painted and vinyl surfaces, care should
be taken to avoid its contact with these
surfaces.
• Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required, therefore the trans-
mission has no dipstick. Your authorized
dealer can check your transmission fluid
level using special service tools. If you notice
fluid leakage or transmission malfunction,
visit your authorized dealer immediately to
have the transmission fluid level checked.
Operating the vehicle with an improper fluid
level can cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit
your authorized dealer immediately. Se-
vere transmission damage may occur. Your
authorized dealer has the proper tools to
adjust the fluid level accurately.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solutionand can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump-Starting” in “In
Case Of Emergency” for further informa-
tion.
WARNING!
• Battery gas is flammable and explosive.Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
CAUTION!
• It is essential when replacing the cableson the battery that the positive cable is
attached to the positive post and the
negative cable is attached to the nega-
tive post. Battery posts are marked posi-
tive (+) and negative (-) and are identi-
fied on the battery case. Cable clamps
should be tight on the terminal posts
and free of corrosion.
• If a “fast charger” is used while the
battery is in the vehicle, disconnect both
vehicle battery cables before connecting
the charger to the battery. Do not use a

TIRES
Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures and Tire Loading.
Tire Markings
NOTE:
• P (Passenger) — Metric tire sizing isbased on U.S. design standards. P-Metric
tires have the letter “P” molded into the
sidewall preceding the size designation.
Example: P215/65R15 95H. • European — Metric tire sizing is based on
European design standards. Tires de-
signed to this standard have the tire size
molded into the sidewall beginning with
the section width. The letter "P" is absent
from this tire size designation. Example:
215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size
designation for LT-Metric tires is the same
as for P-Metric tires except for the letters
“LT” that are molded into the sidewall
preceding the size designation. Example:
LT235/85R16.
• Temporary spare tires are designed for temporary emergency use only. Temporary
high pressure compact spare tires have
the letter “T” or “S” molded into the
sidewall preceding the size designation.
Example: T145/80D18 103M.
• High flotation tire sizing is based on U.S. design standards and it begins with the
tire diameter molded into the sidewall.

Tire Terminology And Definitions
TermDefinition
B-Pillar The vehicle B-Pillar is the structural member of the body located behind the front
door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting
for a minimum of three hours. Inflation pressure is measured in units of PSI (pounds
per square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation pres-
sure for this tire. The maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire
placard.
Tire Placard A label permanently attached to the vehicle describing the vehicle’s loading capacity,
the original equipment tire sizes and the recommended cold tire inflation pressures.
SERVICING AND MAINTENANCE

NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the
front and rear axles must not be exceeded.
For further information on GAWRs, vehicle
loading, and trailer towing, refer to “Vehicle
Loading” in the “Starting And Operating”
section of this manual.
To determine the maximum loading condi-
tions of your vehicle, locate the statement
“The combined weight of occupants and
cargo should never exceed XXX kg or XXX lbs”
on the Tire and Loading Information placard.
The combined weight of occupants, cargo/
luggage and trailer tongue weight (if appli-
cable) should never exceed the weight refer-
enced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX kg
or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity. For example, if “XXX”
amount equals 1400 lbs. and there
will be five 150 lb passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5x150) = 650 lbs.)
(5)Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely ex-
ceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg
and there will be five 68 kg passengers in
your vehicle, the amount of available cargo
and luggage load capacity is 295 kg (635-
340 (5x68) = 295 kg) as shown in step 4.
NOTE:
• If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. The following table shows ex-
amples on how to calculate total load,
cargo/luggage, and towing capacities of
your vehicle with varying seating configu-
rations and number and size of occupants.
This table is for illustration purposes only
and may not be accurate for the seating
and load carry capacity of your vehicle.
• For the following example, the combined weight of occupants and cargo should
never exceed 865 lbs (392 kg).

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially alumi-
num and chrome plated wheels, should be
cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the
same soap solution recommended for the
body of the vehicle.
Your wheels 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. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do notuse harsh chemicals or a stiff brush. They
can damage the wheel’s protective coating
that helps keep them from corroding and
tarnishing.
NOTE:
Many aftermarket wheel cleaners contain
strong acids or strong alkaline additives that
can harm the wheel surface.
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. These prod-
ucts and automatic car washes may dam-
age the wheel's protective finish. Such
damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap,
MOPAR Wheel Cleaner or equivalent is
recommended.
When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken
in the selection of tire and wheel cleaning
chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or
Mopar Chrome Cleaner or their equivalent is recommended or select a non-abrasive, non-
acidic cleaner for aluminum or chrome
wheels. Do not use any products on Dark
Vapor or Black Satin Chrome Wheels. They
will permanently damage this finish and such
damage is not covered by the New Vehicle
Limited Warranty.
CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap, MOPAR
Wheel Cleaner or equivalent is recom-
mended.
NOTE:
If you intend parking or storing your vehicle
for an extended period after cleaning the
wheels with wheel cleaner, drive your vehicle
for a few minutes before doing so. Driving the
vehicle and applying the brakes when stop-
ping will reduce the risk of brake rotor corro-
sion.
SERVICING AND MAINTENANCE

These effects can be reduced by timely rota-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off-Road 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. More frequent
rotation is permissible if desired. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position fol-
lowing a tire rotation.
The suggested rotation method is the
“rearward-cross” shown in the following dia-
gram.
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 signifi-
cantly from the norm due to variations in
driving habits, service practices, and differ-
ences 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.
