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 will
maintain proper position.
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 manu-
facturer 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 condi-
tions on specified 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
controlled conditions on a specified indoor laboratory
test wheel.
416 SERVICING AND MAINTENANCE

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 pas-
senger 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 temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
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
conditioning 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 geo-
graphic 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 protec-
tion.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.

SERVICING AND MAINTENANCE 417

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. 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
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.

SERVICING AND MAINTENANCE 419

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.
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.
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.).
Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
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.
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.

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 and underbody as well as the Automobile Informa-
tion Disclosure Label affixed to a window on your vehicle,
the vehicle registration and title.
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 in-
crease 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.
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.

Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a
second time to verify that specific torque has been
achieved. Retighten to specifications after 25 miles (40 km)
and check the lug nut/bolt torque to be sure that all the lug
nuts/bolts are properly seated against the wheel.It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the bolt
holes in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers
of operation to allow the wheel nuts to become properly
set. All wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to recom-
mended torque. Tighten the wheel nuts to final torque in
increments. Progress around the bolt circle, tightening the
wheel nut opposite to the wheel nut just previously
tightened until final torque is achieved.
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.

NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide 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 main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.

CYBERSECURITY
Your vehicle may be a connected vehicle and may be
equipped with both wired and wireless networks. These
networks allow your vehicle to send and receive informa-
tion. This information allows systems and features in your
vehicle to function properly.
Your vehicle may be equipped with certain security fea-
tures to reduce the risk of unauthorized and unlawful
access to vehicle systems and wireless communications.
Vehicle software technology continues to evolve over time
and FCA US LLC, working with its suppliers, evaluates
and takes appropriate steps as needed. Similar to a com-
puter or other devices, your vehicle may require software
updates to improve the usability and performance of your
systems or to reduce the potential risk of unauthorized and
unlawful access to your vehicle systems.
The risk of unauthorized and unlawful access to your
vehicle systems may still exist, even if the most recent
version of vehicle software (such as Uconnect software) is
installed.
WARNING!
•It is not possible to know or to predict all of the
possible outcomes if your vehicle’s systems are
breached. It may be possible that vehicle systems,
including safety related systems, could be impaired
or a loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• ONLY insert media (e.g., USB, SD card, or CD) into
your vehicle if it came from a trusted source. Media
of unknown origin could possibly contain malicious
software, and if installed in your vehicle, it may
increase the possibility for vehicle systems to be
breached.
• As always, if you experience unusual vehicle behav-
ior, take your vehicle to your nearest authorized
dealer immediately.
