CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an
appropriate container.
•
Do not prefill the fuel filter when installing a new fuel filter. There is a possibility
debris could be introduced into the fuel filter during this action. It is best to install
the filter dry and allow the in-tank lift pump to prime the fuel system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
This engine meets all required EPA diesel engine emissions standards. To achieve
these emissions standards, your vehicle is equipped with a state-of-the-art engine
and exhaust system. These systems are seamlessly integrated into your vehicle and
managed by the Powertrain Control Module (PCM). Additionally, your vehicle has the
ability to alert you to additional maintenance required on your vehicle or engine.
Refer to the following messages that may be displayed on your Electronic Vehicle
Information Center (EVIC).
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”.
When the “Perform Service” message is displayed on the EVIC it is necessary to have
the emissions maintenance performed.
Exhaust System — Regeneration Required Now
This message Indicates that the Diesel Particulate Filter (DPF) reached 80% of its
maximum storage capacity.
By simply driving your vehicle at highway speeds for up to 20 minutes, you can
remedy the condition in the particulate filter system and allow your diesel engine and
exhaust after-treatment system to cleanse the filter to remove the trapped PM and
restore the system to normal operating condition.
Exhaust System — Regeneration in Process Exhaust Filter XX% Full
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.

System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst enable the achievement of diesel
emissions requirements; while maintaining outstanding fuel economy, drivability,
torque and power ratings.
NOTE:
• Your vehicle is equipped with a DEF injection system. You may occasionally hear
an audible clicking noise. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation.
Adding Diesel Exhaust Fluid
The DEF gauge (located in the EVIC) will display the level of DEF remaining in the tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC).
NOTE:
• The gauge may take up to five seconds
to update after adding a gallon or more
of Diesel Exhaust Fluid (DEF) to the
DEF tank. If you have a fault related to
the DEF system, the gauge may not
update to the new level. See your au-
thorized dealer for service.
• The DEF gauge may also not immedi-
ately update after a refill if the tem-
perature of the DEF fluid is below 12°F
(-11°C). The DEF line heater will pos-
sibly warm up the DEF fluid and allow
the gauge to update after a period of
run time. Under very cold conditions, it is possible that the gauge may not reflect
the new fill level for several drives.
