2016 JEEP GRAND CHEROKEE Diesel Supplement Manual

3. Insert the fuel nozzle fully into the filler pipe – thenozzle 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. 2. Insert funnel into same filler pipe opening as the fuel
nozzle.

STARTING AND OPERATING 63

NOTE:Ensure funnel is inserted fully to hold flapper
door open.
3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior to putting back in the spare tire kit.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.

Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system. If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
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.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
4
STARTING AND OPERATING 65

DEF is subject to freezing at the lowest temperatures.
For example, DEF may freeze at temperatures at or below
12° F (-11° C). The system has been designed to operate in
this environment.
NOTE:When working with DEF, it is important to know
that:
• Any containers or parts that come into contact with
DEF must be DEF compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or non-stainless
steel should be avoided as they are subject to corrosion
by DEF.
• If DEF is spilled, it should be wiped up completely.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).

2 — Diesel Exhaust Fluid Fill Location
2. Insert DEF fill adapter/nozzle into DEF fill inlet. NOTE:
•The DEF gauge may take up to five seconds to
update after adding a gallon or more of Diesel
Exhaust Fluid (DEF) to the DEF tank. If you have a
fault related to the DEF system, the gauge may not
update to the new level. See your authorized dealer
for service.
• The DEF gauge may also not immediately update
after a refill if the temperature of the DEF fluid is
below 12F (-11C). The DEF line heater will possibly
warm up the DEF fluid and allow the gauge to
update after a period of run time. Under very cold
conditions, it is possible that the gauge may not
reflect the new fill level for several drives.

CAUTION!
•To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
• DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
• When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.
• Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
(Continued)
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.
