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 specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor -
mance. 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.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.

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.

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 luke-
warm 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.
NOTE:
If the belts retract slowly, inspect the upper 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.
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 cloth. 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
cloth.
2. Dry with a soft cloth.
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!
• Direct contact of air fresheners, insect repellents, suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may cause
permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be covered by your New Vehicle Limited Warranty.

Leather Parts
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. Application of a
leather conditioner is not required to maintain the original
condition.
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 rear view 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.

TECHNICAL SPECIFICATIONS 565
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.
Hydraulic Brake Assist — 2500/3500 Models Only
(Except Power Wagon)
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature.
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.

Fuel System Cautions
NOTE:
Intentional tampering with the emissions control system can
result in civil penalties being assessed against you.
Carbon Monoxide Warnings
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 perfor -
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition malfunctions can cause the catalytic converter to over -
heat. If you notice a pungent burning odor or some
light smoke, your engine may be out of tune or
malfunctioning 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 performance problems
resulting from the use of such fuels or additives is not the
responsibility of the manufacturer and may void or not
be covered under the New Vehicle Limited Warranty.
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas, which can kill.
Never run the engine in a closed area, such as a garage,
and never sit in a parked vehicle with the engine
running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
