 L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE:It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.

Only use ACEA C3 SAE 5W-30 Synthetic Low Ash engine
oil meeting FCA US Material Standard MS-11106 or
Pennzoil Ultra Euro L full synthetic 5W-30 motor oil,
which is recommended for all operating temperatures.
This engine oil improves low temperature starting and
vehicle fuel economy.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Engine Oil Filter
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information. The
engine oil filter should be changed at every engine oil
change.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
104 MAINTAINING YOUR VEHICLE
Page 107 of 360

WARNING!
The air induction system (air cleaner, hoses, etc.)
provides a measure of protection. Do not remove the
air induction system (air cleaner, hoses, etc.) unless
such removal is necessary for repair or maintenance.
Make sure that no one is near the engine compart-
ment before starting the vehicle with the air induc-
tion system (air cleaner, hoses, etc.) removed. Failure
to do so can result in serious personal injury.
CAUTION!
Many aftermarket performance air filter elements do
not adequately filter the air entering the engine. Use
of such filters can severely damage your engine.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR® engine air
cleaner filters are a high quality filter and are recom-
mended.
Draining Fuel/Water Separator Filter
The fuel filter/water separator filter housing is located
above the rear axle next to the fuel tank. The best access
to this water drain valve is from under the vehicle.5
MAINTAINING YOUR VEHICLE 105
Page 108 of 360
CAUTION!
•Do not drain the fuel/water separator filters when
the engine is running.
•Diesel fuel will damage blacktop paving surfaces.
Drain the filters into an appropriate container.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in the
ON position, the “Water In Fuel Indicator Light” will
illuminate and an audible chime will be heard. At this
point you should stop the engine and drain the water
from the filter housing.

Page 109 of 360

CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a
single chime is heard while you are driving, or with the
ignition in the ON position, there may be a problem with
your water separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from the fuel filter, the
“Water In Fuel Indicator Light” will remain illuminated
for approximately 10 seconds. If the water was drained
while the engine was running, the “Water In Fuel Indi-
cator Light” may remain on for approximately three
minutes.NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact an authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain the fuel/water separator filter when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON
position, and allow any accumulated water to drain.
Leave the drain valve open until all water and contami-
nants have been removed. When clean fuel is visible,
close the drain valve by turning it clockwise, and turn the
ignition switch to OFF.
