Tire Rotation Recommendations
Tires on the front and rear axles of vehicles 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 aggres-
sive tread designs such as those on all season type tires. Rota -tion 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. More frequent rotation is permissible if desired.
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the “rearward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be reversed.
Tire Rotation (Rearward Cross)
• Install device as tightly as possible and then retighten
after driving about ½ mile (0.8 km).
• 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.
• Observe the traction device manufacturer’s instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested oper -
ating 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!

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 charac-
teristics 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 spec
-
ified government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature Grades
The Temperature grades are A (the highest), B, and C, repre -
senting the tire's resistance to the generation of heat and its
ability to dissipate heat, when tested under controlled condi -
tions on a specified indoor laboratory test wheel.
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.

SERVICING AND MAINTENANCE 539
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 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle's battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of service(i.e., vacation) for two weeks or more, run the air condi -
tioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again.
BODYWORK
Protection From Atmospheric Agents
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 effect 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.
WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.

Special Care
• If you drive on salted or dusty roads or if you drive nearthe 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. The cost of such repairs is
considered the responsibility of the owner.
• If your vehicle is damaged due to a collision or similar cause that destroys the paint and protective coating, have
your vehicle repaired as soon as possible. The cost of such
repairs is considered the responsibility of the owner.
• If you carry special cargo such as chemicals, fertilizers, de-icer salt, etc., be sure that such materials are well pack -
aged 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. Spray-On Bedliner – If Equipped
During ownership, the shine and luster of the Spray-On
Bedliner can fade from oxidation, road dirt, heavy-duty
hauling and hard water stains. Weathering and UV exposure
will lead to fading, dulling, and loss of gloss over time.
To help maintain the appearance of your Spray-On Bedliner,
the manufacturer recommends you periodically rinse all
loose dirt from your truck bed and clean your truck at least
twice per year using the Mopar Spray-On Bedliner Condi
-
tioner available at your local authorized dealer.
To Help Maintain The Appearance Of Your Spray-On
Bedliner, Follow The Steps Below:
1. Rinse your truck bed out with water to remove any loose dirt and debris.
2. Mix a mild soap or detergent with water with a soft cloth or brush.
3. Rinse bedliner with water.
4. Once dry, apply a small amount of Mopar Spray-On Bedliner Conditioner to a moist towel or sponge and wipe
over the entire surface of the truck bedliner.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the left
front corner of the instrument panel, visible through the
windshield. This number also appears on the vehicle frame
etched on right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a window on your
vehicle, the vehicle registration and title.Vehicle Identification Number
NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
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.
