4 INTRODUCTION A MESSAGE FROM CHRYSLER GROUP LLC Chrysler Group LLC and Cummins威 welcome you as a Cummins威 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 per- mits pulling heavy loads. Cummins威 engines power well over half of these trucks. Now this same technology and proven performance is yours in your truck equipped with the Cummins威 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 New Vehicle Limited War- ranty.
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.

8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE STEERING WHEEL LOCK — IF EQUIPPED Your vehicle may be equipped with a passive steering wheel lock. This lock prevents steering the vehicle with- out the key fob. If the steering wheel is moved approxi- mately a half turn in either direction and the key fob is not in the ignition switch, the steering wheel will lock. To Manually Lock The Steering Wheel With the engine running, turn the steering wheel upside down, turn off the engine and remove the key fob. Turn the steering wheel slightly in either direction until the lock engages. To Release The Steering Wheel Lock Insert the key fob into the ignition switch and start the engine. If the key fob is difficult to turn, move the wheel slightly to the right or left to disengage the lock.
If you turned the wheel to the right to engage NOTE: the lock, you must turn the wheel slightly to the right to disengage it. If you turned the wheel to the left to engage the lock, turn the wheel slightly to the left to disengage it.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry (RKE) transmitter to start the engine conve- niently from outside the vehicle while still maintaining security. The system has a range of
approximately 328 ft (100 m). NOTE: • The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
• The remote start system will wait for the “Wait To Start Light” to extinguish before cranking the engine. This allows time for the intake heater to pre-heat the incoming air, and is normal operation in cold weather. Refer to “Electronic Vehicle Information Center/EVIC Warning Lights” in “Understanding Your Instrument Panel” for further information on and “Wait To Start Light” and 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 • BRAKE switch inactive (brake pedal not pressed)
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 9
• Ignition key removed from ignition switch • Battery at an acceptable charge level • RKE PANIC button not pressed • Fuel meets minimum requirement • Water In Fuel Indicator Light is not illuminated • Wait To Start Light is not illuminated

• Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
3. Fuel Gauge Shows level of fuel in tank when ignition switch is in the ON position. 4. Temperature Gauge The temperature gauge shows engine coolant tempera- ture. Any reading within the normal range indicates that the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher tempera- ture 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.
18 UNDERSTANDING YOUR INSTRUMENT PANEL
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- ship for service if your vehicle overheats.
5. Speedometer The speedometer shows the vehicle speed in miles per hour and/or kilometers per hour (MPH/km/h). 6. 4LOW Indicator Light – If Equipped
This light alerts the driver that the vehicle is in the four-wheel drive LOW mode. The front and rear driveshafts are mechanically locked to- gether forcing the front and rear wheels to rotate at the same speed. Low range provides a greater gear reduction ratio to provide increased torque at the wheels.
For vehicles equipped with a premium cluster this indi- cator will display in the Electronic Vehicle Information Center (EVIC). Refer to ”Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. 7. 4WD Indicator Light – If Equipped
This light indicates the vehicle is in four-wheel drive and 4LOCK. 4WD allows all four wheels to receive torque from the engine simultane- ously.
8. TOW/HAUL Indicator Light – If Equipped
The TOW HAUL button is located on the center stack switch bank. This light will illumi- nate when TOW HAUL mode is selected
the Electronic Stability Control
9. Electronic Stability Control (ESC) Indicator Light/Traction Control System (TCS) Indicator Light – If Equipped If (ESC)/ Traction Control System (TCS) Indicator Light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. This indicator light starts to flash as soon as the tires lose traction and the Electronic Stability Control (ESC) becomes active. The “ESC/TCS Indicator Light” also flashes when TCS is active. Be sure to adapt your speed and driving to the prevailing road conditions. If the “ESC/TCS Indicator Light” is on solid, the ESC system has been turned off by the driver or a temporary condition exists that will not allow full ESC function. 10. Exhaust Brake Indicator Light This light will illuminate when the exhaust brake has been turned on.

11. 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.
12. Oil Pressure Gauge 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. 13. Odometer/Trip Odometer Button Press this button to toggle between the odometer and the trip odometer display. Holding the button in resets the trip odometer reading when in trip mode.
20 UNDERSTANDING YOUR INSTRUMENT PANEL 14. Odometer/Electronic Vehicle Information Center (EVIC) Display
Odometer The odometer 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. Therefore, if the odometer reading is changed during repair or replacement, be sure to keep a record of the reading before and after the service so that the correct mileage can be determined. The two trip odometers show individual trip mileage. To switch from odometer to trip odometers, press and release the TRIP ODOMETER button. To reset a trip odometer, display the desired trip odom- eter to be reset then push and hold the button for approximately two seconds until the display resets.
