2015 JEEP GRAND CHEROKEE fuel cap

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%.
50 STARTING AND OPERATING

1 — Fuel Fill Location
2 — Diesel Exhaust Fluid Fill Location
NOTE:There is no fuel filler cap. A flapper door inside
the filler pipe seals the system.3. Insert the fuel nozzle fully into the filler pipe – the
nozzle opens and holds the flapper door while refuel-
ing.
4. Fill the vehicle with fuel – when the fuel nozzle
“clicks” or shuts off the fuel tank is full.
5. Remove the fuel nozzle and close the fuel door.
Emergency Fuel Can Refueling
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to allow
emergency refueling with a fuel can.
1. Retrieve funnel from the spare tire kit.

Adding Diesel Exhaust Fluid
The DEF gauge (located on the Driver Information Dis-
play (DID display) will display the level of DEF remain-
ing in the tank. Refer to “Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for
further information.
NOTE:Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in your
vehicle.
DEF Fill Procedure
NOTE:Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF fill inlet (located in fuel door).

CAUTION!(Continued)
•Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel
fuel, fuel system additives, gasoline, or any other
petroleum-based product. Even a very small
amount of these (less than 100 parts per million or
less than 1 oz. per 78 gallons) will contaminate the
entire DEF system and will require replacement. If
owners use a container, funnel or nozzle when
refilling the tank, it should either be new or one
that is has only been used for adding DEF. MOPAR
provides an attachable nozzle with its DEF for this
purpose.3. Stop filling the DEF tank immediately when any of the
following happen: DEF stops flowing from the fill
bottle into the DEF fill inlet, DEF splashes out the fill
inlet, or a DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF fill inlet.

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

Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air
rapidly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through
another hose to the intake manifold of the engine. This
cooling process enables more efficient burning of fuel
resulting in fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and
radiator clean and free of debris. Periodically check the
hoses leading to and from the charge air cooler for cracks
or loose clamps resulting in loss of pressure and reduced
engine performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
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.
