EXHAUST REGENERATION
This engine meets all required EPA 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). Additionally, 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 in the instrument cluster.
Diesel Particulate Filter (DPF) Messages
• “DPF cleaning: safely keep the vehicle moving” message on the instrument
cluster d Engine emission filter lamp lighted solid indicates that the
exhaust particulate filter loading is above the specified range and a regeneration
is required.
• Safely Drive at Highway Speeds to Remedy (the procedure lasts roughly 15 min-
utes at speed of about 40 mph (60 km/h) and with engine speed above
approximately 2000 rpm).
• When the exhaust filter is overloaded, the MIL lamp will turn on and the “Service
engine” message will display in the instrument cluster display, ETC lamp blinks
and the PCM limits the engine power to limit the likelihood of permanent damage
to the after-treatment system. To correct this condition, it will be necessary to have
your vehicle serviced by an authorized dealer.
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur soon
with continued operation.
