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 aggressive tread designs such
as those on all season type tires. Rotation will
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 clear -
ance between tires and other suspension
components, it is important that only trac-
tion 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.
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 if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.

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.
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
When replacing a flat, the spare tire may
have to be remounted on the rim, or
installed at a different location, to maintain
the correct placement of the tire on the
wheel relative to the tire/wheel position on
the truck. For example, if the spare is used
to replace an outer rear tire it will have to be
remounted on the rim so that the wheel is
dished inward. That way the tread design of
asymmetrical tires and the white writing of
the OWL tires will maintain proper position.
CAUTION! (Continued)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.

Tri-Fold Soft Tonneau Cover Care — If
Equipped
For cleaning and protecting the vinyl Tri-Fold
Tonneau cover, use Mopar Whitewall & Vinyl
Top Cleaner and Mopar Leather and Vinyl
Conditioner/Protectant.
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 clear 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. 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.
Bumper Care
The customer is responsible to clean and
maintain the chrome components of the
vehicle. Washing away road debris and salt
using an automotive soap. Bumpers should be
cleaned regularly using mild (neutral Ph) soap
and water to maintain their luster and to
prevent corrosion.
Your bumpers are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other road
chemicals used to melt ice or control dust on
dirt roads. Do not use harsh chemicals or a stiff
brush. They can stain or damage the protective
coating that helps keep them from corroding
and tarnishing.
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
trunk be kept clear and open.
CAUTION!
Do not use abrasive or strong cleaning
materials 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.
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes, or oven cleaner. These
products may damage the bumper’s
protective finish. Such damage is not covered
by the New Vehicle Limited Warranty. Only car
wash soap, Mopar Chrome Cleaner, or
equivalent is recommended.
Avoid products or automatic car washes that
use acidic solutions, strong alkaline additives,
or harsh brushes. Many aftermarket cleaners
and automatic car washes may damage the
bumper’s protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar Chrome
Cleaner, or equivalent is recommended.

If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the respon -
sibility 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 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.
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 Conditioner available at a 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. Spray-On Bedliners are chemically-resistant to
many different types of chemicals (including
gasoline, oil, hydraulic fluids) for short periods
of time. If a spill occurs on your Spray-On
Bedliner, rinse the truck out as soon as possible
to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage
a Spray-On Bedliner. One common condition is
when loading a heavy pallet and dragging that
pallet across the floor of the bed. If a nail or
sharp point is exposed under the weight of the
pallet a scratch or tear is possible. While not
covered by your new vehicle warranty, a
cosmetic fix to cover the metal exposed by the
scratch is required. To repair a tear or gouge,
follow the directions provided in the Mopar
Quick Repair Kit.
WARNING!
Do not use silicon-based protection products
to clean your bedliner. Silicon-based products
can become slippery and may result in
personal injury.

turning loop for soiling. If soiling is present,
clean with a wet soft cloth until all residue is
removed.
PLASTIC AND COATED PARTS
Use Mopar Total Clean to clean vinyl upholstery.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.
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.).
CAUTION!

ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system
components. Problems that result from running
CNG or LP are not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic
additive 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
manufacturer 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
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.8
