2012 JEEP GRAND CHEROKEE engine

CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift qual-
ity and/or torque converter shudder. Using a
transmission fluid other than the manufactur-
er’s recommended fluid will require more fre-
quent fluid and filter changes. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Special Additives
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes to aid in detecting fluid leaks. In
addition, avoid using transmission sealers as
they may adversely affect seals.CAUTION!
Do not use chemical flushes in your transmis-
sion as the chemicals can damage your trans-
mission components. Such damage is not
covered by the New Vehicle Limited Warranty.
Fluid Level Check – 3.6L And 3.0L Diesel
Engine
Routine fluid level checks are not required. For
this reason, the dipstick is omitted. Your autho-
rized dealer can check your transmission fluid
level using a special service dipstick.
If you notice fluid leakage or transmission mal-
function, have your authorized dealer check
the transmission fluid level. Operation with an
improper fluid level can greatly reduce the life
of your transmission.CAUTION!
• Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder.
Using a transmission fluid other than that
recommended by the manufacturer will re-
quire more frequent fluid and filter changes.
Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for fur-
ther information.
• The fluid level is preset at the factory and it
does not require adjustment under normal
operating conditions. If a transmission fluid
leak occurs, visit your authorized dealer
immediately. Severe damage to the trans-
mission may occur. Your authorized dealer
has the proper tools to adjust the fluid level
accurately.

Fluid Level Check – 5.7L Engine
Check the fluid level while the transmission is at
normal operating temperature. This occurs af-
ter at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot
be held comfortably between the fingertips.
To check the fluid level properly, the following
procedure must be used:
1. Operate the engine at idle speed and nor-
mal operating temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake, and press the
brake pedal.
4. Place the shift lever momentarily in each
gear position ending with the shift lever in
PARK.
5. Remove the dipstick, wipe it clean and
reinsert it until seated.6. Remove the dipstick again, and note the
fluid level on both sides. The fluid level should
be between the “HOT” (upper) reference holes
on the dipstick at normal operating tempera-
ture. The fluid level is only valid if there is a solid
coating of oil on both sides of the dipstick. If the
fluid is low, add as required into the dipstick
tube.
Do not overfill. After adding any quantity
of oil through the oil fill tube, wait a minimum of
two minutes for the oil to fully drain into the
transmission before rechecking the fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid
level should be between the two “COLD”
(lower) holes on the dipstick with the fluid at
approximately 70°F (21°C) (room tempera-
ture). If the fluid level is correctly estab-
lished at room temperature, it should be
between the “HOT” (upper) reference holes
when the transmission reaches 180°F
(82°C). Remember it is best to check the
level at the normal operating temperature.CAUTION!
Be aware that 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.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the
transmission after checking or replenishing
fluid, make certain 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.

Plastic is not as scratch-resistant as glass and
therefore different lens cleaning procedures
must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid wiping
with a dry cloth. To remove road dirt, wash with
a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate-
rial to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with MOPARGlass Cleaner or
any commercial household-type glass cleaner.
Never use an abrasive type cleaner. Use cau-
tion when cleaning inside rear windows
equipped with electric defrosters. Do not use
scrapers or other sharp instruments which may
scratch the elements.
When cleaning the rearview mirror, spray
cleaner on the towel or rag that you are using.
Do not spray cleaner directly on the mirror. Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When
cleaning the lenses, care must be taken to
avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap
solution may be used, but do not use high
alcohol content or abrasive cleaners. If soap is
used, wipe clean with a clean damp rag.
2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This
will weaken the fabric. Sun damage will also
weaken the fabric.
If the belts need cleaning, use MOPAR
Total
Clean, a mild soap solution, or lukewarm water.
Do not remove the belts from the vehicle to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn
or if the buckles do not work properly.FUSES

tains cartridge fuses and mini fuses. A descrip-
tion of each fuse and component may be

Fuel Selection – 3.0L Diesel Engine 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 dam-
age 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.
