SAE 5W-30 MOPAR or Shell Rotella that meets FCA Material Standard MS-10902 and the API CJ-4 or ACEA E9/E7 or ACEA A3/B4 engine oil category is required.

Mopar p/n 68001332PA, MSRP $9.50/quart

WARNING: Before checking the engine oil level turn the engine off and wait 15 minutes for the oil to return to the oil pan.

WARNING: Any time the oil is drained and filled it is critical to wait 15 minutes before starting the engine.

NOTE:The manufacturer strongly recommends against the addition of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its performance may be impaired by supplemental additives.

NOTE: It may take 30 minutes or longer for the engine oil in the oil filter housing to completely drain back into the engine. The oil will only drain back into the engine through the oil pump gears. When servicing the oil filter, vehicle maintenance personnel need to be made aware that the residual oil in the housing may spill from the housing when the new filter is installed.

To prevent residual oil in the housing from spilling when the new filter is installed either use a suction gun to remove any residual oil left in the housing or wait about 30 minutes allow the oil to drain back into the engine.

NOTE: Based on engine operating conditions, the oil change indicator message will illuminate. This means that service is required for your vehicle. Operating conditions such as frequent short trips, trailer tow, extremely hot or cold ambient temperatures, and Biodiesel fuel usage will influence when the “Oil Change Required” message is displayed. Severe Operating Conditions can cause the change oil message to illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km).

Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km) or 12 months, whichever comes first.

WHEN USING BIODIESEL BLENDS GREATER THAN 5% (B6 TO B20) – Under no circumstances should oil change intervals exceed 8,000 miles (12,875 km) or 6 months, whichever comes first.

Hemi engine Oil and Filter change directions

(4WD/AWD Grand Cherokees only)

The transfer case operates with an open center differential dividing engine torque 50 percent torque to the front axle and 50 of torque to the rear axle.

The Brake Traction Control System, which combines standard ABS and Traction Control, provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction.

Operation

Full-time 4-wheel drive distributes torque to all wheels under all conditions. The transfer case center differential divides torque to the front and rear axles, while also allowing the driveshafts to rotate at different speeds to account for front and rear wheels traveling different distances while turning. Given that the drive shafts can rotate at different speeds, the vehicle can remain in full-time 4-wheel drive mode indefinitely – even on dry pavement – without threat of damage to the drivetrain.

The vehicle uses Brake Traction Control to modulate the torque from one wheel to another across each axle and the transfer case.

Mopar® p/n 05127382AA (1 quart)

Drain/Fill plug torque: 16-21 ft.-Lbs.

Operation

Normal All-Wheel Drive allows front and rear wheels to rotate at different speeds on all road surfaces. The “SVC 4WD” warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required.

Proper operation of all-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case.

The DTCM (Drive Train Control Module) is an electronic module that controls the shifting of the 4WD “Active on Demand” MP3010 single speed transfer case.

For added traction capability when traversing steep grades, rough terrain or extremely poor traction surfaces, the transfer case includes a 4WD Low mode. This second speed gear multiplies engine torque 2.72 times and locks the clutch pack for maximum traction.

Electric shifting between 4WD AUTO and 4WD Low is effected with a console-mounted switch. A pushpin button is used to shift to Neutral mode.

Operation

Controls for the MP3023 transfer case active clutch (torque biasing device) are located in the Drive Train Control Module (DTCM) and communicated on the Controller Area Network (CAN) C bus. The DTCM monitors multiple vehicle sensors to anticipate conditions which may result in wheel slip or reduced performance and preemptively adjusts torque split to front and rear axles as needed.

The DTCM also compares wheel speeds at the front and rear axles to detect wheel slippage. A complete vehicle dynamics model, or algorithm, calculates slip at each tire for given vehicle-operating conditions. When wheel slip is detected, pressure applied to the transfer case clutch pack can be increased or decreased to apply increased torque to the axle with higher traction.

The transfer case operates in active full-time four-wheel drive (4WD AUTO) unless the driver chooses 4WD Low, or Neutral.

