Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on Euro -
pean design standards. Tires designed to this
standard have the tire size molded into the side -
wall beginning with the section width. The letter
"P" is absent from this tire size designation.
Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based on
US design standards. The size designation for
LT-Metric tires is the same as for P-Metric tires
except for the letters “LT” that are molded into
the sidewall preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
High flotation tire sizing is based on US design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5

386SERVICING AND MAINTENANCE
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed Ú page 385. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
For more information relating to the Load Index
and Speed Symbol of a tire Ú page 376.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use all
season tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if roads
are covered with ice or snow. For more
information, contact an authorized dealer.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre -
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.

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.
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 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. Use precautions to not
scratch the paint.
Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin out
the paint finish.
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.
If your vehicle is damaged due to a collision or
similar cause that destroys the paint and protec -
tive coating, have your vehicle repaired as soon
as possible.
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. An authorized dealer has
touch up paint to match the color of your
vehicle.
CAUTION!
Do not use abrasive or strong cleaning mate -
rials 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.

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.
Clean with a wet soft cloth. 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 cloth. Dry with a soft cloth.
LEATHER SURFACES
Mopar® Total Clean is specifically 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. Stubborn soils can be
removed easily with a soft cloth and Mopar® Total
Clean. 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.
NOTE:If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye
transfer more so than darker colors. The leather is
designed for easy cleaning, and the manufacturer
recommends Mopar® Total Care leather cleaner
applied on a cloth to clean the leather seats as
needed.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 caution when
cleaning the inside rear window equipped with
electric defrosters or windows equipped with radio
antennas. Do not use scrapers or other sharp
instruments that may scratch the elements.
When cleaning the rear view mirror, spray cleaner
on the towel or cloth that you are using. Do not
spray cleaner directly on the mirror.
CAUTION!
Do not use Alcohol and Alcohol-based and/or
Ketone based cleaning products to clean leather
upholstery, as damage to the upholstery may
result.
