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 per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized Chrysler Group LLC
dealership or qualified repair center.
(Continued)
CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
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 tem-
perature, then wait for 30 minutes after engine shutdown
to check the oil.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 “ADD”
mark. The total capacity from the low mark to the high
mark is 2 qts (1.9L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
Never operate the engine with oil level below the “ADD”
mark or above the upper “SAFE” mark.

Refer to the “Maintenance Schedule” for the proper
maintenance intervals.

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API CJ-4 certified and
meet the requirements of Chrysler Group LLC. Use
MOPARor an equivalent oil meeting Chrysler Material
Standard MS-10902. Products meeting Cummins CES
20081 may also be used. The identification of these
engine oils are typically located on the back of the oil
container.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American Petro-
leum Institute (API). The manufac-
turer only recommends API Certified
engine oils. Oils with a high ash content may produce damaging
deposits on engine valves and/or aftertreatment system
damage. A maximum sulfated ash content of 1.00 mass %
is recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum based oil. Also, synthetic oil
must meet the same performance specifications as petro-
leum oil.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
102 MAINTAINING YOUR VEHICLE

Engine Oil Viscosity (SAE Grade)
Use SAE 15W-40 MOPARor an equivalent engine oil
meeting Chrysler Material Standard MS-10902. Products
meeting Cummins CES 20081 may also be used. The
identification of these engine oils is typically located on
the back of the oil container.
In ambient temperatures below 0°F (-18°C), SAE 5W-40
synthetic engine oil that meets Chrysler Materials Stan-
dard MS-10902 and the API CJ-4 engine oil category is
required.
CAUTION!
Failure to use SAE 5W-40 synthetic engine oil in
ambient temperatures below 0°F (-18°C) could result
in severe engine damage. Engine oil not designated by the Chrysler or Cummins

Material Standards and API CJ-4 should not be used, as
engine and exhaust system durability may be compro-
mised. The engine oil filler cap also shows the recom-
mended engine oil viscosity for your engine. For infor-
mation on engine oil filler cap location, refer to “Engine
Compartment” in “Maintaining Your Vehicle” for further
information.

Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes or
lube odorants) to the engine oil. Engine oil is an engi-
neered product and its performance may be impaired by
supplemental additives.
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 Filter
Care should be taken in disposing of the used engine
fluids from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the environment.
Contact an authorized dealer, service station, or govern-
mental agency for advice on recycling programs and
where used fluids and filters can be safely discarded in
your area.
Engine Air Cleaner Filter
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

NOTE:The air filter housing contains a Mass Air Flow
sensor. This sensor is critical to proper engine operation
and component longevity. Any damage or modification
to this sensor could result in major engine and/or
exhaust aftertreatment damage. This includes the use of
non-approved air filters. Use only MOPAR approved air
filters or equivalent.
A visual inspection of the air cleaner filter element is
never recommended under normal circumstances. A
badly restricted element may appear clean while a soiled
element may be quite effective in filtering particles
without restricting air flow. Rely on the Engine Control
Module to determine when a filter change is necessary.
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.
Draining Fuel/Water Separator Filter
The fuel filter and water separator assembly is located on
the driver’s side of the engine. The best access to the
water drain valve is from under the hood.
CAUTION!
•Do not drain the fuel/water separator filter when
the engine is running.
•Diesel fuel will damage blacktop paving surfaces.
Drain the filter 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 five times.
At this point you should stop the engine and drain the
water from the separator.
106 MAINTAINING YOUR VEHICLE

CAUTION! (Continued)
•Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility debris could be
introduced into the fuel filter during this action. It
is best to install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn counterclockwise
and completely drain fuel and water into the approved
container.
4. Close the water drain valve.
5. Remove lid using a socket or strap wrench. Rotate
counterclockwise for removal. Remove used o-ring and
discard it. 6. Remove the used filter cartridge from the housing and
dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter
housing and lubricate with clean engine oil.
9. Remove new filter cartridge from plastic bag and
install into housing.
NOTE:
Do not remove cartridge from bag until you
reach this step in order to keep cartridge clean.
10. Push down on the cartridge to ensure it is properly
seated. Do not pre-fill the filter housing with fuel.
11. Install lid onto housing and tighten to 22.5 ft lbs
(30.5 N.m). Do not overtighten the lid.
12. Prime the engine using the procedure in “Priming If
The Engine Has Run Out Of Fuel.” Then start the engine
and confirm there are no leaks.