15. Shift Lever Indicator This display indicator shows the transmission shift lever selection. 16. High Beam Indicator Light
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. 17. Voltmeter When the engine is running, the gauge indicates the electrical system voltage. The pointer should stay within the normal range if the battery is charged. If the pointer moves to either extreme left or right and remains there during normal driving, the electrical system should be serviced.
NOTE: The voltmeter may show a gauge fluctuation at various engine temperatures. This cycling operation is caused by the post-heat cycle of the intake manifold heater system. The number of cycles and the length of the cycling operation is controlled by the engine control module. Post-heat operation can run for several minutes, and then the electrical system and voltmeter needle will stabilize. 18. Cargo Light
The cargo light will illuminate when the cargo light is activated by pressing the cargo light button on the headlight switch.
19. 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
UNDERSTANDING YOUR INSTRUMENT PANEL 21
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). 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 capac- ity in the event of a failure to a portion of the hydraulic system. A leak in either half of the dual brake system is22 UNDERSTANDING YOUR INSTRUMENT PANEL 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 condi- tions. The vehicle should have service performed, and the brake fluid level checked. If brake failure is indicated, immediate repair is neces- sary.
WARNING!
Driving a vehicle with the “Brake Warning Light” on is dangerous. Part of the brake system may have failed. It will take longer to stop the vehicle. You could have an accident. 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 Warning 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 position. The light should illuminate for approxi- mately 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 position. NOTE: This light shows only that the parking brake is applied. It does not show the degree of brake application.
20. Anti-Lock Brake (ABS) Warning Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the ignition switch is turned to the ON position and may stay on for as long as four seconds.
If the “ABS Warning 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 Warning Light” is on, the brake system should be serviced as soon as possible to restore the benefits of anti-lock brakes. If the “ABS Warning Light” does not turn on when the ignition switch is turned to the ON position, have the light inspected by an authorized dealer.

21. Tire Pressure Monitoring Telltale Light – If Equipped
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 illumi- nates, 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
24 UNDERSTANDING YOUR INSTRUMENT PANEL 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. 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 subse- quent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the sys- tem 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 opera- tion or sensor damage may result when using re- placement 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 Electronic Vehicle Information Center (EVIC) screen. Refer to “Starting and Operating/ Tire Pressure Monitor System (TPMS)” in the Owner’s Manual for further information.
UNDERSTANDING YOUR INSTRUMENT PANEL 25
22. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic (OBDII) system which monitors the emissions and engine control sys- tem. 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. 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.
26 UNDERSTANDING YOUR INSTRUMENT PANEL 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 MIL on could cause damage to the engine control system. It also could affect fuel economy and drivability.
23. Airbag Warning Light
This light turns on and remains on for six to eight seconds as a bulb check when the ignition switch is first turned ON. If the light is not on during starting, stays on, or turns on while driving, have the system inspected by an authorized dealer as soon as possible.
24. Front Fog Light Indicator Light – If Equipped
This indicator will illuminate when the front fog lights are on.
25. Seat Belt Reminder Light
When the ignition switch is first turned ON, this light will turn on for five 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 flash or remain on continuously. Refer to ⬙Occupant Restraints/ Enhanced Seat Belt Use Reminder System (BeltAlert威)⬙ in “Things To Know Before Starting Your Vehicle” in the Owners Manual for further information.
26. Electronic Stability Control (ESC) OFF Indicator Light — If Equipped

The starter should not be operated for more than 15- second intervals. Waiting a few minutes between such intervals will protect the starter from overheating.
WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death. • Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal or the shift lever. Do not leave the key in the ignition. A child could operate power win- dows, other controls, or move the vehicle.
Manual Transmission – If Equipped Apply the parking brake, place the shift lever in NEU- TRAL and press the clutch pedal to the floor before starting the vehicle. This vehicle is equipped with a clutch interlocking ignition system. It will not start unless the clutch is fully pressed. Automatic Transmission – If Equipped Start the engine with the shift lever in NEUTRAL or PARK position. Apply the brake before shifting to any driving range. Tip Start Feature Do not press the accelerator. Turn the ignition switch briefly to the START position and release it. The starter motor will continue to run but will automatically disen- gage when the engine is running.
Extreme Cold Weather The Cummins威 diesel engine is equipped with several features designed to assist cold weather starting and operation: • The engine block heater is a resistance heater installed in the water jacket of the engine just above and behind the oil filter. It requires a 110–115 Volt AC electrical outlet with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized MOPAR威 dealer. • A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It is controlled by a built-in thermostat.
STARTING AND OPERATING 37
• A heated intake air system both improves engine starting and reduces the amount of white smoke generated by a warming engine.
