(RPM x 1000).
2. Electronic Vehicle Information Center (EVIC) Display •When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center
(EVIC) messages. Refer to “Electronic Vehicle Infor-
mation Center” in “Understanding Your Instrument

3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel filler door is located. 5. DEF Gauge
•The DEF Gauge displays the actual level of Diesel
Exhaust Fluid in the DEF tank. Diesel Exhaust Fluid
(DEF) is required to maintain normal vehicle opera-
tion and emissions compliance. If something is
wrong with the gauge, a DEF Warning Message or
Malfunction Indicator Light (MIL) will be displayed.
More information is available in the Electronic Ve-
hicle Information (EVIC) or Driver Information Dis-
play (DID) section under the heading of Diesel
Exhaust Fluid (DEF) Warning Messages.
NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.

the vehicle to a stop, and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads

remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.

Diesel Indicator Lights
Water In Fuel Indicator LightThe “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the fuel
filters. If this light remains on, DO NOT start
the vehicle before you drain the water from the
fuel filters to prevent engine damage. Refer to “Mainte-
nance Procedures/Draining Fuel/Water Separator Fil-
ters” in “Maintaining Your Vehicle” for further informa-
tion.
Wait To Start Light
The “Wait To Start Light” will illuminate when the
ignition is turned to the RUN position and the
intake manifold temperature is below 66°F (19°C). Wait
until the “Wait To Start Light” turns OFF, then start the
vehicle. Refer to “Starting Procedures” in “Starting and
Operating” for further information. NOTE:
The “Wait To Start Light” may not illuminate if
the intake manifold temperature is warm enough.
Low Coolant Level Indicator
This telltale will turn on to indicate the vehicle
coolant level is low.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate (engine
power reduction) is activated to protect the turbocharger
during engine start up in cold ambient temperatures.
•Engine Power Reduced During Warmup — This
message will display during start up when the ambi-
ent temperature is between 10° F (-12° C) and -10° F
(-23° C).

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 stan-
dards, 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 Pow-
ertrain Control Module (PCM). The PCM manages en-
gine 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
EVIC or DID:
•Perform Service — Your vehicle will require emissions
maintenance at a set interval. To help remind you
when this maintenance is due, the Cluster will display
“Perform Service”. When the “Perform Service” mes-
sage is displayed on the EVIC/DID it is necessary to
have the emissions maintenance performed. Emissions
maintenance may include replacing the Closed Crank-
case Ventilation (CCV) filter element. The procedure
for clearing and resetting the Perform Serviceindica-
tor message is located in the appropriate Service
Information.
• Exhaust System — Regeneration Required Now —
Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy will be displayed in the Cluster if the exhaust particulate filter reaches 80% of its maxi-
mum storage capacity. Under conditions of exclusive
short duration and low speed driving cycles, your
Cummins diesel engine and exhaust after-treatment
system may never reach the conditions required 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 EVIC/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
as little as 45 minutes, you can remedy the condition in
the particulate filter system and allow your Cummins
diesel engine and exhaust after-treatment system to
remove the trapped PM and restore the system to
normal operating condition.
