GETTING TO KNOW YOUR INSTRUMENT PANEL 127
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 messages indicates regener-
ation 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).
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 oper-
ate your vehicle in areas where your exhaust sys-
tem can contact anything that can burn.
CAUTION!
The engine may be switched off even if the warn-
ing light is on: repeated interruptions of the
regeneration process could cause an early dete-
rioration 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 instructions
above. 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.