Normal Starting Procedure – Engine Manifold Air Temperature Above 66°F (19°C) Observe the instrument panel cluster lights when starting the engine. 1. Always apply the parking brake. 2. Shift into PARK for an automatic transmission. For vehicles equipped with a manual transmission, fully press and hold the clutch pedal and shift into NEUTRAL. 3. Turn the ignition switch to the ON position and watch the instrument panel cluster lights.
38 STARTING AND OPERATING
CAUTION!
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO NOT START the engine before you drain the water from the fuel filter to avoid engine damage. Refer to “Maintenance Procedures/Draining Fuel/Water Sepa- rator Filter” in “Maintaining Your Vehicle” for fur- ther information.
4. Turn the ignition switch to the START position and crank the engine. Do not press the accelerator during starting.
Do not crank engine for more than 15 seconds at a time or starter motor damage may result. Turn the ignition switch to the OFF position and wait at least two minutes for the starter to cool before repeating start procedure.
5. When the engine starts, release the key fob. 6. Check to see that there is oil pressure. 7. Release the parking brake. Starting Procedure – Engine Manifold Air Temperature 0°F To 66°F (–18°C to 19°C)
NOTE: The temperature displayed in the Electronic Vehicle Information Center (EVIC) does not necessarily reflect the engine manifold air temperature. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un- derstanding Your Instrument Panel” for further informa- tion. When engine temperatures fall below 66°F (19°C) the “Wait To Start Light” will remain on indicating the intake manifold heater system is active. Follow the steps in the “Normal Starting” procedure except: 1. The “Wait To Start Light” will remain on for a period of time (length of time depends on engine temperature).
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO NOT START engine before you drain the water from the fuel filter to avoid engine damage. Refer to “Maintenance Procedures/Draining Fuel/Water Sepa- rator Filter” in “Maintaining Your Vehicle” for fur- ther information.
STARTING AND OPERATING 39
2. After the “Wait To Start Light” goes off, turn the ignition switch to the START position. Do not press the accelerator during starting.CAUTION!
Do not crank engine for more than 15 seconds at a time or starter motor damage may result. Turn the ignition switch to the OFF position and wait at least two minutes for the starter to cool before repeating start procedure.
3. After engine start-up, check to see that there is oil pressure. 4. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle. 5. Release the parking brake and drive.
40 STARTING AND OPERATING NOTE: • Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger at low coolant temperatures to improve engine warm- up. • If the engine stalls, or if the ignition switch is left ON for more than two minutes after the “Wait To Start Light” goes out, reset the grid heaters by turning the ignition switch to the OFF position for at least five seconds and then back ON. Repeat steps 1 through 5 of “Starting Procedure – Engine Manifold Air Tempera- ture Below 66°F (19°C).”Starting Procedure – Engine Manifold Air Temperature Below 0°F (-18°C) In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the manifold heaters twice before attempting to start the engine. This can be accomplished by turning the ignition OFF for at least five seconds and
then back ON after the “Wait To Start Light” has turned off, but before the engine is started. However, excessive cycling of the manifold heaters will result in damage to the heater elements or reduced battery voltage. NOTE: If multiple pre-heat cycles are used before starting, additional engine run time may be required to maintain battery state of charge at a satisfactory level. 1. If the engine stalls after the initial start, the ignition must be turned to the OFF position for at least five seconds and then to the ON position to recycle the manifold heaters. NOTE: Excessive white smoke and poor engine perfor- mance will result if manifold heaters are not recycled. 2. Heat generated by the manifold heaters dissipates rapidly in a cold engine. If more than two minutes pass between the time the “Wait To Start Light” turns off and
the engine is started, recycle the manifold heaters by turning the ignition switch to the OFF position for at least five seconds and then back ON. 3. If the vehicle is driven and vehicle speed exceeds 19 mph (31 km/h) before the manifold heater post-heat (after start) cycle is complete, the manifold heaters will shut off. 4. If the engine is started before the “Wait To Start Light” turns off, the preheat cycle will turn off. 5. If the engine is cranked for more than 10 seconds, the post-heat cycle will turn off. NOTE: • Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger at low coolant temperatures to improve engine warm- up.STARTING AND OPERATING 41
• When a diesel engine is allowed to run out of fuel or the fuel gels at low temperatures, air is pulled into the fuel system. If your engine has run out of fuel, refer to “Maintenance Procedures/Priming If The Engine Has Run Out Of Fuel” in “Maintaining Your Vehicle” for further information.
Starting Fluids
WARNING!
Starting fluids or flammable liquids are never to be used in the Cummins威 diesel engine (see Warning label). Never pour diesel fuel, flammable liquid, starting fluids (ether) into the air cleaner canister, air intake piping, or turbocharger inlet in an attempt to start the vehicle. This could result in a flash fire and explosion causing serious personal injury and engine damage.
