2010 JEEP GRAND CHEROKEE Owners Manual

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.
Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake discs, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
After driving off-road, completely inspect the underbody
of your vehicle. Check the tires, body structure, steering,
suspension and exhaust system for damage. Check
threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
Service Manual. Also check for accumulations of vegeta-
tion or brush that could become a fire hazard, or conceal
damage to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
392 MAINTAINING YOUR VEHICLE

CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants, and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service, to prevent excessive
wear.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near seacoast localities.
•Atmospheric fallout/industrial pollutants.
Washing
•
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MOPARCar Wash or a mild
car wash soap, and rinse the panels completely with
clear water.
7
MAINTAINING YOUR VEHICLE 393

•If insects, tar, or other similar deposits have accumu-
lated on your vehicle, use MOPARSuper Kleen Bug
and Tar Remover or equivalent to remove.
•Use a high quality cleaner wax, such as MOPAR
Cleaner Wax to remove road film, stains, and to
protect your paint finish. Take care never to scratch the
paint.
•Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
CAUTION!
•Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
(Continued)
CAUTION! (Continued)
•Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or removal of
paint and decals.
Special Care
•
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
•It is important that the drain holes in the lower edges
of the doors, rocker panels and tailgate must be kept
clear and open.
•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
394 MAINTAINING YOUR VEHICLE

•If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protective
coating, have your vehicle repaired as soon as pos-
sible. The cost of such repairs is considered the respon-
sibility of the owner.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use MOPARTouch 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 recommended. Do
not use oven cleaner. Avoid automatic 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 following man-
ner:
•Remove as much of the stain as possible by blotting
with a clean, dry towel.
7
MAINTAINING YOUR VEHICLE 395

•Blot any remaining stain with a clean, damp towel.
•For tough stains, apply MOPARTotal 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 equiva-
lent, 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 specifically recom-
mended 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.
Stubborn 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 condi-
tioner is not required to maintain the original condition.
396 MAINTAINING YOUR VEHICLE

WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas, they may cause respiratory 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 fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material 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 caution 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.
7
MAINTAINING YOUR VEHICLE 397

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 MOPARTotal 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.
