A MESSAGE FROM CHRYSLER GROUP LLC
Chrysler Group LLC and Cummins® welcome you as a
Cummins® turbocharged diesel-powered truck owner.
Your diesel truck will sound, feel, drive, and operate
differently from a gasoline-powered truck. It is important
that you read and understand this manual.
Almost 100% of the heavy duty trucks in the United
States and Canada are diesel-powered because of the fuel
economy, rugged durability, and high torque which permits pulling heavy loads. Cummins® engines power well
over half of these trucks. Now this same technology and
proven performance is yours in your truck equipped
with the Cummins® turbocharged diesel engine.
You may find that some of the starting, operating, and
maintenance procedures are different. However, they are
simple to follow and careful adherence to them will
ensure that you take full advantage of the features of this
engine.
NOTE: Some aftermarket products may cause severe
engine/transmission and/or exhaust system damage.
Your vehicle’s Powertrain Control Systems can detect
and store information about vehicle modifications that
increase horsepower and torque output such as whether
or not performance-enhancing powertrain components,
commonly referred to as downloaders, power boxes, or
performance chips have been used.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed. This
information can be retrieved by Chrysler Group LLC, and
service and repair facilities, when servicing your vehicle.
This information may be used to determine if repair will be
covered by the New Vehicle Limited Warranty.
There is a probability that the use of a “performance chip”
will prohibit the engine from starting. In this instance, the
vehicle will need to be serviced by a authorized dealer in
order to return the vehicle to it’s factory settings.

10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins® turbocharged diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
Do not operate the engine at idle for prolonged periods.
•
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
NOTE: Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting and Operating” of the
Owners Manual.
Because of the construction of the Cummins® turbocharged diesel engine, engine run-in is enhanced by
loaded operating conditions which allow the engine
parts to achieve final finish and fit during the first
6,000 miles (10 000 km).

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The tachometer indicates engine speed in Revolutions
Per Minute (RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
operation over 3200 RPM (Redline) can result in
significant damage that will not be covered under
warranty.
2. Anti-Lock Brake (ABS) Light
This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
UNDERSTANDING YOUR INSTRUMENT PANEL 13
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
3. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic (OBDII) system which
monitors the emissions and engine control system. If the vehicle is ready for emissions testing, the light
will come on when the ignition is first turned on and
remain on, as a bulb check, until the engine is started.
3
14 UNDERSTANDING YOUR INSTRUMENT PANEL
If the vehicle is not ready for emissions testing the light
will come on when the ignition is first turned on and
remain on for 15 seconds, then blink for 5 seconds, and
remain on until the vehicle is started. If the bulb does not
come on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
(Continued)
CAUTION! (Continued)
control system. It also could affect fuel economy and
drivability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
4. Turn Signal Indicators
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at a
rapid rate.
5. Engine Coolant Temperature
This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures when
driving in hot weather, up mountain grades, or in heavy
stop and go traffic. If the red Warning Light turns on
while driving, safely bring the vehicle to a stop, and turn
off the engine. DO NOT operate the vehicle until the
cause is corrected.
UNDERSTANDING YOUR INSTRUMENT PANEL 15
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
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.
6. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE: The light may flash momentarily during sharp
cornering maneuvers, which change fluid level conditions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the ABS, are also equipped with
Electronic Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn on
along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for approximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
UNDERSTANDING YOUR INSTRUMENT PANEL 17
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE: This light shows only that the parking brake is
applied. It does not show the degree of brake application.
7. High Beam Indicator
This indicator shows that headlights are on high
beam. Push the multifunction lever forward to
switch the headlights to high beam, and pull toward
yourself (normal position) to return to low beam.
8. Seat Belt Reminder Light
When the ignition switch is first turned to ON/
RUN, this light will turn on for four to eight
seconds as a bulb check. During the bulb check, if
the driver’s seat belt is unbuckled, a chime will sound.
After the bulb check or when driving, if the driver’s seat
belt remains unbuckled, the seat belt reminder light will

18 UNDERSTANDING YOUR INSTRUMENT PANEL
flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
9. Air Bag Warning Light
If the gauge pointer moves to either extreme of the gauge,
the Check Gauges indicator will illuminate and a single
chime will sound.
11. Speedometer
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not
on during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
10. Engine Oil Pressure
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/km/h).
12. Park/Headlight ON Indicator — If Equipped
This indicator will illuminate when the park
lights or headlights are turned on.
13. Cargo Light
The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
14. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON/RUN position.
15. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
16. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)
UNDERSTANDING YOUR INSTRUMENT PANEL 19
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
3
20 UNDERSTANDING YOUR INSTRUMENT PANEL
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
NOTE: The TPMS telltale is also accompanied by a “Low
Tire” message in the odometer (Base Cluster), or in the
Electronic Vehicle Information Center (EVIC) screen indicating “Low Tire” for EVIC enabled clusters.
17. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.

23. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously.
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
The “ESC Off Indicator Light” and the “ESC Activation/
Malfunction Indicator Light” come on momentarily each
time the ignition switch is turned to ON/RUN.
The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver that
caused the ESC activation.
24. DEF Gauge
