engine JEEP WRANGLER UNLIMITED 2019 Owner handbook (in English)

“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).
AdBlue (UREA) Storage
AdBlue (UREA) is considered a very stable
product with a long shelf life. If AdBlue
(UREA) is kept in temperatures between
10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue
(UREA) 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 AdBlue (UREA), it is
important to know that:
• Any containers or parts that come into con-
tact with AdBlue (UREA) must be AdBlue
(UREA) compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or
non-stainless steel should be avoided as
they are subject to corrosion by AdBlue
(UREA).
• If AdBlue (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue (UREA)
Preliminary Conditions
AdBlue (UREA) 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
environment 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 (UREA) filler.
Refilling With Nozzles
You can fill up at any AdBlue (UREA) dis-
tributor.
Proceed as follows:
• Insert the AdBlue (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that the
AdBlue (UREA) tank is full). Do not pro-
ceed with the refilling, to prevent spillage
of AdBlue (UREA).
• 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 (UREA) 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-
169

ment Panel” for further information, fill the
AdBlue (UREA) tank with no more than
2 Gallons (8 liters).
• If containers which can be screwed to the
filler are used, the reservoir is full when the
AdBlue (UREA) level in the container stops
pouring out. Do not proceed further.
Operations After Refilling
Proceed as follows:
• Fit the cap back on the AdBlue (UREA)
filler by turning it clockwise and screwing it
completely.
• 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 (UREA) was topped up when
the tank was empty, wait for 2 minutes
before starting the engine.
NOTE:
• If AdBlue (UREA) is spilled out of the filler
neck, clean up well the area and proceed to
filling up again. If the liquid crystallizes,
eliminate it with a sponge and warm water.
• DO NOT EXCEED THE MAXIMUM LEVEL:
this could cause damage to the reservoir.
AdBlue (UREA) freezes at under 12° F
(-11° C). Although the system is designed
to operate below the freezing point of the
UREA, it is advisable not to fill the tank
beyond the maximum level because if the
UREA freezes the system can be damaged.
Follow the instructions in this section.
• If the AdBlue (UREA) is spilled on painted
surfaces or aluminium, immediately clean
the area with water and use absorbent ma-
terial to collect the fluid that has been
spilled on the ground.• Do not try to start the engine if AdBlue
(UREA) was accidentally added to the die-
sel fuel tank, this can result in serious
engine damage, contact an authorized
dealer.
• Do not add additives or other fluids to
AdBlue (UREA), doing so could damage the
system.
• The use of non-conforming or degraded
AdBlue (UREA) 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 (UREA) into another
container: it could be contaminated.
• If the AdBlue (UREA) runs out, see refer to
“Warning Lights And Messages" in the
“Getting To Know Your Instrument Panel”
for further information to continue using
the car normally.
