ENGINE BREAK-IN RECOMMENDATIONS
3.6L Engine Break-In
For vehicles equipped with the 3.6L, use the following engine break-in recommendations:
A long break-in period is not required for the drivetrain (engine, transmission, clutch,
and rear axle) in your new vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws
contributes to a good break-in. However, wide-open throttle acceleration in low gear
can be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant installed at the factory is
high-quality and energy-conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under which vehicle operations
will occur. For the recommended viscosity and quality grades, refer to “Maintenance
Procedures” in “Maintaining Your Vehicle”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during its first few thousand miles (kilometers)
of operation. This should be considered a normal part of the break-in and not
interpreted as an indication of difficulty. Please check your oil level with the engine
oil indicator often during the break in period. Add oil as required.
5.7L Engine Break-In
For vehicles equipped with the 5.7L, use the following engine break-in recommendations:
A long break-in period is not required for the drivetrain (engine, transmission, clutch,
and rear axle) in your new vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.

6.4L Engine Break-In
For vehicles equipped with the 6.4L use the following engine break-in recommendations:
Despite modern technology and World Class manufacturing methods, the moving
parts of the vehicle must still wear in with each other. This wearing in occurs mainly
during the first 500 miles (805 km) and continues through the first oil change
interval.
It is recommended for the operator to observe the following driving behaviors during
the new vehicle break-in period:
0 to 100 miles (0 to 160 km):
• Do not allow the engine to operate at idle for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
100 to 300 miles (160 to 483 km):
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.
• Drive with the engine speed less than 5,000 RPM.
• Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting manually (paddles or gear shift) at higher rpms when possible.
• Do not perform sustained operation with the accelerator pedal at wide open throttle.
• Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.
OPERATING YOUR VEHICLE

For the first 1500 miles (2414 km):
• Do not participate in track events, sport driving schools, or similar activities duringthe first 1500 miles (2414 km).
NOTE:
Check engine oil with every refueling and add if necessary. Oil and fuel consumption
may be higher through the first oil change interval.
HEADLIGHT SWITCH
The headlight switch is located on the left side of the instrument panel, next to the
steering wheel. The headlight switch controls the operation of the headlights, parking
lights, instrument panel lights, cargo lights and fog lights (if equipped).
To turn on the headlights, rotate the
headlight switch clockwise. When the
headlight switch is on, the parking lights,
taillights, license plate light and instru-
ment panel lights are also turned on. To
turn off the headlights, rotate the head-
light switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass
lights. Plastic is not as scratch resis-
tant as glass and therefore different
lens cleaning procedures must be fol-
lowed.
• To minimize the possibility of scratch- ing the lenses and reducing light out-
put, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild
soap solution followed by rinsing.
CAUTION!
Do not use abrasive cleaning components, solvents, steel wool or other abrasive
materials to clean the lenses.

DIESEL 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 carrying or towing significantweight.
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. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the gear selector is in the PARK position.
3. Press and hold the brake pedal while pushing the ENGINE START/STOP button once and the system will engage the starter to crank the engine.
NOTE: • A delay of the start of up to five seconds is possible under very cold conditions.The “Wait to Start” telltale will be illuminated during the pre-heat process,
When the engine Wait To Start light goes off the engine will automatically crank.
• If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
4. Check that the oil pressure warning light has turned off.
5. Release the parking brake.

– Transmission Temperature Warning Light
This light indicates that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle, with the transmission in NEUTRAL, until the light turns
off. Once the light turns off, you may continue to drive normally.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated
will eventually cause severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the Transmission Temperature Warning
Light is illuminated you could cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
– 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.
– 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 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” in your Owner’s Manual on the DVD for further
information.
NOTE:
The Air Bag System is designed to be maintenance free.
WHAT TO DO IN EMERGENCIES
190
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty
and off road environment or is operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder and fill asneeded.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required mainte-
nance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.

SRT MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this manual must be done at the times
or mileages specified to protect your vehicle warranty and ensure the best vehicle
performance and reliability. More frequent maintenance may be needed for vehicles
in severe operating conditions, such as dusty areas and very short trip driving.
Inspection and service should also be done anytime a malfunction is suspected.
The oil change indicator system will remind you that it is time to take your vehicle in
for scheduled maintenance.
The Driver Information Display (DID) will display an “Oil Change Required” message
and a single chime will sound, indicating that an oil change is necessary.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
NOTE:
• The oil change indicator message will not monitor the time since the last oilchange. Change your vehicle's oil if it has been six months since your last oil
change, even if the oil change indicator message is NOT illuminated.
• Change your engine oil more often if you drive your vehicle off-road for an extended period of time.
• Under no circumstances should oil change intervals exceed 6,000 miles (10,000 km) or six months, whichever comes first.
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Warning Lights” in “What To Do In Emergen-
cies” in this guide or “Driver Information Display (DID)” in “Understanding Your
Instrument Panel” in your Owners Manual on the DVD for further information.
At Each Stop For Fuel
• Check the engine oil level. Refer to “Maintenance Procedures/Engine Oil” in “Maintaining Your Vehicle” for further information.
• Check the windshield washer solvent and add if required.