42 STARTING AND OPERATING The engine is equipped with an automatic electric air preheating system. If the instructions in this manual are followed, the engine should start in all conditions.
WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death. • Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal or the shift lever. Do not leave the key in the ignition. A child could operate power win- dows, other controls, or move the vehicle.
NORMAL OPERATION – DIESEL ENGINE Observe the following when the engine is operating. • All message center lights are off. • Malfunction Indicator Light (MIL) is off. • Engine oil pressure is above 10 psi (69 kPa) at idle. • Voltmeter operation: • The voltmeter may show a gauge fluctuation at various engine temperatures. This cycling operation is caused by the post-heat cycle of the intake mani- fold heater system. The number of cycles and the length of the cycling operation is controlled by the engine control module. Post-heat operation can run for several minutes, and then the electrical system and voltmeter needle will stabilize.
• The cycling action will cause temporary dimming of the headlamps, interior lamps, and also a noticeable reduction in blower motor speed.
Cold Weather Precautions Operation in ambient temperature below 32°F (0°C) may require special considerations. The following charts sug- gest these options: Fuel Operating Range NOTE: Use “Ultra Low Sulfur Diesel Fuels” ONLY.
STARTING AND OPERATING 43
*No. 1 Ultra Low Sulfur Diesel Fuel should only be used where extended arctic conditions (-10°F/-23°C) exist. NOTE: • Use of Climatized Ultra Low Sulfur Diesel Fuel or Number 1 Ultra Low Sulfur Diesel Fuel results in a noticeable decrease in fuel economy. • Climatized Ultra Low Sulfur Diesel Fuel is a blend of Number 2 Ultra Low Sulfur and Number 1 Ultra Low Sulfur Diesel Fuels which reduces the temperature at which wax crystals form in fuel. • The engine requires the use of “Ultra Low Sulfur Diesel Fuel”. Use of incorrect fuel could result in engine and exhaust system damage. Refer to “Fuel Requirements” in “Starting and Operating” for further information.44 STARTING AND OPERATING Engine Oil Usage Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for the correct engine oil viscosity. Winter Front Usage If a winter front or cold weather cover is to be used, a percentage of the total grille opening area must be left uncovered to provide sufficient air flow to the charge air cooler and automatic transmission oil cooler. The per- centage of opening must be increased with the increasing ambient air temperature and/or engine load. If the cooling fan can be heard cycling frequently, increase the size of the opening in the winter front. A suitable cold weather cover is available from your MOPAR威 dealer. Battery Blanket Usage A battery loses 60% of its cranking power as the battery temperature decreases to 0°F (-18°C). For the same de- crease in temperature, the engine requires twice as much power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting capability at low temperatures. Suitable battery blankets are available from your authorized MOPAR威 dealer. Engine Warm-Up Avoid full throttle operation when the engine is cold. When starting a cold engine, bring the engine up to operating speed slowly to allow the oil pressure to stabilize as the engine warms up. NOTE: High-speed, no-load running of a cold engine can result in excessive white smoke and poor engine performance. No-load engine speeds should be kept under 1,200 RPM during the warm-up period, especially in cold ambient temperature conditions. Your vehicle is equipped with a turbo speed limiter, this feature limits the engine speed to 1,200 RPM when engine coolant temperatures are below 70°F (21°C). This feature is designed to protect the turbocharger from damage and will only operate in PARK or NEUTRAL.
If temperatures are below 32°F (0°C), operate the engine at moderate speeds for five minutes before full loads are applied. NOTE: • If ambient
temperatures are low and the coolant temperature is below 180°F (82°C), the engine idle speed will slowly increase to 1,000 RPM after two minutes of idle, if the following conditions are met: • foot is off brake pedal and throttle pedal • automatic transmission is in PARK • vehicle speed is zero • Applying the throttle will cancel fast idle • If the engine is equipped with an exhaust brake, operating the exhaust brake at idle will greatly im- prove warm up rate and will help keep the engine close to operating temperature during extended idle.
STARTING AND OPERATING 45
Engine Idling Avoid prolonged idling, long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely. Incomplete combustion allows carbon and varnish to form on piston rings, engine valves, and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine. If the engine is allowed to idle, under some conditions the idle speed may increase to 900 RPM then return to normal idle speed. This is normal operation. For EVIC messages related to the vehicle’s NOTE: exhaust system, refer to “Maintenance Procedures/ Intervention Regeneration Strategy – EVIC Message Pro- cess Flow” in “Maintaining Your Vehicle” for further information.
