2010 JEEP GRAND CHEROKEE warning

CAUTION!(Continued)
• Do not use water alone or alcohol based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or antirust
products, as they may not be compatible
with the engine coolant (antifreeze) and
may plug the radiator.
• This vehicle has not been designed for use
with Propylene Glycol-based engine cool-
ant (antifreeze). Use of Propylene Glycol-
based engine coolant (antifreeze) is not
recommended.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (antifreeze) that allows extended
maintenance intervals. This engine coolant (an-
tifreeze) can be used up to 5 Years or
105,000 miles (168 000 km) before replace-
ment. To prevent reducing this extended main-
tenance period, it is important that you use the
same engine coolant (antifreeze) throughout the
life of your vehicle. Please review these recom-
mendations for using Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze).
When adding engine coolant (antifreeze):
•
The manufacturer recommends using MO-
PA R Antifreeze/ Coolant 5–Year/100,000 Mile
Formula HOAT (Hybrid Organic Additive
Technology) 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.

281

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. 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.
282

•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. 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 labeled 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)
283

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. Front Axle Fluid Level Check
The front axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not over tighten the plugs as it could
damage them and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m) on
axles with aluminum housings. The rear axle fill
and drain plugs should be tightened to 22 to
52 ft lbs (30 to 70 N·m) on axles with cast iron
housings.
CAUTION!
Do not over tighten the plugs as it could
damage then and cause them to leak.
Selection of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid
leak is found, the transfer case fluid level can
be checked by removing the filler plug located
on the back side of the transfer case. The fluid
level should be at the bottom edge of the filler
plug hole when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole, until it runs out of the
hole, when the vehicle is in a level position.
Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and
fill plugs is 15 to 25 ft lbs (20 to 34 N·m).
284

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.
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 MOPAR
Glass 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 tissue.
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.
Replace the belts if they appear frayed or worn
or if the buckles do not work properly.
Dry with a soft tissue.

•Or, disconnect the negative cable from the
battery.
• 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.

BULB REPLACEMENT
High Intensity Discharge Headlamps
(HID) – If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and
the key removed. Because of this, you should
not attempt to service a headlamp bulb your-
self. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb
sockets of High Intensity Discharge (HID)
headlamps when the headlamp switch is
turned ON. It may cause serious electrical
shock or electrocution if not serviced properly.
See your authorized dealer for service.
NOTE:
On vehicles equipped with High Intensity
Discharge (HID) headlamps , when the head-
lamps are turned on, there is a blue hue to
the lamps. This diminishes and becomes

Maintenance Schedule – Diesel
Engine
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your dealer-
ship know your vehicle best, and have access
to factory trained information, genuine MO-PA R
parts, and specially designed electronic
and mechanical tools that can help prevent
future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
Under no circumstances should oil change
intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
At Each Stop for Fuel
• Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
Check the fluid levels of the coolant reser-
voir, brake master cylinder, and power steer-
ing and add as needed.
• Check all lights and other electrical items for
correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
