SNOW TRACTION DEVICES
Use of traction devices require sufficient tire-to-body clearance. Due to limited clearance the following traction devices are recommended. Follow these
recommendations to guard against damage.
Snow traction device must be of proper size for the tire, as recommended by the traction device manufacturer.
No other tire sizes are recommended for use with a tire chain or traction device.
Please see the following table for the recommended tire size, axle and snow traction device:

Trim Level Axle
Tire/Wheel Size Snow Traction Device (Maximum Projection Beyond Tire Profile Or
Equivalent)
All FrontLT225/75R16E
225/75R16C Quality Chain Corp Light Truck Highway Service (Non-Cam) tire chain
or equivalent is recommended.
WARNING!

Using tires of different size and type (M+S, Snow)
between front and rear axles can cause
unpredictable handling. You could lose control and
have a collision.

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).
Autosock traction devices do not require
retightening.
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 a prolonged period on dry
pavement.
CAUTION!

264SERVICING AND MAINTENANCE
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates.

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season
type tires. Rotation will increase tread life, help to
maintain mud, snow and wet traction levels, and
contribute to a smooth, quiet ride.

Refer to the Maintenance Plan for the proper
maintenance intervals Úpage 222. The reasons
for any rapid or unusual wear should be corrected
prior to rotation being performed.
The suggested 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.

Tire Rotation (Forward Cross)

DEPARTMENT OF TRANSPORTATION
UNIFORM 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 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 controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.

Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed of
the device manufacturer’s if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!

23_VF_OM_EN_USC_t.book Page 264

SERVICING AND MAINTENANCE265
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 performance on
the laboratory test wheel, than the minimum
required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than
3 weeks, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from the battery.
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting prior to storing. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
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 corrosive to the metal in
your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold
weather, and other extreme conditions will have an
adverse affect on paint, metal trim, and underbody
protection.
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 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
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.
WARNING!

The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure.

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 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. Use precautions to not
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 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.
If your vehicle is damaged due to a collision or
similar cause that destroys the paint and protec
-
tive coating, have your vehicle repaired as soon
as possible.
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. An 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.
CAUTION!
Do not use abrasive or strong cleaning mate -
rials 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.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.

LEATHER SURFACES
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.

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 recommends
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 rearview mirror, spray cleaner
on the towel or cloth that you are using. Do not
spray cleaner directly on the mirror.
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.

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 lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake System Warning Light.
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 calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.

loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).
Torque Patterns

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.
FUEL REQUIREMENTS

While operating on gasoline with the required octane
number, 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 a
dealer immediately. Use of gasoline with a lower than
recommended octane number 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 considering service for the vehicle.
3.6L ENGINE
This engine is designed to meet all
emission regulations and provide
optimum fuel economy and performance
when using high quality unleaded regular
gasoline having a posted octane 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.WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
