2012 JEEP GRAND CHEROKEE oil change

Overloading your vehicle, long trips in very hot
weather, and driving on bad roads may result in
greater wear.
Life Of TireThe service life of a tire is dependent upon
varying factors including but not limited to:
•Driving style
• Tire pressure
• Distance driven
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have an accident resulting in serious
injury or death.
Keep unmounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease and gasoline.
Replacement TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected regularly for wear and correct inflation
pressure. The manufacturer strongly recom-
mends that you use tires equivalent to the
originals in quality and performance when re-
placement is needed (see section on tread
wear indicators). Failure to use equivalent re-
placement tires may adversely affect the safety,
handling and ride of your vehicle. We recom-
mend that you contact your local authorized
dealer on any questions you may have on tire
specifications or capability.
WARNING!
• Do not use a tire, wheel size or rating other
than that specified for your vehicle. Some
combinations of unapproved tires and
wheels may change suspension dimen-
sions and performance characteristics, re-
sulting in changes to steering, handling,
and stress to steering and suspension
components. You could lose control and
have an accident resulting in serious injury
or death. Use only the tire and wheel sizes
with load ratings approved for your vehicle.
• Never use a tire smaller than the minimum
tire size listed on your vehicle’s tire placard
unless explicitly instructed to do so by the
vehicle manufacturer (reference tire chain
information in this manual). Using an
under-sized tire could result in tire over-
loading and failure.
•
Failure to equip your vehicle with tires having
adequate speed capability can result in sud-
den tire failure and loss of vehicle control.

CAUTION!
•Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized 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 intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by the
New Vehicle Limited Warranty. If a flush is
needed because of component malfunc-
tion, use only the specified fluid for the
flushing procedure.Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at
the correct level. The best time to check the
engine oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the SAFE level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine. Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Engine Oil Selection – Non ACEA
Categories
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils
that are API certified and meet the require-
ments of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol
means that the oil
has been certified
by the American
Petroleum Institute
(API). The manu-

and the recommended maintenance intervals
for oil and filter changes are followed.
Materials Added To Engine OilsDo not add supplemental materials, other than
leak detection dyes, to the engine oil. Engine oil
is an engineered product, and its performance
may be impaired by supplemental additives.
Disposing Of Used Engine Oil And
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 local authorized dealer, service
station, or governmental agency for advice on
how and where used oil and oil filters can be
safely discarded in your area.
Engine Oil FilterThe engine oil filter should be replaced with a
new filter at every oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow
type disposable oil filter. Use a filter of this type
for replacement. The quality of replacementfilters varies considerably. Only high-quality
filters should be used to assure most efficient
service. MOPAR
engine oil filters are high-
quality oil filters and are recommended.
Engine Air Cleaner FilterRefer to the “Maintenance Schedule” for the
proper maintenance intervals.
WARNING!
The air induction system (air cleaner, hoses,
etc) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no one
is near the engine compartment before start-
ing the vehicle with the air induction system
(air cleaner, hoses, etc.) removed. Failure to
do so can result in serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to assure most efficient service. MOPAR
engine air cleaner filters are
a high quality filter and are recommended.
Maintenance-Free BatteryYour vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water.
• Battery gas is flammable and explosive.
Keep flame or sparks away from the bat-
tery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
• Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash hands after handling.

4. Install the wiper blade pivot pin into the
wiper blade holder at the end of the wiper arm,
and firmly press the wiper blade until it snaps
into place.
5. Lower the wiper blade and snap the pivot
cap into place.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating information can be found on
most washer fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing CO, refer to “Safety Tips/
Exhaust Gas” in “Things To Do Before Starting
Your Vehicle” for further information.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty 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 sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-quired” will be displayed in the EVIC and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11 200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
•
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
6 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 ex-
tended period of time. •
Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
