Low Diesel Emissions Additive Ad-
Blue (UREA) Level WarningThe first low level warning will be given at around a 1490 miles (2400 km) range, and is determined accord-
ing to the current consumption rate. The “UREA Low Level” warning light and message will display on the
instrument panel. The UREA low level warning light will remains lit until the AdBlue (UREA) tank is topped
up with at least 1.32 gallons (5 Liters) of UREA.
If the level is not resolved, an additional warning appear whenever a certain threshold is reached until it will
no longer be possible to start the engine.
When 125 miles (200 km) are remaining before the AdBlue (UREA) tank is empty, a message will appear on
the instrument panel, accompanied by a buzzer sound. When the range is at 0, the display will show a dedi-
cated message (if equipped). In this case, the engine will not restart.
It will be possible to restart the engine again as soon as AdBlue (UREA) is added; the minimum amount re-
quired is 1.32 gallons (5 Liters). Fill the AdBlue (UREA) tank as soon as possible with at least 1.32 gallons
(5 Liters) of UREA. If filling is completed with autonomy tank AdBlue (UREA) to zero, it could be possible to
wait 2 minutes before starting the vehicle.
NOTE:
When the AdBlue (UREA) tank is empty, and the vehicle is stopped, it is no longer possible to restart the

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 run-
ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.
WARNING!
• Do not apply any object/cap to the end of
the filler which is not provided for the
car. The use of non-compliant objects/
plugs could cause a pressure increase
inside the tank, resulting in dangerous
situations.
• 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.
CAUTION!
• Damage to the fuel system or emission
control system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.NOTE:
• When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
• Tighten the fuel filler cap about 1/4 turn
until you hear one click. This is an indica-
tion that the cap is properly tightened.
• If the fuel filler cap is not tightened prop-
erly, the MIL will come on. Be sure the cap
is tightened every time the vehicle is
refueled.
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 (UREA) is a very stable prod-
uct with a long shelf life. Stored at tempera-
tures LOWER than 90 °F (32 °C), it has a
shelf life of at least one year. For more infor-
mation on the AdBlue liquid type, see the
Fuel and AdBlue (UREA) Fill Location

“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.