46 STARTING AND OPERATING Idle-Up Feature – Automatic Transmission Only The driver-controlled high idle speed feature will help increase cylinder temperatures and provide additional cab heat, however, excessive idling may still cause the exhaust aftertreatment system to not properly regenerate. Extended periods of idle time should be avoided. The Idle-Up feature uses the speed control switches to increase engine idle speed and quickly warm the vehi- cle’s interior. 1. With the transmission in PARK, the parking brake applied, and the engine running, press the speed control switch to the ON position, then press the SET switch. 2. The engine RPM will go up to 1100 RPM. To increase the RPM, press and hold the ACCEL/RESUME switch and the idle speed will increase to approximately 1500
RPM. To decrease the RPM, press and hold the DECEL switch and the idle speed will decrease to approximately 1100 RPM. 3. To cancel the Idle–Up feature, either press the CAN- CEL switch, press the ON/OFF switch, or press the brake pedal. Stopping The Engine Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine three to five minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the combustion chamber, bearings, internal components, and turbocharger. This is especially impor- tant for turbocharged, charge air-cooled engines.
it
transmissions,
NOTE: • During engine shut down on vehicles equipped with manual is normal for the diesel engine to resonate heavily for a moment during engine shut off. When the engine is connected to a manual transmission, this resonance causes load gear rattle from the transmission. This is commonly referred to as “shut down rattle.” The manufacturer recommends performing engine shut down with the clutch pedal pushed to the floor (clutch disengaged). When engine shut down is performed in this manner the rattle is reduced (not eliminated).

CAUTION!
Prevent overspeeding the engine going downhill. When descending steep grades, use a combination of gears and service brakes to control vehicle/engine speed. Overspeed can cause severe engine damage.
Snow Plow Mode Snow Plow Mode can be activated when the vehicle has a snow plow installed. This mode fully engages the fan clutch to increase the airflow when the plow is attached to the vehicle. NOTE: There may be an increase in fan noise and a decrease in fuel economy may result when using this feature. The fan clutch operation can be initiated by performing the following button sequence.
1. Turn the ignition key to the on position or start the vehicle. 2. Pull in the Cruise Control “Cancel” button/lever and hold. While holding the Cruise Control “Cancel”, push the “Exhaust Brake” button twice within five seconds. Repeat this sequence four times. The chime will sound twice as an audible indicator that the function is engaged. 3. To disable the function, repeat Step 2. The chime will sound four times as an audible indicator that the function is disengaged. Operating Precautions
Avoid Overheating The Engine The temperature of the engine coolant (antifreeze) (a mixture of 50% ethylene-glycol and 50% water) must not exceed the normal range of the temperature gauge 240°F (116°C) with a 16 psi (110 kPa) radiator cap.
Usually the engine coolant (antifreeze) temperature indi- cated during operation will be to the left of center in the normal range of the gauge. Avoid Low Coolant Temperature Operation Continual operation at low engine coolant (antifreeze) temperature below the normal range on the gauge 140°F (60°C) can be harmful to the engine. Low engine coolant (antifreeze) temperature can cause incomplete combus- tion which allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the lubricating oil and causing rapid wear to the engine. Cooling System Tips – Automatic Transmission To reduce potential for engine and transmission over- heating in high ambient temperature conditions, take the following actions:
STARTING AND OPERATING 49
• City Driving — When stopped, shift the transmission into NEUTRAL and increase engine idle speed. • Highway Driving — Reduce your speed. • Up Steep Hills — Select a lower transmission gear, but try and keep the torque converter clutch engaged. • Air Conditioning — Turn it off temporarily. Do Not Operate The Engine With Low Oil Pressure When the engine is at normal operating temperature, the minimum oil pressures required are:
Idle 700 to 800 RPM . . . . . . . . . . . . . . . 10 psi (69 kPa) Full speed and load . . . . . . . . . . . . . . 30 psi (207 kPa)
50 STARTING AND OPERATING
CAUTION!
If oil pressure falls to less than normal readings, shut the engine off immediately. Failure to do so could result in immediate and severe engine damage.
Do Not Operate The Engine With Failed Parts Practically all failures give some warning before the parts fail. Be on the alert for changes in performance, sounds, and visual evidence that the engine requires service. Some important clues are: • engine misfiring or vibrating severely • sudden loss of power • unusual engine noises • fuel, oil or coolant leaks • sudden change, outside the normal operating range, in
the engine operating temperature
• excessive smoke • oil pressure drop ENGINE BLOCK HEATER — IF EQUIPPED The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the heater cord to a ground-fault interrupter protected 110–115 Volt AC electrical outlet with a grounded, three-wire exten- sion cord. The engine block heater cord is routed under the hood to the right side and can be located just behind the grille near the headlamp. NOTE: The engine block heater cord is a factory in- stalled option. If your vehicle is not equipped, heater cords are available from your authorized MOPAR威 dealer. The block heater must be plugged in at least one hour to have an adequate warming effect on the coolant.
WARNING!
Remember to disconnect the cord before driving. Damage to the 110–115 Volt electrical cord could cause electrocution.
