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).
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.
Exhaust Service Required — See Dealer Now
This message indicates regeneration has been disabled due to a system malfunction.
The Powertrain control Module (PCM) will register a fault code and the instrument
panel will display the Malfunction Indicator Light (MIL).
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur soon
with continued operation.

Adding Diesel Exhaust Fluid
• The DEF gauge (located in the instrument panel) will display the level of DEFremaining 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:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the amount of DEF that is used in your vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an automatic DEF heating system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it could be damaged.
Therefore, do not overfill the DEF tank. Extra care should be taken when filling
with portable containers to avoid overfilling. Note the level of the DEF gauge in
your instrument cluster. On pickup applications, you may safely add a maximum of
2 gallons of DEF from portable containers when your DEF gauge is reading ½ full.
DEF Fill Procedure
• Remove cap from DEF tank (located behind the fuel door on drivers side of thevehicle).
• Insert DEF container or fill nozzle into DEF fill location and fill DEF tank.
NOTE:
•
The DEF gauge may take up to five
seconds to update after adding a gal-
lon 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 authorized 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
possibly 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.
• Reinstall cap onto DEF tank.
• Refer to your Diesel Supplement on the DVD for further details.
