120 GETTING TO KNOW YOUR INSTRUMENT PANEL
DIESEL PARTICULATE FILTER (DPF)
M
ESSAGES
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 display:
Exhaust Filter Nearing Full Safely Drive at Consistent
Speeds to Clear — This message will be displayed 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. 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 DPF is
self-cleaning. Maintain your current driving condition
until regeneration is completed.
Exhaust System — Regeneration Completed —
This message indicates that the DPF self-cleaning is
completed. If this message is displayed, you will hear
one chime to assist in alerting you of this condition.
Exhaust System Service Required — See Dealer —
This message 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 Malfunction Indicator Light (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 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 an authorized dealer.
NOTE:
Failing to follow the oil change indicator, changing your
oil and resetting the oil change indicator by 0 miles
(0 kilometers) remaining will prevent the diesel exhaust
filter from performing its cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and reduced
engine power. Only an authorized dealer will be able to
correct this condition.
WARNING!
A malfunctioning catalytic converter, as previously
referenced, can reach higher temperatures than in
normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as
dry plants, wood, cardboard, etc. This could result in
death or serious injury to the driver, occupants or
others.
CAUTION!
The engine may be switched off even if the warning
light is on: repeated interruptions of the regeneration
process could cause an early deterioration of engine oil.
For this reason it is always advisable to wait for the
symbol to go off before turning off the engine, following
the previously mentioned instructions. Do not complete
the DPF regeneration process when the vehicle is
stopped.
CAUTION!
See an authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
CAUTION!

system could occur soon with continued operation.
