Diesel Particulate Filter (DPF) Messages
— If Equipped
This engine meets all required diesel engine
emissions standards. To achieve these emis-
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte-
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the ex-
haust system’s catalyst to trap and burn Par-
ticulate Matter (PM) pollutants, with no input
or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
WARNING!
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. Refer to the following mes-
sages that may be displayed on your instru-
ment cluster display:
•Exhaust Filter Nearing Full Safely Drive at
Highway Speeds to Clear— This message
will be displayed if the exhaust particulate
filter reaches 80% of its maximum storage
capacity. Under conditions of exclusive
short duration and low speed driving cycles,
your diesel engine and exhaust after-
treatment system may never reach the con-
ditions required to cleanse the filter to
remove the trapped PM. If this occurs, the
“Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy” message will
be displayed. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition. By simply driving yourvehicle at highway speeds for up to 20 min-
utes, you can remedy the condition in the
particulate filter system and allow your die-
sel engine and exhaust after-treatment sys-
tem to cleanse the filter to remove the
trapped PM and restore the system to nor-
mal operating condition.
•Exhaust System Regeneration in Process Con-
tinue Driving— This message indicates that
the Diesel Particulate Filter (DPF) is self-
cleaning. Maintain your current driving
condition until regeneration is completed.
•Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition.
•Exhaust System Service Required — See
Dealer— This messages indicates regen-
eration has been disabled due to a system
malfunction. At this point the engine Pow-
ertrain Control Module (PCM) will register a
fault code, the instrument panel will dis-
play a MIL light.

— Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced by an authorized dealer as
soon as possible if this occurs.WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— AdBlue® (UREA) Injection System
Failure Warning Light — If Equipped
This warning light will illuminate along with a
dedicated message on the display (If
Equipped) if an unknown fluid not conform-
ing with acceptable characteristics is in-
serted, or if an average consumption of
AdBlue
®(UREA) over 50% is detected. Con-
tact an authorized dealer as soon as possible.
If the problem is not solved, a specific mes-
sage will appear on the Instrument Cluster
Display whenever a certain threshold is
reached until it will no longer be possible to
start the engine.
When about 125 mi (200 km) are remaining

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.

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).
