•Coolant Low— This telltale will turn on to indicate
the vehicle coolant level is low. See “Adding Coolant”
under the section “Maintaining Your Vehicle” for more
information.
Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced. 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.
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
Electronic Vehicle Information Center (EVIC):
•Perform Service— Your vehicle will require emissions
maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle
178 UNDERSTANDING YOUR INSTRUMENT PANEL

•Exhaust Service Required — See Dealer Now— 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 display a MIL light.
CAUTION!
See your 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, exten-
sive exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have your
vehicle serviced by your local authorized dealer.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Diesel Exhaust Fluid (DEF) Warning Messages
Your vehicle will begin displaying warning messages
when the DEF level reaches a driving range of approxi-
mately 350 miles (563 km). If the following warning
message sequence is ignored, your vehicle may be lim-
ited to a maximum speed of 5 MPH (8 km/H) unless DEF
is added.
•DEF Low Refill Soon— This message will display
when the low level is reached, during vehicle start up,

has increased.
•Add a minimum of 2 gallons (9.5 Liters) of DEF to the
tank in order to avoid vehicle operation at a maximum
speed of 5 MPH (8 km/H).
NOTE:A minimum of 2 gallons (9.5 Liters) may be
required to restore normal vehicle operation. Although
the vehicle will start normally and can be placed in gear
after this message has been initially displayed, extreme
caution should be utilized since the vehicle will only be
capable of maneuvering at a maximum speed of 5 MPH
(8 km/H).
