FUEL SYSTEM MESSAGES
The following chart contains a list of different messages that may appear in the instrument cluster, depending on different system or fuel conditions. Use the
descriptions to interpret what the message means and determine the best action to take.
MESSAGE DESCRIPTION
Diesel Emissions Additive AdBlue® (UREA) Warning Messages:
Low Diesel Emissions Additive AdBlue® (UREA) Level
Warning The first low level warning will be given at around a 1,490 miles (2,400 km) range, and is
determined according 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
remain 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 appears 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 dedicated 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 required 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 vehicle until a minimum of 1.32 gallons (5 Liters) of AdBlue® (UREA) is added
to the AdBlue® (UREA) tank.

Diesel Emissions Additive AdBlue® (UREA) Fault Warning Messages:
Engine Will Not Restart Service AdBlue® System See Dealer This message will display if the AdBlue® (UREA) system issue detected is not serviced during
the allowed period. Your engine will not restart unless your vehicle is serviced by an
authorized dealer. If the level is not resolved, an additional warning appears 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® tank is empty, a message will appear
on the instrument panel, accompanied by a buzzer sound.
Engine Will Not Start Service AdBlue® System See Dealer
NOTE:
The display may take up to five seconds to update after adding 2 gallons (7.5 Liters) or
more of AdBlue® (UREA) to the AdBlue® (UREA) tank. If you have a fault related to the
AdBlue® (UREA) system, the display may not update to the new level. See an authorized
dealer for service.
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 environment, and wait for the AdBlue® (UREA) to return
to liquid state before topping up.
Gasoline Particulate Filter (GPF) System Messages — If Equipped:
Exhaust System Service Required The engine control unit has detected an issue with the gasoline particulate filter system. See
an authorized dealer.
Exhaust System Regeneration in Process Continue Driving The regeneration procedure is controlled automatically by the engine control unit according
to the filter conditions and car use conditions. The following may occur during regeneration:
increased levels of Noise Vibration and Harshness (NVH) and reduced engine performance.
The driver should continue driving normally. This message will continue to appear until
regeneration is complete.
Exhaust System Regeneration Complete The exhaust gas filter regeneration has been completed. This message will briefly appear.

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
conforming with acceptable
characteristics is inserted, or if an average
consumption of AdBlue® (UREA) over 50% is
detected. Contact an authorized dealer as soon as
possible. If the problem is not solved, a specific message 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 miles (200 km) are remaining
before the AdBlue® (UREA) tank is empty, a
continuous dedicated message will appear on the
instrument panel, accompanied by a buzzer sound
(if equipped).
YELLOW INDICATOR LIGHTS
4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the four-wheel drive mode, and the
front and rear driveshafts are
mechanically locked together forcing the
front and rear wheels to rotate at the same speed.
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the 4WD Low mode. The front and
rear driveshafts are mechanically locked
together forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels.
4WD Part Time Indicator Light —
If Equipped
This light alerts the driver that the vehicle
is in the four-wheel drive part time mode,
and the front and rear driveshafts are
mechanically locked together forcing the
front and rear wheels to rotate at the same speed.
Axle Locker Fault Indicator Light —
If Equipped
This light indicates when front and/or
rear axle locker fault has been detected.
Rear Axle Lock Indicator Light —
If Equipped
This light indicates when the rear axle
lock has been activated Ú page 161.
Front And Rear Axle Lock Indicator Light —
If Equipped
This light indicates when the front, rear,
or both axles have been locked. The
telltale will display the lock icon on the
front and rear axles to indicate the
current lock status.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

intake manifold temperature is warm enough.
Low Diesel Exhaust Emissions Additive
AdBlue® (UREA) Indicator Light —
If Equipped
The Low Diesel Exhaust Emissions
Additive AdBlue® (UREA) indicator light
illuminates when the AdBlue® (UREA)
level is low.
Fill the AdBlue® (UREA) tank as soon as possible
with at least 1.3 gallons (5 liters) of AdBlue®
(UREA).
If filling the tank is done with a remaining range of
AdBlue® (UREA) in the tank equal to zero, you may
need to wait two minutes before starting the
vehicle.
Water In Fuel Indicator Light — If Equipped
The Water In Fuel Indicator Light will
illuminate when there is water detected
in the fuel filter. If this light remains on,
DO NOT start the vehicle before you drain
the water from the fuel filter to prevent engine
damage, and please see an authorized dealer.
GREEN INDICATOR LIGHTS
4WD Auto Indicator Light — If Equipped
This light alerts the driver that the
vehicle is in the four-wheel drive auto
mode. The system will provide power to
all four wheels and shift the power
between the front and rear axles as needed. This
will provide maximum traction in dry and slippery
conditions.
Cruise Control SET Indicator Light —
If Equipped With A Premium Instrument
Cluster
This indicator light will illuminate when
the cruise control is set to the desired
speed Ú page 173.
CAUTION!
The presence of water in the fuel system circuit
may cause severe damage to the injection
system and irregular engine operation. If the
indicator light is illuminated, contact an
authorized dealer as soon as possible to bleed
the system. If the previously mentioned
indicators come on immediately after refueling,
water or AdBlue® (UREA) have probably been
poured into the tank: switch the engine off
immediately and contact an authorized dealer.
