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 inter-
action on your part.
GETTING TO KNOW YOUR INSTRUMENT PANEL
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 sys-
tem. 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
instrument cluster display:

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
