A MESSAGE FROM CHRYSLER GROUP LLC

Chrysler Group LLC welcomes you as a turbocharged diesel-powered vehicle owner. Your diesel vehicle will sound, feel, drive and operate differently from a gasoline­powered vehicle. It is important that you read and understand this manual.
Almost 100% of the heavy 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.
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.
Any chassis/suspension or tire size modifications to the vehicle will effect the performance of the Adaptive Cruise Control and Forward Collision Warning Sys­tem.
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 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.

REMOTE STARTING SYSTEM

This system uses the Remote Keyless Entry (RKE) transmitter to start the engine conve­niently from outside the vehicle while still maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
The vehicle must be equipped with an automatic transmission to be equipped with Remote Start.
Obstructions between the vehicle and the RKE trans­mitter may reduce this range.
weather. Refer to “Electronic Vehicle Information Dis­play (EVIC)” in “Understanding Your Instrument Panel” for further information on the “Wait To Start” amber telltale and the pre-heat cycle.

How To Use Remote Start

All of the following conditions must be met before the engine will remote start:
Shift lever in PARK
Doors closed
Hood closed
HAZARD switch off
The Remote Start system will wait for the “Wait To
Start” amber telltale to extinguish before cranking the engine. This allows time for the engine pre-heat cycle to pre-heat the cylinder air, and is normal in cold
BRAKE switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
RKE PANIC button not pressed
Fuel meets minimum requirement
System not disabled from previous remote start event
Vehicle security alarm not active
Water In Fuel Indicator Light is not illuminated
“Wait To Start” telltale is not illuminated
WARNING!
Do not start or run an engine in a closed garage or confined area. Exhaust gas contains Carbon Mon­oxide (CO) which is odorless and colorless. Carbon Monoxide is poisonous and can cause serious in­jury or death when inhaled.
Keep Remote Keyless Entry (RKE) transmitters away from children. Operation of the Remote Start System, windows, door locks or other controls could cause serious injury or death.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 9

ENGINE BREAK-IN RECOMMENDATIONS

The 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.

10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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.
The engine oil installed in the engine at the factory is a high-quality energy conserving type lubricant. Oil changes should be consistent with anticipated climate conditions under which vehicle operations will occur. The recommended viscosity and quality grades are shown under “Fluids, Lubricants and Genuine Parts”, under “Maintaining Your Vehicle” in this manual. NON­DETERGENT OR STRAIGHT MINERAL OILS MUST NEVER BE USED.

INSTRUMENT CLUSTER DESCRIPTIONS

1. Tachometer
Indicates the engine speed in revolutions per minute (RPM x 1000).
2. Seat Belt Reminder Light
When the ignition switch is first turned to the ON/RUN position, 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 or front passenger seat belt remains unbuckled, the Seat Belt Indicator Light will flash or remain on continuously. Refer to “Occupant Restraints” in “Things To Know Before Starting Your Vehicle” for further information.
UNDERSTANDING YOUR INSTRUMENT PANEL 13
3. 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.
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.
4. High Beam Indicator
Indicates that headlights are on high beam.

5. Front Fog Light Indicator — If Equipped
8. Speedometer
This indicator will illuminate when the front fog
lights are on.
6. LH Selectable DID
This area of the cluster will display selectable informa­tion such as compass, outside temperature, etc. For further information, refer to “Driver Information Display (DID)” in this section.
7. Turn Signal Indicator
The arrows will flash with the exterior turn sig-
nals when the turn signal lever is operated. A tone will chime, and a DID message will appear if either turn signal is left on for more than 1 mile (1.6 km).
NOTE: If either indicator flashes at a rapid rate, check for a defective outside light bulb.
Indicates vehicle speed.
9. RH Selectable DID
This area of the cluster will display selectable informa­tion such as compass, outside temperature, etc. For further information, refer to “Driver Information Display (DID)” in this section.
10. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con­trol systems. The light will illuminate when the key is in the ON/RUN position before engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the condition checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start. The vehicle should be serviced if the light stays on through several of your typical driving cycles. In most situations, the vehicle will drive normally and will not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause damage to the engine control system. It also could affect fuel economy and driveability. If the MIL is flashing, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
UNDERSTANDING YOUR INSTRUMENT PANEL 15
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.
11. Electronic Park Brake Failure Indicator — If Equipped
This light indicates the Electronic Parking Brake system requires service.
3
16 UNDERSTANDING YOUR INSTRUMENT PANEL
12. Temperature Gauge
The temperature gauge shows engine coolant tempera­ture. Any reading within the normal range indicates that the engine cooling system is operating properly.
The gauge pointer will likely indicate a higher tempera­ture when driving in hot weather, up mountain grades, or when towing a trailer. It should not be allowed to exceed the upper limits of the normal operating range.
NOTE: Temperature readings in the orange range of the gauge are acceptable under some high load condition. If the gauge points to the H or #Engine Temperature Hot# DID message appears a light and a single chime will require driver correction.
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.
13. 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.
UNDERSTANDING YOUR INSTRUMENT PANEL 17
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.
3
18 UNDERSTANDING YOUR INSTRUMENT PANEL
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 Anti-Lock Brake System (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.
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.
14. Fuel Gauge/Fuel Door Reminder
The fuel pump symbol points to the side of the vehicle where the fuel door is located. The pointer shows the level of fuel in the fuel tank when the ignition switch is in the ON/RUN position.
15. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated 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.)
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
UNDERSTANDING YOUR INSTRUMENT PANEL 19
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.
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
3
20 UNDERSTANDING YOUR INSTRUMENT PANEL
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! (Continued)
sensor to become inoperable. After using an after­market tire sealant it is recommended that you take your vehicle to an authorized dealership to have your sensor function checked.
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. Using aftermarket tire sealants may cause the Tire Pressure Monitoring System (TPMS)
(Continued)
16. Driver Information Display (DID)
The odometer display shows the total distance the ve­hicle has been driven.
U.S. Federal regulations require that upon transfer of vehicle ownership, the seller certify to the purchaser the correct mileage that the vehicle has been driven. If your odometer needs to be repaired or serviced, the repair technician should leave the odometer reading the same as it was before the repair or service. If she/he cannot do so, then the odometer must be set at zero, and a sticker must be placed in the door jamb stating what the mileage was before the repair or service. It is a good idea for you
to make a record of the odometer reading before the repair/service, so that you can be sure that it is properly reset, or that the door jamb sticker is accurate if the odometer must be reset at zero.
When the appropriate conditions exist, this Driver Infor­mation Display (DID) messages. Refer to “Driver Infor­mation Display” of your owners manual for more information.
17. Selectable DID Menu
This area of the cluster will display the DID selectable menu. For further information, refer to “Driver Informa­tion Display (DID)” in this section.
18. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to the ON/RUN position. If the light is
either not on during starting, stays on, or turns
UNDERSTANDING YOUR INSTRUMENT PANEL 21
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” of your owners manual for further information.
19. Vehicle Security Light
This light will flash rapidly for approximately 15 seconds when the vehicle theft alarm is arming. The light will flash at a slower speed
continuously after the alarm is set. The security light will also come on for about three seconds when the ignition is first turned on.
20. Electronic Stability Control (ESC) OFF Indicator Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.

22 UNDERSTANDING YOUR INSTRUMENT PANEL
21. Electronic Stability Control (ESC) Activation/ Malfunction Indicator Light — If Equipped
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.
Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if it was turned off previously.
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.
22. Park/Headlight ON Indicator — If Equipped
This indicator will illuminate when the park lights or headlights are turned on.
