GETTING TO KNOW YOUR INSTRUMENT PANEL
Control Module (PCM). The PCM manages engine com-
bustion 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 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, occu-
pants 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.
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 Consis-
tent Speeds to Clear — This message will be dis-
played 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 con-
dition. 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 sys-
tem 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 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 dis-
play a Malfunction Indicator Light (MIL).
CAUTION!
See an 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,
extensive 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 Indi-
cator Light (MIL) and reduced engine power. Only an
authorized dealer will be able to correct this
condition.
CAUTION!
See an authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
FUEL SYSTEM MESSAGES
The following chart contains a list of different messages
that may appear in the instrument cluster, depending
on different system or fuel conditions. Use the descrip-
tions to interpret what the message means and deter-
mine the best action to take.
