2017 JEEP GRAND CHEROKEE Owners Manual

CAUTION!(Continued)
•Observe the traction device manufacturer ’s instruc-
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturer ’s if it is
less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on On/Off-Road type tires.
Rotation will increase tread life, help to maintain mud,
snow, and wet traction levels, and contribute to a smooth,
quiet ride.
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals. More frequent rotation is permissible if
desired. The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed. NOTE:
The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward-cross”
shown in the following diagram.

DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire’s manufacturer in
each category is shown on the sidewall of the tires on your
vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on the
wear rate of the tire when tested under controlled condi-
tions on a specified government test course. For example, a
tire graded 150 would wear one and one-half times as well
on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions of
their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices,
and differences in road characteristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire’s ability to stop on
wet pavement, as measured under controlled conditions onspecified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.
Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat
and its ability to dissipate heat, when tested under con-
trolled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the
tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all passenger
vehicle tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel, than the
minimum required by law.
496 SERVICING AND MAINTENANCE

WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded. Ex-
cessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.
STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
•Park your vehicle in a covered, dry and possibly airy
location the windows open slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every 30 days.
• Clean and protect the painted parts by applying protec-
tive waxes. •
Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across
dirty surfaces. Do not use plastic sheeting which will not
allow the evaporation of moisture present on the surface
of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar)
higher than recommended on the tire placard and check
it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is stationary for two
weeks or more, run idle the engine for approximately
five minutes, with the air conditioning system on and
high fan speed. This will ensure a proper lubrication of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.

SERVICING AND MAINTENANCE 497

NOTE:When the vehicle has not been started or driven for
at least 30 days, an Extended Park Start Procedure is
required to start the vehicle. Refer to “Starting Procedures”
in “Starting And Operating” for further information.
CAUTION!
Before removal of the positive and negative terminals
to the battery, wait at least a minute with ignition
switch in the OFF position and close the drivers door.
When reconnecting the positive and negative terminals
to the battery be sure the ignition switch is in the OFF
position and the drivers door is closed.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geographic
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. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather and other
extreme conditions will have an adverse effect on paint,
metal trim, and underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance 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.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights 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.
498 SERVICING AND MAINTENANCE

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 material to clean the lenses.
Preserving The Bodywork
Washing
•Wash your vehicle regularly. Always wash your vehicle
in the shade using MOPAR Car Wash, or a mild car wash
soap, and rinse the panels completely with clear water.
• If insects, tar, or other similar deposits have accumulated
on your vehicle, use MOPAR Super Kleen Bug and Tar
Remover 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 that will scratch
metal and painted surfaces.
• 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 trunk 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.
• If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The cost
of such repairs is considered the responsibility of the
owner.

•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure 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 MOPAR Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint to
match the color of your vehicle.
INTERIORS
Seats And Fabric Parts
Use MOPAR Total Clean to clean fabric upholstery and
carpeting.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in closed
areas they may cause respiratory harm.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical solvents
or abrasive cleaners. This will weaken the fabric. Sun
damage can also weaken the fabric.
If the belts need cleaning, use 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.
WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.).
