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 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 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
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 ADD mark to the Full
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.
Change Engine Oil
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 FCA LLC. Use MOPAR or an
equivalent oil meeting FCA Material Standard MS-10902.
Products meeting Cummins CES 20081 may also be used.
The identification of these engine oils are typically lo-
cated 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.

MAINTAINING YOUR VEHICLE 337

Oils with a high ash content may produce damaging
deposits on cylinder head 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.
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 MaterialStandard 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 use
syntheticengine 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.
338 MAINTAINING YOUR VEHICLE

Engine oil not designated by the FCA or Cummins
Material Standards and API CJ-4 should not be used, asengine 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.
340 MAINTAINING YOUR VEHICLE

The condition of the air cleaner filter is monitored by the
Engine Control Module. The “SERVICE AIR FILTER”
message will display in the Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID)
when service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
The “SERVICE AIR FILTER” message could be displayed
periodically. This is because engine air flow requirements
change based on driving conditions. As the filter becomes
more restrictive and air flow requirements increase the
“SERVICE AIR FILTER” message will be displayed. The
message may not be displayed in subsequent drive cycles
if the same conditions are not met. The air filter element
should be replaced within 250 miles (402 km) from the
first time this message is displayed to ensure proper
engine operation during all driving conditions.CAUTION!
Driving with a restricted air filter can cause engine
damage. Driving in dusty environments for extended
periods will lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE AIR
FILTER” message is displayed.
If the vehicle experiences a sudden loss of engine power
while being driven in heavy snow or rain, or when
plowing snow, and/or the “SERVICE AIR FILTER” mes-
sage is displayed on the EVIC/DID along with a chime
that repeats every 60 seconds, visually inspect the air
filter for snow/ice build up or extreme water saturation.
If the air filter is not damaged, remove all snow/ice and
reinstall air filter. If the air filter is damaged, replace filter
element.