NOTE: The block heater will require 110 Volts AC and 6.5 Amps to activate the heater element. Block Heater Usage For ambient temperatures below 0°F (-18°C), engine block heater usage is recommended. For ambient temperatures below –20°F (-29°C), engine block heater usage is required.
DIESEL EXHAUST BRAKE (ENGINE BRAKING) — IF EQUIPPED The exhaust brake feature will only function when the driver turns the exhaust brake switch to the ON position.
STARTING AND OPERATING 51
Exhaust Brake Switch
Once the switch is in the ON position and the vehicle is moving faster than 5 mph (8 km/h); the exhaust brake will automatically operate when the driver removes pressure from the accelerator pedal. Exhaust braking is most effective when the engine RPM is higher. The automatic transmission has been programmed in TOW/
52 STARTING AND OPERATING HAUL mode only to downshift more aggressively when the exhaust brake is enabled to increase brake perfor- mance.
CAUTION!
Use of aftermarket exhaust brakes is not recom- mended and could lead to engine damage
WARNING!
Do not use the exhaust brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause an accident possi- bly resulting in personal injury or death.
NOTE: For optimum braking power it is recommended to use the exhaust brake while in TOW/HAUL mode. The purpose of the exhaust brake (engine braking) fea- ture is to supply negative (braking) torque to the engine. Typically, the engine braking is used for, but not limited to, vehicle towing applications where vehicle braking can be achieved by the internal engine power, thereby spar- ing the mechanical brakes of the vehicle. Benefits of the exhaust brake are: • vehicle driving control • reduced brake fade • longer brake life • faster cab warm-up.
STARTING AND OPERATING 53
CAUTION! (Continued)
• Shift into or out of REVERSE only after the vehicle has come to a complete stop and the engine is at idle speed. • Do not shift between PARK, REVERSE, NEU- TRAL, or DRIVE into any forward gear when the engine is above idle speed. • Before shifting into any gear, make sure your foot
is firmly pressing on the brake pedal.
The exhaust brake feature can also be used to reduce the engine warm up time. To use the exhaust brake as a warm-up device, the vehicle must be stopped or moving less than 5 mph (8 km/h), the exhaust brake switch must be in the ON position, and the coolant temperature must be below 180°F (82°C) and ambient temperature below 60°F (16°C).
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow- ing precautions are not observed: • Shift into PARK only after the vehicle has come to
a complete stop.
(Continued)
54 STARTING AND OPERATING
WARNING!
• Unintended movement of a vehicle could injure those in and near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, apply the park- ing brake, shift the transmission into PARK, and remove the key fob. Once the key fob is removed, the shift lever is locked in the PARK position, securing the vehicle against unwanted movement. Furthermore, you should never leave unattended children inside a vehicle.
(Continued)
WARNING! (Continued)
• Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal or the shift lever. Do not leave the key fob in the vehicle. A child could operate power windows, other controls, or move the vehicle. • It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly pressing on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or some- thing. Only shift into gear when the engine is idling normally and when your right foot is firmly pressing on the brake pedal.
Key Ignition Park Interlock This vehicle is equipped with a Key Ignition Park Inter- lock which requires the shift lever to be placed in PARK before the ignition switch can be turned to the LOCK/ OFF position. The key fob can only be removed from the ignition when the ignition is in the LOCK/OFF position and once removed the shift lever is locked in PARK. Brake/Transmission Shift Interlock System This vehicle is equipped with a Brake Transmission Shift Interlock System (BTSI) that holds the shift lever in the PARK position when the ignition switch is in the LOCK/ OFF position. To move the shift lever out of the PARK position, the ignition switch must be turned to the ON/RUN position (engine running or not) and the brake pedal must be pressed.
STARTING AND OPERATING 55
Six-Speed Automatic Transmission – If Equipped (Ram Truck Only) The shift lever position display (located in the instrument panel cluster) indicates the transmission gear range. The shift lever is mounted on the right side of the steering column. You must press the brake pedal to move the shift lever out of the PARK position (refer to “Brake/ Transmission Shift Interlock System” in this section). To drive, move the shift lever from PARK or NEUTRAL to the DRIVE position. Pull the shift lever toward you when shifting into REVERSE or PARK, or when shifting out of PARK. The electronically-controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new vehicle may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles (kilometers).56 STARTING AND OPERATING Shifting from DRIVE to PARK or REVERSE should be done only after the accelerator pedal is released and the vehicle is stopped. Be sure to keep your foot on the brake pedal when moving the shift lever between these gears. The transmission shift lever has only Park, Reverse, Neutral, and Drive shift positions. Manual downshifts can be made using the Electronic Range Select (ERS) shift control (described later). Pressing the ERS (-/+) buttons while in the DRIVE position will select the highest available transmission gear, and will display that gear in the instrument cluster as 6, 5, 4, 3, 2, 1. Gear Ranges DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range.
