2021 JEEP GRAND CHEROKEE warning lights

CAUTION!
For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications. The use of other
products or mixtures may damage the en-
gine beyond repair and consequently void
the warranty, due to the damage caused. If
you accidentally introduce other types of
fuel into the tank, do not start the engine.
Empty the tank. If the engine has been run
for even an extremely limited amount of
time, you must not only drain the fuel
tank, but the rest of the supply circuit as
well.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuel
filter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” in your Owner’s Manual for further
information.
AdBlue® (UREA) — If Equipped
The vehicle is equipped with an UREA injec-
tion system and Selective Catalytic Reduc-
tion to meet emission standards. These two
systems ensure compliance with the diesel
emissions requirements; at the same, they
ensure fuel-efficiency, handling, torque and
power. For messages and system warnings,
refer to the "Warning Lights And Messages" in
the "Getting To Know Your Instrument Panel"
section. AdBlue
®is a very stable product
with a long shelf life. Stored at temperatures
LOWER than 90 °F (32 °C), it has a shelf life
of at least one year. For more information on
the AdBlue
®liquid type, see the “Fluids and
lubricants” in the “Technical specifications”
section. The vehicle is equipped with an
automatic AdBlue
®heating system when the
engine starts allowing the system to work
correctly at temperatures lower than 12 °F
(-11 °C).
NOTE:
• AdBlue
®freezes at temperatures lower
than 12 °F (-11 °C).• Your vehicle is equipped with a AdBlue
®
injection system. You may occasionally
hear an audible clicking noise from under
the vehicle at a stop. This is normal opera-
tion.
• The AdBlue
®pump will run for a period of
time after engine shutdown to purge the
AdBlue
®system. This is normal operation
and may be audible from the rear of the
vehicle.
AdBlue® Storage
AdBlue®is considered a very stable product
with a long shelf life. If AdBlue®is kept in
temperatures between 10° and 90°F
(-12° and 32°C), it will last a minimum of
one year.
AdBlue
®is subject to freezing at the lowest
temperatures. For example, AdBlue®may
freeze at temperatures at or below 12° F
(-11° C). The system has been designed to
operate in this environment.
STARTING AND OPERATING
190

NOTE:
When working with AdBlue®, it is important
to know that:
• Any containers or parts that come into con-
tact with AdBlue
®must be AdBlue®com-
patible (plastic or stainless steel). Copper,
brass, aluminum, iron or non-stainless
steel should be avoided as they are subject
to corrosion by AdBlue
®.
• If AdBlue
®is spilled, it should be wiped up
completely.
Adding AdBlue®
Preliminary Conditions
AdBlue
®freezes at temperatures lower than
12° F (-11° C). If the car stands for a long
time at this temperature refilling could be
difficult. For this reason, it is advised to park
the vehicle in a garage and/or heated environ-
ment and wait for the urea to return to liquid
state before topping up.Proceed as follows:
• Park the car on flat ground and stop the
engine by cycling the ignition to the OFF
position.
• Open the fuel door, undo and remove the
cap (blue) from the AdBlue
®filler.Refilling With Nozzles
You can fill up at any AdBlue
®distributor.
Proceed as follows:
• Insert the AdBlue
®nozzle in the filler, start
refilling and stop refilling at the first shut-
off (the shut-off indicates that the AdBlue
®
tank is full). Do not proceed with the refill-
ing, to prevent spillage of AdBlue®.
• Extract the nozzle.
Refilling With Containers
Proceed as follows:
• Check the expiration date.
• Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue
®tank.
• If systems which cannot be screwed in (e.g.
tanks) are used for refilling, after the indi-
cation appears on the instrument panel
display refer to “Warning lights And Mes-
sages" in the “Getting To Know Your Instru-
ment Panel” for further information, fill the
AdBlue
®tank with no more than 5.8 Gal-
lons (22 liters).
Fuel Filler
1 — Fuel Filler
2 — AdBlue®Filler Cap
191

• If containers which can be screwed to the
filler are used, the reservoir is full when the
AdBlue
®level in the container stops pour-
ing out. Do not proceed further.
CAUTION!
To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
Operations After Refilling
Proceed as follows:
• Fit the cap back on the AdBlue
®filler by
turning it clockwise and screwing it com-
pletely.
• Cycle the ignition to RUN (it is not neces-
sary to start the engine).
• Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few sec-
onds to approximately half a minute. If the
engine is started and the car is moved, the
indication will remain on for longer. This
will not compromise engine operation.• If the AdBlue
®was topped up when the
tank was empty, wait for 2 minutes before
starting the engine.
NOTE:
• If AdBlue
®is spilled out of the filler neck,
clean up well the area and proceed to filling
up again. If the liquid crystallizes, elimi-
nate it with a sponge and warm water.
• DO NOT EXCEED THE MAXIMUM LEVEL:
this could cause damage to the reservoir.
AdBlue
®freezes at under 12° F (-11° C).
Although the system is designed to operate
below the freezing point of the AdBlue
®,it
is advisable not to fill the tank beyond the
maximum level because if the AdBlue
®
freezes the system can be damaged. Follow
the instructions in this section.
• If the AdBlue
®is spilled on painted sur-
faces or aluminium, immediately clean the
area with water and use absorbent material
to collect the fluid that has been spilled on
the ground.
• Do not try to start the engine if AdBlue
®
was accidentally added to the diesel fuel
tank, this can result in serious engine dam-
age, contact an authorized dealer.• Do not add additives or other fluids to
AdBlue
®, doing so could damage the
system.
• The use of non-conforming or degraded
AdBlue
®may lead to indications appearing
on the instrument panel display refer to
“Warning Lights And Messages" in the
“Getting To Know Your Instrument Panel”
for further information.
• Never pour AdBlue
®into another con-
tainer: it could be contaminated.
• If the AdBlue
®runs out, see refer to “Warn-
ing Lights And Messages" in the “Getting To
Know Your Instrument Panel” for further
information to continue using the car
normally.
