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 re-
sult 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.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stabil-
ity 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 abnor-
mal 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 pre-
vent 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 pres-
sure 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.
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

wheel. Keep inflated to the cold tire inflation pres-
sures 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 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!
To avoid damage to your vehicle or tires, observe
the following precautions:
•Because of restricted traction device clearance
between tires and other suspension components,
it is important that only traction devices in good
condition 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.
• Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for prolonged period on dry pave-
ment.
• Observe the traction device manufacturer ’s in-
structions on the method of installation, operat-
ing speed, and conditions for use. Always use the
suggested operating speed of the device manufac-
turer ’s if it is less than 30 mph (48 km/h).
(Continued)
CAUTION! (Continued)
•Do not use traction devices on a compact spare
tire.
Tire Rotation Recommendations
Due to tire design and size, tire rotations on this vehicle
are not possible.
NOTE: For AR 4C models, where available, the vehicle
may be equipped with high performance tires that
guarantee high grip performance with little increase of
wear. Alfa Romeo, in collaboration with Pirelli, devel-
oped a specific high performance tire for the 4C model.
A dedicated Pirelli PZero, identified with an AR mark,
guarantees this vehicle to obtain the highest perfor-
mance capable.
DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were estab-
lished by the National Highway Traffic Safety Ad-
ministration. The specific grade rating assigned by
the tire’s manufacturer in each category is shown on
the sidewall of the tires on your vehicle. 8
SERVICING AND MAINTENANCE 251

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, 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.
252 SERVICING AND MAINTENANCE

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.
• If the engine compartment is washed with an
high pressure jet, keep it at a distance of at least 8
inches (20 centimeters) from filler surface.
• Do not run this vehicle through an Automatic Car
Wash facility as extensive damage can result due
to the vehicle’s low ground clearance.
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.
NOTE:
If the belts retract slowly, inspect the upper
turning loop for soiling. If soiling is present, clean with
a wet soft cloth until all residue is removed.
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 imme-
diately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after a colli-
sion if they have been damaged (i.e., bent retractor,
torn webbing, etc.).

Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
that have these additives will help improve fuel
economy, reduce emissions, and maintain vehicle per-
formance.Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in mini-
mizing engine and fuel system de-
posits. When available, the usage of
Top Tier Detergent gasoline is recom-
mended. Visit www.toptiergas.com
for a list of TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 10% ethanol (E-10). Use
of these blends may result in starting and drivabil-
ity problems, damage critical fuel system compo-
nents, cause emissions to exceed the applicable
standard, and/or cause the “Malfunction Indicator
Light” to illuminate. Please observe pump labels as
they should clearly communicate if a fuel contains
greater than 10% ethanol (E-10).
Problems that result from using gasoline containing
more than 10% ethanol (E-10) or gasoline containing
methanol are not the responsibility of the manufacturer
and may void or not be covered under New Vehicle
Limited Warranty.

TECHNICAL SPECIFICATIONS 263

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 10% ethanol (E-10). Gasoline with
higher ethanol content may void the New Vehicle
Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symp-
toms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on com-
pressed natural gas (CNG) or liquid propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic additive
that is blended into some gasoline to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance in some vehicles. The manufacturer recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be
indicated on the gasoline pump; therefore, you should
ask your gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Fed-
eral law. Using leaded gasoline can impair engine

performance and damage the emissions control
system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with
the engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
• Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