PARK This range supplements the parking brake by locking the transmission. The engine can be started in this range. Never attempt to use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. When parking on a level surface, you may place the shift lever in the PARK position first, and then apply the parking brake. When parking on a hill, apply the parking brake before placing the shift lever in PARK, otherwise the load on the transmission locking mechanism may make it difficult to move the shift lever out of PARK. As an added precau- tion, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade.
STARTING AND OPERATING 57
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle movement and possible injury or damage. • Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the shift lever clockwise without first pull- ing it toward you after you have placed it in PARK. Make sure the transmission is in PARK before leaving the vehicle.
WARNING! (Continued)
• It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly pressing on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or some- thing. Only shift into gear when the engine is idling normally and when your foot is firmly pressing on the brake pedal.

WARNING! (Continued)
• Unintended movement of a vehicle could injure those in and near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, always apply the parking brake, shift the transmission into PARK, and remove the key fob. Once the key fob is removed, the shift lever is locked in the PARK position, securing the vehicle against unwanted movement. Furthermore, you should never leave unattended children inside a vehicle. • Never leave children alone in a vehicle. Leaving unattended children in a vehicle is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Do not leave the key fob in the vehicle. A child could operate power windows, other controls, or move the vehicle.
CAUTION!
• Before moving the shift lever out of PARK, you must turn the ignition switch from the LOCK/OFF position to the ON/RUN position, and also press the brake pedal. Otherwise, damage to the shift lever could result. • DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage the drivetrain.
The following indicators should be used to ensure that you have engaged the shift lever into the PARK position: • When shifting into PARK, pull the shift lever toward you and move it all the way counterclockwise until it stops. • Release the shift lever and make sure it is fully seated
in the PARK gate.
• Look at the shift lever position display and verify that • With brake pedal released, verify that the shift lever
it indicates the PARK position.
will not move out of PARK.
REVERSE This range is for moving the vehicle backward. Shift into REVERSE only after the vehicle has come to a complete stop. NEUTRAL Use this range when the vehicle is standing for prolonged periods with the engine running. The engine may be started in this range. Set the parking brake and shift the transmission into PARK if you must leave the vehicle.
STARTING AND OPERATING 59
WARNING!
Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have an accident.
CAUTION!
Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can result in severe transmission damage. Refer to “Recre- ational Towing” in “Starting And Operating” and “Towing A Disabled Vehicle” in “What To Do In Emergencies” for further information.
60 STARTING AND OPERATING DRIVE This range should be used for most city and highway driving. It provides the smoothest upshifts and down- shifts, and the best fuel economy. The transmission automatically upshifts through underdrive first, second, and third gears, direct fourth gear and overdrive fifth and sixth gears. The DRIVE position provides optimum driv- ing characteristics under all normal operating conditions. When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading condi- tions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the Electronic Range Select (ERS) feature (refer to “Electronic Range Select (ERS)” in this section) to select a lower gear range. Under these conditions, using a lower gear range will improve performance and extend transmission life by reducing excessive shifting and heat buildup.
If the transmission operating temperature exceeds nor- mal operating limits, the powertrain controller will modify the transmission shift schedule and expand the range of torque converter clutch engagement. This is done to prevent transmission damage due to overheat- ing. If the transmission becomes extremely hot, the “Trans- mission Temperature Warning Light” may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. NOTE: Use caution when operating a heavily loaded vehicle at low speeds (such as towing a trailer up a steep grade, or in stop-and-go traffic) during hot weather. In these conditions, torque converter slip can impose a significant additional heat load on the cooling system. Downshifting the transmission to the lowest possible
gear (when climbing a grade), or shifting to NEUTRAL (when stopped in heavy traffic) can help to reduce this excess heat generation. During cold temperatures, transmission operation may be modified depending on engine and transmission temperature as well as vehicle speed. This feature im- proves warm up time of the engine and transmission to achieve maximum efficiency. Engagement of both the torque converter clutch and the top overdrive gear are inhibited until the transmission fluid is warm (refer to the “Note” under “Torque Converter Clutch” in this section). During extremely cold temperatures (-16°F [-27°C] or below), operation may briefly be limited to first and direct gears only. Normal operation will resume once the transmission temperature has risen to a suitable level. Transmission Limp Home Mode Transmission function is monitored electronically for abnormal conditions. If a condition is detected that could
STARTING AND OPERATING 61
result in transmission damage, Transmission Limp Home Mode is activated. In this mode, the transmission remains in fourth gear regardless of which forward gear is selected. PARK, REVERSE, and NEUTRAL will continue to operate. Limp Home Mode allows the vehicle to be driven to an authorized dealer for service without dam- aging the transmission. In the event of a momentary problem, the transmission can be reset to regain all forward gears by performing the following steps: 1. Stop the vehicle. 2. Shift the transmission into PARK. 3. Turn the ignition switch to the LOCK/OFF position. 4. Wait approximately 10 seconds. 5. Restart the engine.You can switch between DRIVE and ERS mode at any vehicle speed. When the shift lever is in the DRIVE position, the transmission will operate automatically, shifting between all available gears. Tapping the ERS (-) switch will activate ERS mode, display the current gear in the instrument cluster, and maintain that gear as the top available gear. Once in ERS mode, tapping the ERS (-) or (+) switch will change the top available gear.
