2014 JEEP GRAND CHEROKEE engine

Only use ACEA C3 SAE 5W-30 Synthetic Low Ash engine
oil meeting Chrysler material standard MS-11106 or
Pennzoil Ultra Euro L full synthetic 5W-30 motor oil,
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.
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.
(Continued)
WARNING!(Continued)
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.
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.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
assure most efficient service. MOPAR® engine air cleaner
filters are a high quality filter and are recommended.

Draining Fuel/Water Separator Filter
The fuel filter/water separator housing is located on the
left side of the vehicle in front of the fuel tank. The best
access to this water drain valve is from under the vehicle.
CAUTION!
•Do not drain the fuel/water separator filters when
the engine is running.
• Diesel fuel will damage blacktop paving surfaces.
Drain the filters 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. At this
point you should stop the engine and drain the water
from the filter housing.

78 MAINTAINING YOUR VEHICLE

CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a
single chime are heard while you are driving, or with the
ignition in the ON position, there may be a problem with
your water separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from fuel filter
assembly, the “Water In Fuel Indicator Light” will remain
illuminated for approximately 10 seconds. If the water
was drained while the engine was running, the “Water In
Fuel Indicator Light” may remain on for approximately
three minutes. NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact an authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain the fuel/water separator filters when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON
position, and allow any accumulated water to drain.
Leave the drain valve open until all water and contami-
nants have been removed. When clean fuel is visible,
close the drain valve by turning it clockwise, and turn the
ignition switch to OFF.

If more than two ounces or 60 milliliters of fuel have been
drained, follow the directions for “Priming If The Engine
Has Run Out Of Fuel.”
Underbody Mounted Fuel Filter Replacement
NOTE:Using a fuel filter that does not meet the manu-
facturer’s filtration and water separating requirements
can severely impact fuel system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate container.
• 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.

3. Open the water drain valve, and let any accumulatedwater drain.
4. Close the water drain valve.
5. Remove using a socket. 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. Repeat steps 5 through 8 to service second filter in fuel filter assembly.
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).
2. Press ignition switch twice without your foot on brake to put vehicle in Run position. This will activate the in
tank fuel pump for approximately 30 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.

CAUTION!
The starter motor will engage for approximately
30 seconds at a time. Allow two minutes between the
cranking intervals.
NOTE: The engine may run rough until the air is forced
from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.
NOTE:
• We recommend you use a blend of up to 5% biodiesel,
that meets ASTM specification D-975 with your diesel
engine. Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter’s ability to separate
water from the fuel, resulting in high pressure fuel
system corrosion or damage.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your diesel
engine.

Intervention Regeneration Strategy — EVIC
Message Process Flow
This engine meets all required diesel engine emissions
standards. To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine and
exhaust system. These systems are seamlessly integrated
into your vehicle and managed by the Powertrain Con-
trol Module (PCM). The PCM manages engine combus-
tion to allow the exhaust system’s catalyst to trap and
burn Particulate Matter (PM) pollutants, with no input or
interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your vehicle or engine.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
