WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
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 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.
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 recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

Extreme Cold Weather
The engine block heater is a resistance heater installed in the
water jacket of the engine. It requires a 110–115 Volt AC
electrical outlet with a grounded, three-wire extension cord.
Its use is recommended for environments that routinely fall
below -10°F (-23°C). It should be used when the vehicle has
not been running overnight or longer periods and should be
plugged in two hours prior to start. Its use is required for
cold starts with temperatures under -20°F (-28°C).
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer.
• A 12 Volt heater built into the fuel filter housing aids in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A Diesel Pre-Heat system both improves engine starting
and reduces the amount of white smoke generated by a
warming engine.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed, the
engine should start in all conditions and no type of starting
fluid should be used.

Uphill Grade Maximum GCWR Hot2.5
NOTE: Under certain conditions the engine fan will run
after the engine is turned off. These conditions are under
high load and high temperature conditions.
Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
• 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.
• Air Conditioning — Turn it off temporarily.
NOTE: If the coolant temperature is too high the A/C will
automatically turn off.
Do Not Operate The Engine With Low Oil Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as soon
as possible. A chime will sound when the light turns on.
NOTE: Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
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.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealership or qualified repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle

CAUTION! (Continued)
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified fluid
for the flushing procedure.
Engine Oil
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer recom-
mends engine oils that meet the requirements of FCA
Material Standard MS-10902, and that are API CJ-4 certified
and meet the requirements of FCA LLC.
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check the
oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tempera-
ture, then wait for five minutes after engine shutdown to
check the oil.

1 — MAX Mark
2 — MIN Mark
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil only
when the level on the dipstick is below the “MIN” mark.
The total capacity from the MIN mark to the MAX mark is
1.3 qts (1.2 L).
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
NOTE: It is possible for your oil level to be slightly higher
than a previous check. This would be due to diesel fuel that
may temporarily be in the crankcase due to operation of
the diesel particulate filter regeneration strategy. This fuel
will evaporate out under normal operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.

Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained, flushed
and refilled with fresh coolant. Check the front of the A/C
condenser (if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the A/C
condenser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.With the engine at normal operating temperature (but not
running), check the cooling system pressure cap for proper
vacuum sealing by draining a small amount of engine
coolant (antifreeze) from the radiator drain cock. The
radiator drain cock is located in the lower radiator tank. If
the cap is sealing properly, the engine coolant (antifreeze)
will begin to drain from the coolant expansion bottle. DO
NOT REMOVE THE COOLANT PRESSURE CAP WHEN
THE COOLING SYSTEM IS HOT.
Cooling System — Drain Flush And Refill
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.

Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based engine coolant
(antifreeze) in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle. •
Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
68 MAINTAINING YOUR VEHICLE

Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air rap-
idly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through another
hose to the intake manifold of the engine. This cooling
process enables more efficient burning of fuel resulting in
fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and radiator
clean and free of debris. Periodically check the hoses
leading to and from the charge air cooler for cracks or loose
clamps resulting in loss of pressure and reduced engine
performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immediately
if the “Brake System Warning Light” indicates system
failure.The brake master cylinder has a translucent plastic reser-
voir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
