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.
(Continued)
CAUTION! (Continued)
•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
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified fluid
for the flushing procedure.
Engine Oil
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 30 minutes after engine shutdown to
check the oil.
176 MAINTAINING YOUR VEHICLE
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 “ADD” mark.
The total capacity from the ADD mark to the Full mark is
2 qts (1.9L).
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
Never operate the engine with oil level below the “ADD”
mark or above the upper “SAFE” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends engine oils that are API CJ-4 certified and meet
the requirements of FCA LLC. Use MOPAR or an equiva-
lent oil meeting FCA Material Standard MS-10902. Prod-
ucts meeting Cummins CES 20081 may also be used. The
identification of these engine oils are typically located on
the back of the oil container.

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has been
certified by the American Petroleum In-
stitute (API). The manufacturer only rec-
ommends API Certified engine oils.
Oils with a high ash content may produce damaging
deposits on cylinder head valves and/or aftertreatment
system damage. A maximum sulfated ash content of 1.00
mass % is recommended for all oil used in the engine.
The same oil change interval is to be followed for synthetic
oil as for petroleum based oil. Also, synthetic oil must meet
the same performance specifications as petroleum oil.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is not
covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
In ambient temperatures above 0°F (-18°C), we recommend
you use SAE 15W-40 engine oil such as MOPAR, Shell
Rotella and Shell Rimula that meets FCA Material Standard
MS-10902 and the API CJ-4 engine oil category is required.
Products meeting Cummins CES 20081 may also be used.
The identification of these engine oils is typically located
on the back of the oil container.
In ambient temperatures below 0°F (-18°C), SAE 5W-40 we
recommend you use syntheticengine oil such as MOPAR,
Shell Rotella and Shell Rimula that meets FCA Material
Standard MS-10902 and the API CJ-4 engine oil category is
required.
CAUTION!
Failure to use SAE 5W-40 synthetic engine oil in
ambient temperatures below 0°F (-18°C) could result in
severe engine damage.
178 MAINTAINING YOUR VEHICLE
Engine oil not designated by the FCA or Cummins Material
Standards and API CJ-4 should not be used, as engine and
exhaust system durability may be compromised. The en-
gine oil filler cap also shows the recommended engine oil
viscosity for your engine. For information on engine oil
filler cap location, refer to “Engine Compartment” in
“Maintaining Your Vehicle” for further information.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met and the recommended main-
tenance intervals for oil and filter changes are followed.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion 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.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information. The engine
oil filter should be changed at every engine oil change.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service sta-
tion or governmental agency for advice on how and where
used oil and oil filters can be safely discarded in your area.7

CAUTION!
•Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate container.
• Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility debris could be
introduced into the fuel filter during this action. It is
best to install the filter dry and allow the in-tank lift
pump to prime the fuel system.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn counterclockwise and completely drain fuel and water into the approved
container.

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.
(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a accident.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in an accident.
Clutch Hydraulic System
The clutch hydraulic system is a sealed maintenance-free
system. In the event of leakage or other malfunction, the
system must be replaced.

7. Remove the dipstick again and note the fluid level onboth sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube to
bring it to the proper level. Do not overfill.Use ONLY
the specified fluid (see Fluids, Lubricants, and Genuine
Parts for fluid specifications). After adding any quan-
tity of oil through the dipstick tube, wait a minimum of
two minutes for the oil to fully drain into the transmis-
sion before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be be-
tween the two “COLD” (lower) holes on the dipstick with
the fluid at 60-70°F / 16-21°C for 68RFE transmission, or
68-86°F / 20-30°C for AS69RC transmission. Only use the
COLD region of the dipstick as a rough reference when
setting the fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as required,
once the transmission reaches normal operating tempera-
ture.CAUTION!
If the fluid temperature is below 50°F (10°C) it may not
register on the dipstick. Do not add fluid until the
temperature is elevated enough to produce an accurate
reading. Run the engine at idle, in PARK, to warm the
fluid.
8. Reinsert the dipstick. Check for leaks. Release the park- ing brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is normal
for the dipstick cap to spring back slightly from its fully
seated position, as long as its seal remains engaged in the
dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
In addition, change the fluid and filter(s) if the fluid
becomes contaminated (with water, etc.), or if the transmis-
sion is disassembled for any reason.
