DIESEL MESSAGES AND WARNINGS
Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all diesel
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.
Your vehicle has the ability to alert you to
additional maintenance required on your vehicle or
engine. The following messages may display in
your instrument cluster display:
Perform Service
— Your vehicle will require emis -
sions maintenance at a set interval. To help
remind you when this maintenance is due, the
instrument cluster display will display “Perform
Service”. When the “Perform Service” message
is displayed in the instrument cluster display it is
necessary to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase Ventila -
tion (CCV) filter element. The procedure for
clearing and resetting the "Perform Service"
indicator message is located in the appropriate
Service Information.

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.

Engine Power Reduced Up To 2 Min (Minutes)
During Warm-up — This message will display
during start-up when the ambient temperature
is -25°F (-32°C) and below.
Your vehicle is equipped with an engine warm
up protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed
is limited is dependent upon engine coolant
temperature. Engine speed may be briefly
limited to 1,000 RPM after starting with coolant
temperature below freezing conditions, and
may be limited to 1,000 RPM for up to approxi -
mately two minutes under more severe cold
conditions.
Coolant Low — This telltale will turn on to indi -
cate the vehicle coolant level is low
Ú page 353.

the DEF system is not serviced within less than
200 miles (322 km) of the fault being detected. When the DEF system needs to be serviced the
following warnings will display:


DEF Low Refill Soon

— This message will display
when the low level is reached, during vehicle start
up, and with increased frequency during vehicle
operation. It will be accompanied by a single
chime. Approximately 5 gallons (19 Liters) of DEF
is required to refill the tank when this message is
initially displayed on pickup applications, and
approximately 7 gallons (26 Liters) are required
on chassis-cab applications.

Speed Limited to 5 MPH in XXX mi Refill DEF —
This message will continuously display if the
“DEF Low Refill Soon” message is ignored, and
the frequency of occurrence of the chime will
increase unless up to 2 gallons (7.5 Liters) of
DEF is added to the tank.
5 MPH Max Speed on Restart, Long Idle or
Refuel Refill DEF — This message will continu -
ously display when the counter reaches zero,
and will be accompanied by a periodic chime.
The vehicle will only be capable of a maximum
speed of 5 mph upon the first of the following
conditions to occur:
If the vehicle is shutoff and restarted.
If the vehicle is idled for an extended period
of time, approximately one hour or greater.
If the system detects that the level of fuel in
the tank has increased. Add a minimum of 2 gallons (7.5 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 (7.5 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).

BATTERY SAVER ON/BATTERY SAVER
M
ODE MESSAGE — ELECTRICAL LOAD
R
EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery
Sensor (IBS) to perform additional monitoring of
the electrical system and status of the vehicle
battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions will
take place to extend the driving time and distance
of the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a risk
of battery depletion to the point where the vehicle
may stall due to lack of electrical supply, or will not
restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
