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.
Engine Oil Viscosity (SAE Grade)
In ambient temperatures above 0°F (-18°C), we recom-
mend you use SAE 15W-40 engine oil such as MOPAR,
Shell Rotella and Shell Rimula that meets FCA Material
Standard MS-10902 and the API CJ-4 engine oil category
is required. 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
we recommend you usesyntheticengine oil such as
MOPAR, Shell Rotella and Shell Rimula that meets FCA
Material Standard 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 FCA 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 if the recommended oil
quality requirements are met and the recommended
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) 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
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
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.

5. Remove lid using a socket or strap wrench. Rotatecounterclockwise 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.
Underbody Mounted Fuel Filter Replacement
NOTE:
•Using a fuel filter that does not meet the manufactur-
er’s filtration and water separating requirements can
severely impact fuel system life and reliability.
• The underbody mounted filter housing will cause the
engine not to run if:
1. No filter is installed.

5. Remove lid using a socket or strap wrench. Rotatecounterclockwise 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.
NOTE: WIF 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).
2. Turn ignition switch to the start position to engage starter for one second, return ignition switch to run
position. This will activate in tank fuel pump for
approximately 15 seconds. Repeat this process twice.
3. Start the engine using the “Normal Starting” proce- dure. Refer to “Starting Procedures” in “Starting and
Operating” for further information.

With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your vehicle
is also identified on the original factory installed
hydraulic master cylinder reservoir.
(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder 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 pro-
longed braking, resulting in sudden brake failure.
This could result in a accident.
• 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.

5. Place the shift lever momentarily into each gear posi-tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated. 7. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill.Use
ONLY the specified fluid (see Fluids, Lubricants, and
Genuine Parts for fluid specifications). After adding
any quantity of oil through the dipstick tube, wait a
minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