62 STARTING AND OPERATING 6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal operation. NOTE: Even if the transmission can be reset, we recom- mend that you visit your authorized dealer at your earliest possible convenience. Your authorized dealer has diagnostic equipment to determine if the problem could recur. If the transmission cannot be reset, authorized dealer service is required. Electronic Range Select (ERS) Operation The Electronic Range Select (ERS) shift control allows the driver to limit the highest available gear when the shift lever is in the DRIVE position. For example, if you shift the transmission into 3 (third gear), the transmission will never shift above third gear, but will shift down into second and first gear normally.

WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid, causing an accident or personal injury.

64 STARTING AND OPERATING Overdrive Operation The automatic transmission includes an electronically controlled Overdrive (fifth and sixth gears). The trans- mission will automatically shift into the Overdrive gear if the following conditions are present: • the shift lever is in the DRIVE position, • the transmission fluid has reached an adequate tem- • the engine coolant has reached an adequate tempera- • vehicle speed is sufficiently high, and • the TOW/HAUL switch has not been activated. When To Use TOW/HAUL Mode When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the TOW/HAUL switch to select TOW/
ture,
HAUL mode. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, transmission upshifts are delayed, and the trans- mission will automatically downshift (for engine brak- ing) during steady braking maneuvers.
TOW/HAUL Switch
The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to indicate that TOW/HAUL mode has been activated. Pressing the switch a second time restores normal operation. If the TOW/HAUL mode is desired, the switch must be pressed each time the engine is started.
WARNING!
Do not use the “TOW/HAUL” feature when driving in icy or slippery conditions. The increased engine braking could cause the rear wheels to slide, and the vehicle to swing around with the possible loss of vehicle control, which could cause an accident possi- bly resulting in personal injury or death.
Torque Converter Clutch A feature designed to improve fuel economy has been included in the automatic transmission on your vehicle.
STARTING AND OPERATING 65
A clutch within the torque converter engages automati- cally at calibrated speeds. This may result in a slightly different feeling or response during normal operation in the upper gears. When the vehicle speed drops or during some accelerations, the clutch automatically disengages. NOTE: • The torque converter clutch will not engage, and the transmission will not shift to sixth gear, until the transmission fluid and engine coolant are warm [usu- ally after 1 to 3 miles (1.6 to 4.8 km) of driving]. Because sixth gear is disabled, and engine speed is higher when the torque converter clutch is not en- gaged, it may seem as if the transmission is not shifting properly when cold. This is normal. Using the Electronic Range Select (ERS) feature, when the trans- mission is sufficiently warm, will demonstrate that the transmission is able to shift into and out of Overdrive.66 STARTING AND OPERATING
• If the vehicle has not been driven for several days, the first few seconds of operation after shifting the trans- mission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not cause damage to the transmission. The torque con- verter will refill within five seconds after starting the engine.
Six-Speed Automatic Transmission – If Equipped (Chassis Cab Only) The shift lever position display (located in the instrument panel cluster) indicates the transmission gear range. The shift lever is mounted on the right side of the steering column. You must press the brake pedal to move the shift lever out of the PARK position (refer to “Brake/ Transmission Shift Interlock System” in this section). To drive, move the shift lever from PARK or NEUTRAL to
the DRIVE position. Pull the shift lever toward you when shifting into REVERSE or PARK, or when shifting out of PARK. The electronically-controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new vehicle may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles (kilometers). Shifting from DRIVE to PARK or REVERSE should be done only after the accelerator pedal is released and the vehicle is stopped. Be sure to keep your foot on the brake pedal when moving the shift lever between these gears. The transmission shift lever has only PARK, REVERSE, NEUTRAL, and DRIVE shift positions. Manual down- shifts can be made using the Electronic Range Select (ERS) shift control (described later). Pressing the ERS (-/+) switches (on the shift lever) while in the DRIVE
position will select the highest available transmission gear, and will display that gear in the instrument cluster as 6, 5, 4, 3, 2, 1. Gear Ranges DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range. PARK This range supplements the parking brake by locking the transmission.
