5. For a rear tire, place the jack and protective
cap in the slot on the rear tie-down bracket, just
forward of the rear tire (as indicated by the
triangular lift point symbol on the sill molding).
Do not raise the vehicle until you are sure
the jack is fully engaged.6. Raise the vehicle by turning the jack screw
clockwise. Raise the vehicle only until the tire
just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire
lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the nuts.
To avoid the risk of forcing the vehicle off the
jack, do not tighten the nuts fully until the
vehicle has been lowered.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. Finish tightening the lug nuts. Push down
on the wrench while tightening for increased
leverage. Alternate nuts until each nut has
been tightened twice. The correct wheel nut
tightness is 95 ft lbs (130 N·m). If in doubt about
the correct tightness, have them checked with
a torque wrench by your authorized dealer or at
a service station.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.

ONBOARD DIAGNOSTIC SYSTEM –
OBD II
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light” (MIL). It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel
economy and drivability. The vehicle must
be serviced before any emissions tests can
be performed.
• If the MIL is flashing while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gascap indica-
tor will display in the EVIC telltale
display area. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly
and press the SELECT button to turn off the message. If the problem continues, the mes-
sage will appear the next time the vehicle is
started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
REPLACEMENT PARTSUse of genuine MOPAR
parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
MAINTENANCE PROCEDURESThe pages that follow contain the required
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed maintenance schedule, there are
other components which may require servicing
or replacement in the future.

fluid, make certain that the dipstick cap is
properly reseated. It is normal for the dipstick
cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in
the dipstick tube.
Appearance Care and Protection
from Corrosion
Protection of Body and Paint from
Corrosion
Vehicle body care requirements vary according
to geographic locations and usage. Chemicals
that make roads passable in snow and ice, and
those that are sprayed on trees and road
surfaces during other seasons, are highly cor-
rosive to the metal in your vehicle.
The following maintenance recommendations
will enable you to obtain maximum benefit from
the corrosion resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or re-
moval 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.
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 or
equivalent 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.
CAUTION!
• Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder, which will scratch metal and
painted surfaces.
• Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or re-
moval of paint and decals.
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 tail-
gate must 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 re-
sponsibility of the owner.
• If your vehicle is damaged due to an acci-
dent or similar cause which destroys the
paint and protective coating, have your ve-
287

clean your leather upholstery. Application of a
leather conditioner is not required to maintain
the original condition.
WARNING!
Do not use volatile solvents for cleaning pur-
poses. Many are potentially flammable, and if
used in closed areas, they may cause respi-
ratory harm.
Cleaning Headlights
Your vehicle has plastic headlights 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 mate-
rial to clean the lenses.
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 cau-
tion when cleaning inside rear windows
equipped with electric defrosters. Do not use
scrapers or other sharp instruments which may
scratch the elements.
When cleaning the rearview mirror, spray
cleaner on the towel or rag that you are using.
Do not spray cleaner directly on the mirror.
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 rag. 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 rag.
2. Dry with a soft tissue.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This
will weaken the fabric. Sun damage will 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.
Replace the belts if they appear frayed or worn
or if the buckles do not work properly.
Dry with a soft tissue.
