396SERVICING AND MAINTENANCE
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. Stub -
born 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 condi -
tion.
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.

TECHNICAL SPECIFICATIONS401

MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic addi -
tive 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 manufac -
turer 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 Cautions
NOTE:
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.
CAUTION! (Continued)
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.

Regulatory And Safety Information
USA/CANADA
Exposure to Radio Frequency Radiation
The radiated output power of the internal wire -
less radio is far below the FCC and IC radio
frequency exposure limits. Nevertheless, the
wireless radio will be used in such a manner
that the radio is 8 in (20 cm) or further from the
human body.
The internal wireless radio operates within
guidelines found in radio frequency safety stan -
dards and recommendations, which reflect the
consensus of the scientific community.
The radio manufacturer believes the internal
wireless radio is safe for use by consumers. The
level of energy emitted is far less than the elec -
tromagnetic energy emitted by wireless devices
such as mobile phones. However, the use of
wireless radios may be restricted in some situa-
tions or environments, such as aboard
airplanes. If you are unsure of restrictions, you
are encouraged to ask for authorization before
turning on the wireless radio.
The following regulatory statement applies to all
Radio Frequency (RF) devices equipped in this
vehicle: This device complies with Part 15 of the FCC
Rules and with Innovation, Science, and
Economic Development Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions:

1. This device may not cause harmful interfer
-
ence, and

2. This device must accept any interference received, including interference that may
cause undesired operation.
Le présent appareil est conforme aux CNR
d`Innovation, Science and Economic Develop -
ment applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux
conditions suivantes:

1. l'appareil ne doit pas produire de brouil -
lage, et

2. l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en comprom -
ettre le fonctionnement. La operación de este equipo está sujeta a las
siguientes dos condiciones:

1. es posible que este equipo o dispositivo no
cause interferencia perjudicial y

2. este equipo o dispositivo debe aceptar cual -
quier interferencia, incluyendo la que
pueda causar su operación no deseada.
NOTE:
Changes or modifications not expressly
approved by the party responsible for compli -
ance could void the user’s authority to operate
the equipment.
NOTE:
This equipment has been tested and found to
comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reason -
able protection against harmful interference
in a residential installation. This equipment
generates, uses and can radiate radio
frequency energy and, if not installed and
used in accordance with the instructions,
may cause harmful interference to radio
communications. However, there is no guar -
antee that interference will not occur in a
particular installation.
