2012 JEEP GRAND CHEROKEE warning

CAUTION!
•It is essential when replacing the cables on
the battery that the positive cable is at-
tached to the positive post, and the nega-
tive cable is attached to the negative post.
Battery posts are marked (+) positive and
(-) negative and identified on the battery
case.
• If a “fast charger” is used while battery is in
the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to
provide starting voltage.
Air Conditioner MaintenanceFor best possible performance, your air condi-
tioner should be checked and serviced by an
authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt condition should also be checked at
this time.
CAUTION!
Do not use chemical flushes in your air con-
ditioning system as the chemicals can dam-
age your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
•Use only refrigerants and compressor lubri-
cants approved by the manufacturer for
your air conditioning system. Some unap-
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
• The air conditioning system contains refrig-
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced repairman. NOTE:
Use only manufacturer approved A/C Sys-
tem Sealers, Stop Leak Products, Seal Con-
ditioners, Compressor Oil, and Refrigerants.
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency (EPA) and is
an ozone-saving product. However, the manu-
facturer recommends that air conditioning ser-
vice be performed by authorized dealers or
other service facilities using recovery and recy-
cling equipment.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically
with a lithium based grease, such as MOPAR
Spray White Lube or equivalent to assure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating excess
oil and grease should be removed. Particular

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.
307

CAUTION!
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your ve-
hicle serviced promptly. Continued operation
of your vehicle with a severe malfunction
could cause the converter to overheat, result-
ing in possible damage to the converter and
vehicle.
NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such ma-
terials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tuneup to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
• Do not shut off the engine or interrupt the
ignition, when the transmission is in gear and
the vehicle is in motion.
• Do not try to start the engine by pushing or
towing the vehicle. •
Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
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 or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves,
308

When adding engine coolant (antifreeze):
•
The manufacturer recommends using MOPAR
Antifreeze/ Coolant 5–Year/100,000 Mile For-
mula HOAT (Hybrid Organic Additive Technol-
ogy) or equivalent.
• Mix a minimum solution of 50% HOAT engine
coolant (antifreeze) and distilled water. Use
higher concentrations (not to exceed 70%) if
temperatures below -34°F (-37°C) are antici-
pated.
• Use only high purity water such as distilled
or deionized water when mixing the water/
engine coolant (antifreeze) solution. The use
of lower quality water will reduce the amount
of corrosion protection in the engine cooling
system.
Please note that it is the owner’s responsibility
to maintain the proper level of protection
against freezing according to the temperatures
occurring in the area where the vehicle is
operated.
NOTE:
Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (an- tifreeze) and will require more frequent en-
gine coolant (antifreeze) changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to the
radiator from the coolant recovery tank.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
•
The warning words DO NOT OPEN HOT
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not remove
the pressure cap while the system is hot or
under pressure.
(Continued)
WARNING!(Continued)
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant
(antifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals
and children, do not store ethylene glycol-
based engine coolant (antifreeze) in open con-
tainers 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.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the engine coolant
(antifreeze) level is adequate. With the engine
idling, and warm to normal operating tempera-
ture, the level of the engine coolant (antifreeze)
in the bottle should be between the ranges
indicated on the bottle.
310

The radiator normally remains completely full,
so there is no need to remove the radiator cap,
unless checking for engine coolant (antifreeze)
freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, it should
be added to the coolant bottle. Do not overfill.
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 re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) 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 recovery bottle.
• Check engine coolant (antifreeze) freeze
point in the radiator and in the coolant recov-
ery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant
recovery bottle must also be protected
against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, or if the level in the
coolant recovery bottle does not drop when
the engine cools, the cooling system should
be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concen-
tration at 50% HOAT engine coolant (anti-
freeze) (minimum) and distilled water for
proper corrosion protection of your engine,
which contains aluminum components.
• Make sure that the radiator and coolant
recovery bottle hoses are not kinked or ob-
structed. •
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 nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory cooling performance, poor gas mileage,
and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be peri-
odically inspected. Refer to the “Maintenance
Schedule” for the proper maintenance inter-
vals.
WARNING!
Riding the brakes can lead to brake failure
and possibly an accident. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
311

Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warn-
ing lamp indicates system failure.
The brake master cylinder has a translucent
plastic reservoir. On the outboard side of the
reservoir, there is a “MAX” dot and a “MIN” dot.
The fluid level must be kept within these two
dots. Do not add fluid above the MAX mark,
because leakage may occur at the cap.
With disc brakes, the fluid level can be ex-
pected to fall as the brake linings wear. How-
ever, 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 “Maintaining 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 performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master
cylinder reservoir.
• To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed con-
tainer. Keep the master cylinder 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 braking, resulting in sud-
den brake failure. This could result in a
accident.
(Continued)WARNING!(Continued)
• 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 con-
taminate the brake fluid. Brake seal com-
ponents could be damaged, causing partial
or complete brake failure. This could result
in an accident.
Front/Rear Axle FluidFor normal service, periodic fluid level checks
are not required. When the vehicle is serviced
for other reasons the exterior surfaces of the
axle assembly should be inspected. If gear oil
leakage is suspected inspect the fluid level.
Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.

•Use MOPAR Touch Up Paint or equivalent
on scratches or chips as soon as possible.
Your authorized dealer has touch up paint to
match the color of your vehicle.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum
and chrome-plated wheels should be cleaned
regularly with a mild soap and water to prevent
corrosion. To remove heavy soil, use MOPAR
Wheel Cleaner or select a nonabrasive, non-
acidic cleaner. Do not use scouring pads, steel
wool, a bristle brush or metal polishes. Only
MOPAR cleaners or equivalent are recom-
mended. Do not use oven cleaner. Avoid auto-
matic car washes that use acidic solutions or
harsh brushes that may damage the wheels’
protective finish.
Stain Repel Fabric Cleaning Procedure – If
Equipped
Stain Repel seats may be cleaned in the follow-
ing manner:
• Remove as much of the stain as possible by
blotting with a clean, dry towel.
• Blot any remaining stain with a clean, damp
towel. •
For tough stains, apply MOPAR Total Clean
or a mild soap solution to a clean, damp
cloth and remove the stain. Use a fresh,
damp towel to remove soap residue.
• For grease stains, apply MOPAR Multi-
Purpose Cleaner or equivalent to a clean,
damp cloth and remove the stain. Use a
fresh, damp towel to remove soap residue.
• Do not use any harsh solvents or any other
form of protectants on Stain Repel products.
Interior Care
Use MOPAR Total Clean or equivalent to clean
fabric upholstery and carpeting.
Interior Trim should be cleaned starting with a
damp cloth, a damp cloth with MOPAR Total
Clean or equivalent, then MOPAR Spot & Stain
Remover or equivalent, if absolutely necessary.
Do not use harsh cleaners or Armor All . Use
MOPAR Total Clean or equivalent to clean
vinyl upholstery.
Leather Seat Care And Cleaning
MOPAR Total Clean or equivalent is specifi-
cally recommended for leather upholstery. Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and should
be removed promptly with a damp cloth. Stub-
born soils can be removed easily with a soft
cloth and MOPAR
Total Clean or equivalent.
Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do
not use polishes, oils, cleaning fluids, solvents,
detergents, or ammonia-based cleaners to
clean your leather upholstery. Application of a
leather conditioner is not required to maintain
the original condition.
WARNING!
Do not use volatile solvents for cleaning pur-
poses. Many are potentially flammable, and if
used in closed areas, they may cause respi-
ratory harm.
Cleaning Headlights
Your vehicle has plastic headlights that are
lighter and less susceptible to stone breakage
than glass headlights.
317

•Anytime you store your vehicle, or keep it out
of service (i.e. vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
