Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/snowflake” symbol on the tire sidewall.If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
tires only in sets of four; failure to do
so may adversely affect the safety
and handling of your vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer
to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.
Spare Tires — If Equipped
NOTE: For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire Service Kit”
in “In Case Of Emergency” for further information.
CAUTION!
Because of the reduced ground clearance, do not
take your vehicle through an automatic car wash
with a compact or limited use temporary spare
installed. Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And
Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear
axle of your vehicle. This spare tire may be used in the
tire rotation for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for the recom-
mended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use
only. You can identify if your vehicle is equipped with

a compact spare by looking at the spare tire description
on the Tire and Loading Information Placard located on
the driver ’s side door opening or on the sidewall of the
tire. Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation. Ex-
ample: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare
tire. Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares

installed to the vehicle. Inflate the collapsible tire using
the electric air pump before lowering the vehicle.
234 SERVICING AND MAINTENANCE

Do not install a wheel cover or attempt to mount a
conventional tire on the collapsible spare wheel, since
the wheel is designed specifically for the collapsible
spare tire.
WARNING!
Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to
the tread wear indicators, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings, which apply to your spare. Failure to do
so could result in spare tire failure and loss of
vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only.
This tire may look like the originally equipped tire on
the front or rear axle of your vehicle, but it is not. This
spare tire may have limited tread life. When the tread is
worn to the tread wear indicators, the temporary use
full size spare tire needs to be replaced. Since it is notthe same as your original equipment tire, replace (or
repair) the original equipment tire and reinstall on the
vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency
use only. This tire is identified by a label located on the
limited use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use
spare tire affects vehicle handling. Since it is not the
same as your original equipment tire, replace (or repair)
the original equipment tire and reinstall on the vehicle
at the first opportunity.
WARNING!
Limited use spares are for emergency use only.
Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than the speed listed on the limited use spare
wheel. Keep inflated to the cold tire inflation pres-
sures listed on your Tire and Loading Information

WARNING!(Continued)
Placard located on the driver ’s side B-Pillar or the
rear edge of the driver ’s side door. Replace (or
repair) the original equipment tire at the first op-
portunity and reinstall it on your vehicle. Failure to
do so could result in loss of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly
using mild (neutral Ph) soap and water to maintain
their luster and to prevent corrosion. Wash wheels with
the same soap solution recommended for the body of
the vehicle and remember to always wash when the
surfaces are not hot to the touch.
Your wheels are susceptible to deterioration caused by
salt, sodium chloride, magnesium chloride, calcium
chloride, etc., and other road chemicals used to melt ice
or control dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do not use harsh
chemicals or a stiff brush. They can damage the wheel’s
protective coating that helps keep them from corroding
and tarnishing.
CAUTION!
Avoid products or automatic car washes that use
acidic solutions or strong alkaline additives or
harsh brushes. Many aftermarket wheel cleaners
and automatic car washes may damage the wheel’s
protective finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car wash soap,
Mopar Wheel Cleaner or equivalent is recom-
mended.
When cleaning extremely dirty wheels including exces-
sive brake dust, care must be taken in the selection of
tire and wheel cleaning chemicals and equipment to
prevent damage to the wheels. Mopar Wheel Treatment
or Mopar Chrome Cleaner or their equivalent is recom-
mended or select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These prod-
ucts may damage the wheel’s protective finish.
Such damage is not covered by the New Vehicle

Limited Warranty. Only car wash soap, Mopar
Wheel Cleaner or equivalent is recommended.
NOTE: If you intend parking or storing your vehicle for
an extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the brakes
to remove the water droplets from the brake compo-
nents. This activity will remove the red rust on the
brake rotors and prevent vehicle vibration when brak-
ing.
Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat Wheels
CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives, or
polishing compounds. They will permanently dam-
age this finish and such damage is not covered by
the New Vehicle Limited Warranty. HAND WASH
ONLY USING MILD SOAP AND WATER WITH A
SOFT CLOTH. Used on a regular basis; this is all
that is required to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.
• Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on Rear Tires Only.
• Reduced size snow chains with a maximum projec-
tion of 7 mm beyond the tire profile can be fitted on
vehicles equipped with 235/40 R18 rear tire.
CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
•
Because of restricted traction device clearance be-
tween tires and other suspension components, it is
important that only traction devices in good condi-
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Remove
the damaged parts of the device before further
use.

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 con-
trolled conditions on specified government test sur-
faces 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, hydroplan-
ing, 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 controlled 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 perfor-
mance on the laboratory test wheel, than the mini-
mum required by law.WARNING!
The temperature grade for this tire is established
for a tire that is properly inflated and not over-
loaded. Excessive speed, under-inflation, or ex-
cessive loading, either separately or in combina-
tion, can cause heat buildup and possible tire
failure.

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 pos-
sible. The cost of such repairs is considered the
responsibility of the owner.
• If you carry special cargo such as chemicals, fertiliz-
ers, 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 Mopar Total Clean, 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.
