Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. Four primary areas are
affected by improper tire pressure:
Safety and Vehicle Stability
Economy
Tread Wear
Ride Comfort
Safety
Warning!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result in
tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Both under-inflation and over-inflation
affect the stability of the vehicle and can
produce a feeling of sluggish response or
over responsiveness in the steering.
Note:
Unequal tire pressures from side to
side may cause erratic and
unpredictable steering response.
Unequal tire pressure from side to
side may cause the vehicle to drift left or
right.
Fuel Economy
Underinflated tires will increase tire
rolling resistance resulting in higher fuel
consumption.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and
reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear
edge of the driver's side door.
At least once a month:
Check and adjust tire pressure with a
good quality pocket-type pressure gauge.
Do not make a visual judgement when
determining proper inflation. Tires may
look properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or
visible damage.
Caution!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the valve stem.
Inflation pressures specified on the
placard are always “cold tire inflation
pressure”. Cold tire inflation pressure is
defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of
three hours. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire
sidewall.
233

Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation. DO
NOT reduce this normal pressure build up
or your tire pressure will be too low.
Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditionsare such that the vehicle can be driven at
high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer for
recommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Recommended Cold Tire Inflation
Pressures
For vehicle speeds below 100 mph
(160 km/h), recommended cold tire
inflation pressures are listed on the TireAnd Loading Information Placard located
on driver’s side B-Pillar or the rear edge
of the driver's side door.
When driving at speeds 100 mph
(160 km/h) and above, increased tire
pressures and reduced vehicle loading
are required for high-speed vehicle
operation.
For driving speeds above 100 mph
(160 km/h) recommended cold tire
inflation pressures are listed below
under "High Speed Tire Inflation
Pressure". Vehicle loading condition must
not exceed 688 lbs. (312 kg) (driver +
three passengers + 88 lbs. (40kg)
luggage).
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision.

Radial Ply Tires
Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability could
cause a collision. Always use radial ply tires
in sets of four. Never combine them with
other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when
flat.
The damage is only on the tread
section of your tire (sidewall damage is
not repairable).
The puncture is no greater than a ¼ of
an inch (6 mm).
Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat tires
that have experienced a loss of pressure
should be replaced immediately with
another Run Flat tire of identical size and
service description (Load Index and
Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to
drive 50 miles (80 km) at 50 mph
(80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat
mode it has limited driving capabilities
and needs to be replaced immediately. A
Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer
while a tire is in the run flat mode.
See the tire pressure monitoring section
for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's
wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously
without stopping.
235

Warning!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin
your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds
continuously when you are stuck, and do not
let anyone near a spinning wheel, no matter
what the speed.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in
determining when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves. They willappear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced.
Refer to “Replacement Tires” in this
section for further information.
Life Of Tire
The service life of a tire is dependent
upon varying factors including, but not
limited to:
Driving style.
Tire pressure - Improper cold tire
inflation pressures can cause uneven
wear patterns to develop across the tire
tread. These abnormal wear patterns will
reduce tread life, resulting in the need for
earlier tire replacement.
Distance driven.
Performance tires, tires with a speed
rating of V or higher, and Summer tires
typically have a reduced tread life. Rotation
of these tires per the vehicle scheduled
maintenance is highly recommended.
Warning!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.
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. Refer to the
paragraph on “Tread Wear Indicators” in
this section. 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.
See the Tire Sizing Chart example found
in the “Tire Safety Information” section of
this manual for more information relating
to the Load Index and Speed Symbol of a
tire.
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

SERVICING AND MAINTENANCE

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 not the 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 originalequipped 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 pressures listed on
your Tire and Loading Information 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 opportunity 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 recommended.
When cleaning extremely dirty wheels
including excessive 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
recommended or select a non-abrasive,
non-acidic cleaner for aluminum or
chrome wheels.
238
SERVICING AND MAINTENANCE

Caution!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven cleaner.
These products 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 components. This activity will
remove the red rust on the brake rotors
and prevent vehicle vibration when
braking.
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 damage 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 Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, 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 45°F (7°C) or if roads are
covered with ice or snow. For more
information, contact an authorized
dealer.
Summer tires do not contain the all
season designation or mountain/
snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.
Warning!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
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.

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 conditions 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, servicepractices, 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 on
specified 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 controlled
conditions on a specified indoorlaboratory 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.
Warning!
The temperature grade for this tire
is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
under-inflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
241

STORING THE VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the vehicle in an area that is
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the “Liftgate Emergency
Opening” procedure described in the
“Power Liftgate” section of “Getting To
Know Your Vehicle”.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected from
the electrical system, check its state of
charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds available
commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the painted
surface by dragging any dust that may have accumulated on it. Do not use
compact plastic sheets, as they do not
allow humidity to evaporate from the
surface of the vehicle.
Inflate tires to +7.25 psi (+0.5 bar)
above the standard prescribed pressure
and check it periodically.
Do not drain the engine cooling
system.
Any time the vehicle is left inactive for
two weeks or more, operate the air
conditioning system with engine idling
for at least five minutes, setting external
air and with fan set to maximum speed.
This operation will ensure appropriate
lubrication for the system, thus
minimizing the possibility of damage to
the compressor when the system is
operated again.
Note: After cycling the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP
position and the driver’s side door is
closed.
BODYWORK
Protection Against Atmospheric
Agents
The vehicle is equipped with the best
available technological solutions to
protect the bodywork against corrosion.
These include:
Painting products and systems which
give the vehicle resistance to corrosion
and abrasion.
Use of galvanized (or pre-treated)
steel sheets, with high resistance to
corrosion.
Spraying of plastic parts, with a
protective function in the more exposed
points: underdoor, inner wing, edges, etc.
Use of “open” boxed sections to
prevent condensation and pockets of
moisture which could favor the formation
of rust inside.
Use of special films to protect against
abrasion in exposed areas (e.g. rear wing,
doors, etc.).
Corrosion Warranty
Your vehicle is covered by Corrosion
Warranty against perforation due to rust
of any original element of the structure
or bodywork. For the general terms of
this warranty, refer to the Warranty
Booklet.
