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 XX% Full Safely Drive at Highway
Speeds to Remedy
— 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
