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 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.
Special Care
If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar
-
riage 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 respon -
sibility of the owner.
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.

PLASTIC AND COATED PARTS
Use Mopar Total Clean to clean vinyl upholstery.
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.

1. 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.

2. Dry with a soft cloth.
LEATHER PARTS
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. Application of a leather conditioner
is not required to maintain the original
condition.
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 FCA recom -
mends 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!
Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani -
tizers to the plastic, painted, or decorated
surfaces of the interior may cause perma -
nent damage. Wipe away immediately.
Damage caused by these type of products
may not be covered by your New Vehicle
Limited Warranty.
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.

IDENTIFICATION DATA
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is on
the left front corner of the instrument panel. The
VIN is visible from outside of the vehicle through
the windshield.
Windshield VIN Location

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some loss
of overall braking effectiveness. This may be
evident by increased pedal travel during
application, greater pedal force required to slow
or stop, and potential activation of the Brake
Warning Light.
In the event power assist is lost for any reason
(for example, repeated brake applications with
the engine off), the brakes will still function. The
effort required to brake the vehicle will be much
greater than that required with the power
system operating. SRT — If Equipped
NOTE:
Your vehicle is equipped with a high perfor
-
mance braking system. The brake pads are a
semi-metallic compound, which offer superior
fade resistance for consistent operation. A
compromise to using this type of brake pad is
that the brakes may produce more brake dust
and may squeal slightly under certain weather
and operating conditions (i.e., during light brake
applications). These are considered normal
conditions.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a high quality six
sided (hex) deep wall socket.

REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“Reformulated Gasoline”. Reformulated
gasoline contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
The use of reformulated gasoline is
recommended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.

20_LA_OM_EN_USC_t.book Page 294

TECHNICAL SPECIFICATIONS295
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
performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in
minimizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent gasoline is recommended. 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 solvents or similar
ingredients. These can harm fuel system gasket
and diaphragm materials.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol.
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
or not be covered under New Vehicle Limited
Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible
with gasoline containing up to 15% ethanol
(E-15). Use of 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 symptoms:
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
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed 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
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends may
result in starting and drivability problems,
damage critical fuel system components,
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
15% ethanol (E-15).

296TECHNICAL SPECIFICATIONS
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
performance in some vehicles. The
manufacturer recommends 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 CAUTIONSNOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
CARBON MONOXIDE WARNINGS
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni -
tion 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 malfunc -
tioning and may require immediate service.
Contact an 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 concentrations of methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
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 abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.
