oil change JEEP GRAND CHEROKEE 2015 WK2 / 4.G Diesel Supplement Manual

ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.NOTE:Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.

Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the DID for five seconds after a single
chime has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator systemis duty cycle based, which means the engine oil change
interval may fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to display each
time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release the
OK button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
Oil Change Reset Procedure
1. Without pushing the brake pedal, push and release the

Diesel Particulate Filter (DPF) is self-cleaning. Main-
tain your current driving condition until regeneration
is completed.
•Exhaust System — Regeneration Completed— This
message indicates that the Diesel Particulate Filter
(DPF) self-cleaning is completed. If this message is
displayed, you will hear one chime to assist in alerting
you of this condition.
•Exhaust Service Required — See Dealer Now— This
messages indicates regeneration has been disabled due
to a system malfunction. At this point the engine
Powertrain Control Module (PCM) will register a fault
code, the instrument panel will display a MIL light.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.•Exhaust Filter Full — Power Reduced See Dealer—
This message indicates the PCM has derated the
engine to limit the likelihood of permanent damage to
the after-treatment system. If this condition is not
corrected and a dealer service is not performed, exten-
sive exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have your
vehicle serviced by your local authorized dealer.
NOTE:Failing to follow the oil change indicator, chang-
ing your oil and resetting the oil change indicator by 0
miles remaining will prevent the diesel exhaust filter
from performing it’s cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized dealer will be
able to correct this condition.

Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
•sudden loss of power
•unusual engine noises
•fuel, oil or coolant leaks
•sudden change, outside the normal operating range, in
the engine operating temperature
•excessive smoke
•oil pressure drop
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground-fault interrupter protected 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
Its use is recommended for environments that routinely
fall below -10°F (-23°C). It should be used when the
vehicle has not been running for long periods of time and
should be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under -20°F
(-28°C).
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.

STARTING AND OPERATING 45

Biodiesel Fuel Requirements
A maximum blend of 5% biodiesel meeting ASTM speci-
fication D975 is recommended for use with your diesel
engine. If frequent operation with Biodiesel blends that
are between 6% and 20% (B6–B20) is desired, the main-
tenance schedule is subject to shorter intervals.
The oil and filter change along with fuel filter replace-
ment is subject to shorter intervals when operating your
engine on biodiesel greater than 5%. Do not use biodiesel
greater than 20%.
For regular use of biodiesel blends between 6% and 20%
(B6–B20) it is important that you understand and comply
with these requirements. Refer to the “Maintenance
Chart” in the “Maintenance Schedules” section for fur-
ther direction.
CAUTION!
Failure to comply with Oil Change requirements for
vehicles operating on biodiesel blends between 6%
and 20% (B6–B20) will result in premature engine
wear. Such wear is not covered by the New Vehicle
Limited Warranty.
Biodiesel is a fuel produced from renewable resources
typically derived from animal fat, rapeseed oil (Rapeseed
Methyl Ester (RME) base), or soybean oil (Soy Methyl
Ester (SME or SOME) base).
Biodiesel fuel has inherent limitations which require that
you understand and adhere to the following require-
ments if you use blends of Biodiesel between 6% and 20%
(B6–B20). There are no unique restrictions for the use of
B5.
48 STARTING AND OPERATING

Fuel Water Separation — Must Use MOPAR
Approved Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your MOPAR filtration
system is designed to provide adequate fuel water sepa-
ration capabilities.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change Interval
Fuel dilution of lubricating oil has been observed with
the use of Biodiesel fuel. Fuel in oil must not exceed 5%.
To ensure this limit is met your oil change interval must
be maintained with in the suggested schedule. The
regular use of biodiesel between 6% and 20% requires
intervals shorter than the outlined 10,000 miles and must
not exceed the suggested schedule. When routinely op-
erating on biodiesel between 6% and 20%, oil and filter
replacement intervals must not exceed 8,000 Miles or 6
months, which ever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biodiesel requires intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the 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 ex-
ceed 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 bio-
diesel higher than 20%.

mark. The total capacity from the MIN mark to the MAX
mark is 1.7 qts (1.6L).
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,5

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.
78 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Driver Informa-
tion Display (DID)” in “Understanding Your Instrument
Panel” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
