suggested schedule. When operating on biodiesel between
6% and 20%, fuel filter replacement intervals must not
exceed 20,000 Miles (40,233 km).
NOTE:Under no circumstances should oil change inter-
vals exceed 8,000 miles (12,875 km) or 6 months, if regular
operation occurs with 6% - 20% biodiesel blends. Under no
circumstances should fuel filter intervals exceed 20,000
miles (40,233 km), if regular operation occurs with 6% -
20% biodiesel blends. Failure to comply with these Oil
Change and fuel filter requirements for vehicles operating
on biodiesel blends up to B20 may result in premature
engine wear. Such wear is not covered by the New Vehicle
Limited Warranty. The engine may suffer severe damage if
operated with concentrations of biodiesel higher than 20%.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Reduc-
tion system to meet the very stringent diesel emissions
standards required by the Environmental Protection
Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harmful
to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected into the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides
(NOx) into harmless nitrogen (N2) and water vapor (H2O),
two natural components of the air we breathe. You can
operate with the comfort that your vehicle is contributing
to a cleaner, healthier world environment for this and
generations to come.
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF)
injection system and a Selective Catalytic Reduction (SCR)
catalyst to meet the emission requirements.
The DEF injection system consists of the following compo-
nents:
•
DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealership or qualified repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
(Continued)
CAUTION! (Continued)
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified fluid
for the flushing procedure.
Engine Oil
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer recom-
mends engine oils that meet the requirements of FCA
Material Standard MS-10902, and that are API CJ-4 certified
and meet the requirements of FCA LLC.
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check the
oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tempera-
ture, then wait for five minutes after engine shutdown to
check the oil.

1 — MAX Mark
2 — MIN Mark
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil only
when the level on the dipstick is below the “MIN” 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 main-
tenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technology
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.
We recommend you use 5W-40 syntheticengine oil such as
MOPAR or Shell Rotella that meets FCA Material Standard
MS-10902 and the API CJ-4 engine oil category is required.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion 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 additives.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining 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 sta-
tion 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
WARNING!
The air induction system (air cleaner, hoses, etc.) pro-
vides 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 compartment before
starting the vehicle with the air induction system (air
cleaner, hoses, etc.) removed. Failure to do so can result
in serious personal injury.
CAUTION!
All air entering the engine intake must be filtered. The
abrasive particles in unfiltered air will cause rapid
wear to engine components.
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.

1 — Water in Fuel Drain
2 — Fuel Filter Access
1. Turn engine off.
2. Place a drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve. 5. Remove bottom cover using a strap wrench. Rotate
counterclockwise for removal. Remove the used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and dispose of it according to your local regulations.
7. Wipe the sealing surfaces of the lid and housing clean.
8. Install a new o-ring into the ring groove on the filter housing and lubricate with clean engine oil.
NOTE: WIF (Water In Fuel) sensor is re-usable. Service kit
comes with new o-ring for filter canister and WIF sensor.
Priming If The Engine Has Run Out Of Fuel
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).

WARNING!(Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a accident.
(Continued)
WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in an accident.
