CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
These products 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 dam-
age 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. Do not use any products on Dark Vapor or
Black Satin Chrome Wheels. They will permanently dam-
age this finish and such damage is not covered by the New
Vehicle Limited Warranty.
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 equiva-
lent 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 for a few minutes before doing
so. Driving the vehicle and applying the brakes when
stopping will reduce the risk of brake rotor corrosion.
Dark Vapor Or Black Satin Chrome Wheels
CAUTION!
If your vehicle is equipped with Dark Vapor or Black
Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not covered
by the New Vehicle Limited Warranty. USE ONLY MILD
SOAP AND WATER WITH A SOFT CLOTH. Used on a
regular basis this is all that is required to maintain this
finish.

The suggested Front Wheel Drive (FWD) rotation method
is the “forward cross” shown in the following diagram.
This rotation pattern does not apply to some directional
tires that must not be reversed.The suggested Four Wheel Drive (4WD) Tire rotation
method is the “rearward cross” shown in the following
diagram.
CAUTION!
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to
the power transfer unit. Tire rotation schedule should
be followed to balance tire wear.

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 condi-
tions 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 controlled conditions onspecified 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 con-
trolled 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 performance on the laboratory test wheel, than the
minimum required by law.

•If you carry special cargo such as chemicals, fertilizers,
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 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.
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 immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.).8

In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
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 cali-
brated torque wrench.

TECHNICAL SPECIFICATIONS 513
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
2.4L and 3.2L EnginesThese engines are designed to meet all
emissions regulations and provide opti-
mum fuel economy and performance
when using high quality unleaded
“Regular” gasoline having a posted oc-
tane number of 87 as specified by the
(R+M)/2 method. The use of higher
octane “Premium” gasoline is not required, as it will not
provide any benefit over “Regular” gasoline in these
engines.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a
cause for concern. However, if the engine is heard making
a heavy knocking sound, see your dealer immediately. Use
of gasoline with an octane number lower than 87 can cause
engine failure and may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consider-
ing service for the vehicle.