The electronically controlled wet clutch pack uses an electric motor to actuate an internal gear train, clutch cam, and low range barrel cam. The clutch cam actuates the clutch levers that apply normal force to the multi-disc wet clutch pack. The clutch discs are alternately splined to the front and rear drive shafts. When normal force is applied to this clutch pack, torque is transferred to equalize speed differences between front and rear axles.

Transfer of torque from one wheel to the other on an axle is accomplished by using Brake Traction Control. Under the right conditions the vehicle can be driven by just one wheel.

Standard Electronic Stability Program (ESP) works with the four-wheel drive system to enhance traction and control through three new features: Hill Descent, Hill Start Assist and Trailer Sway Control.

• ATF+4 MUST always be used in vehicles that were originally filled with ATF+4.
• ATF+4 is compatible with ATF+3 and can be used to top off vehicles that currently have ATF+2 or ATF+3.
• DO NOT use ATF+2 or ATF+3 to top off vehicles that have ATF+4 fluid

FLUID ADDITIVES:DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks. Various “special” additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been supported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of transmission “sealers” should also be avoided, since they may adversely affect the integrity of transmission seals.

Filter: (internal, flat) p/n 52108325AA

14 qts. (overhaul)

Filter # 1 (internal, flat):
2WD – Primary filter: p/n 5015267AD
($43.45 MSRP)

4WD – Primary filter: p/n 5013470AE
($42.50 MSRP)

Filter # 2 (internal, round):
All – Cooler return filter: p/n 4799662AB*
($16.95 MSRP)
*superseded by 05179267AD filter package ($22.60 MSRP)

NOTE:
It has been discovered that the 4799662AB cooler return filter (-AB version only!) can allow the torqueconverter to drainback. When the vehicle is started, the air in the T/C is compressed and after passing though the cooler can be directed to the sump filter. The compressed air has the ability to split the filter.

If the cooler return filter is marked with P/N 4799662AB, replace both filters. If the cooler return filter has no part number marking, or is marked 4799662AC (or later), replace only the sump filter.

Mopar Antifreeze/Coolant 5-year/100,000 mile formula
p/n 68048953AB (formerly 5066386AA)
MSRP $23.95/gallon.

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color (red/orange) or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Notes and cautions:

The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.

Avoid non-HOAT mixtures, such as Prestone 50/50, that claim they can be used in vehicles of “all makes, all models”.

Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.

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 cooling performance, poor gas mileage, and increased emissions.

CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.

CAUTION: Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Chrysler Corporation LLC. has released a new engine coolant for 2013 model year vehicles and beyond.

Mopar Antifreeze/Coolant 10-year/150,000 mile formula
p/n 68163848AB (concentrate) / p/n 68163849AB (50/50 mixture)
MSRP $25.70/gallon (concentrate) / MSRP $19.45/gallon (50/50 mixture)

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, or the equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called OAT, for Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Notes and cautions:

The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.

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 cooling performance, poor gas mileage, and increased emissions.

OAT coolant is purple in color. It cannot be mixed with other types of coolant including Chrysler’s existing HOAT coolant and only should only be mixed with approved OAT coolant of the same color. Maintenance of the cooling system is not required unless a repair has been made with loss of coolant or the coolant has been contaminated.

CAUTION: Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Technology (HOAT) engine coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, it should be replaced with the specified engine coolant (antifreeze) as soon as possible.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Use good quality diesel fuel from a reputable supplier in your vehicle. The manufacturer requires that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the emissions control system. For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide good performance.

If the vehicle is exposed to extreme cold (below 20F or -7C), or is required to operate at colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection from fuel gelling or wax-plugging of the fuel filters. This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM specification D-975.

Gasoline:

3.6L, 5.7L, 6.2L and 6.4L

NOTE: DO NOT use gasolines containing Methanol or E85 Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components.

87 octane Regular unleaded
(3.6L V6 and 5.7L V8 Hemi)

89 octane Mid-grade unleaded
(5.7 V8 Hemi, recommended for maximum performance)

91 octane (or higher) Premium (R+M)/2 recommended
(6.2L and 6.4L V8 Hemi)

NOTE: The use of Premium gasoline is NOT recommended for the 3.6L or 5.7L engines. Under normal conditions, the use of Premium gasoline will not provide a benefit over high quality Regular and Mid-grade gasoline, and in some circumstances may result in poorer performance.
