time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release the
OK button. To reset the oil change indicator system (after

Diesel Particulate Filter (DPF) Messages
This engine meets all required 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 Con-
trol Module (PCM). The PCM manages engine combus-
tion to allow the exhaust system’s catalyst to trap and
burn Particulate 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 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 vehicle or engine. Refer to
the following messages that may be displayed on your
Driver Information Display (DID):
•Exhaust Filter Nearing Full Safely Drive at Highway
Speeds to Clear — This message will be displayed on
the Driver Information Display (DID) 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
conditions 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 in the DID. If this message
is displayed, you will hear one chime to assist in
alerting you of this condition. 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 Continue
Driving — This message indicates that the Diesel
Particulate Filter (DPF) is self-cleaning. Maintain your
current driving condition until regeneration is com-
pleted.
• 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.
24 UNDERSTANDING YOUR INSTRUMENT PANEL

•Exhaust System Service Required - See Dealer —
This messages indicates regeneration has been disabled
due to a system malfunction. At this point the engine
Powertrain Control Module (PCM) will register a fault
code, the instrument panel will display a MIL light.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
• Exhaust Filter Full — Power Reduced See Dealer —
This message indicates the PCM has derated the
engine to limit the likelihood of permanent damage to
the after-treatment system. If this condition is not
corrected and a dealer service is not performed, exten-
sive exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have your
vehicle serviced by your local authorized dealer. NOTE:
Failing to follow the oil change indicator, chang-
ing your oil and resetting the oil change indicator by
0 miles remaining will prevent the diesel exhaust filter
from performing it’s cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized dealer will be
able to correct this condition.CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
