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 Control Module (PCM). The PCM
manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input
or interaction on your part.
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
instrument cluster:
Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy — This message
will be displayed in the instrument cluster if
the exhaust particulate filter reaches 80% of
its maximum storage capacity. Under condi-
tions 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 instrument
cluster display. 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
Exhaust Filter XX% Full — This message indi-
cates 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

will hear one chime to assist in alerting you of
this condition.
Exhaust Service Required — See Dealer Now

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.
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
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such mate-
rials 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.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with contin-
ued operation.
