272SERVICING AND MAINTENANCE
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the entire
system for leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is needed
to be added to the system please contact an authorized
dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
Organic Additive Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Úpage 260.
Selection Of Coolant
For further information Úpage 306.
NOTE:
Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro -
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is introduced
into the cooling system in an emergency, the cooling
system will need to be drained, flushed, and refilled
with fresh OAT coolant (conforming to MS.90032), by
an authorized dealer as soon as possible. 
Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust inhibitors
or anti-rust products, as they may not be compatible
with the radiator engine coolant and may plug the radi -
ator.
 This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not recom -
mended.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact an
authorized dealer.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
coolant (antifreeze) can be used up to ten years or
150,000 miles (240,000 km) before replacement. To
prevent reducing this extended maintenance period, it is
important that you use the same engine coolant (OAT
coolant conforming to MS.90032) throughout the life of
your vehicle.
Please review these recommendations for using OAT
engine coolant that meets the requirements of the
manufacturer Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/Coolant 10
Year/150,000 Mile (240,000 km) Formula OAT that
meets the requirements of the manufacturer Material
Standard MS.90032. 
Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032 and distilled water. Use
higher concentrations (not to exceed 70%) if tempera -
tures below −34°F (−37°C) are anticipated. Please
contact an authorized dealer for assistance.
 Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount
of corrosion protection in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle is
operated.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system, please contact an
authorized dealer.
 Mixing engine coolant types is not recommended and
can result in cooling system damage. If HOAT and OAT
coolant are mixed in an emergency, have an authorized
dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant will
return to the radiator from the coolant expansion bottle/
recovery tank (if equipped).

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
Safety
 Fuel Economy
 Tread Wear
 Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the stability of
the vehicle and can produce a feeling of sluggish response
or over responsiveness in the steering.
NOTE:

Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
 Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver's side B-pillar or rear edge of the driver's side door.
At least once a month:

Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual judg -
ment when determining proper inflation. Tires may look
properly inflated even when they are underinflated.
 Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always
“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. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
WARNING!
Overloading of your tires is dangerous. Overloading can
cause tire failure, affect vehicle handling, and increase
your stopping distance. Use tires of the recommended
load capacity for your vehicle. Never overload them.
WARNING!
 Improperly inflated tires are dangerous and can
cause collisions.
 Underinflation increases tire flexing and can result in
overheating and tire failure.
 Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause
damage that result in tire failure.
Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
 Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
 Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
 Always drive with each tire inflated to the recom -
mended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.

292SERVICING AND MAINTENANCE
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build-up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or
conditions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle operation.
Refer to an authorized tire dealer or original equipment
vehicle dealer for recommended safe operating speeds,
loading and cold tire inflation pressures.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
The tire has not been driven on when flat.
 The damage is only on the tread section of your tire
(sidewall damage is not repairable).
 The puncture is no greater than ¼ of an inch (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Replace the tire pressure sensor as well as it is not
designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the Run Flat mode it has limited
driving capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a Run Flat tire is
changed after being driven in the Run Flat mode 14 psi
(96 kPa) condition, please replace the TPMS sensor as it
is not designed to be reused.
NOTE:TPMS sensor must be replaced after driving the vehicle on
a flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the Run Flat
mode
Úpage 197.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
WARNING!
High speed driving with your vehicle under maximum
load is dangerous. The added strain on your tires could
cause them to fail. You could have a serious collision.
Do not drive a vehicle loaded to the maximum capacity
at continuous speeds above 75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires on
your vehicle will cause your vehicle to handle poorly.
The instability could cause a collision. Always use radial
ply tires in sets of four. Never combine them with other
types of tires.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds continuously
when you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

294SERVICING AND MAINTENANCE
TIRE TYPES
All Season Tires — If Equipped
All season tires provide traction for all seasons (Spring,
Summer, Autumn, and Winter). Traction levels may vary
between different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on the
tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or on
ice. If your vehicle is equipped with Summer tires, be
aware these tires are not designed for Winter or cold
driving conditions. Install Winter tires on your vehicle when
ambient temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more information,
contact an authorized dealer.
Summer tires do not contain the all season designation or
mountain/snowflake symbol on the tire sidewall. Use
Summer tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
mountain/snowflake symbol on the tire sidewall.
If you need snow tires, select tires equivalent in
size and type to the original equipment tires.
Use snow tires only in sets of four; failure to do
so may adversely affect the safety and handling
of your vehicle.

Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.

While studded tires improve performance on ice, skid and
traction capability on wet or dry surfaces may be poorer
than that of non-studded tires. Some states prohibit
studded tires; therefore, local laws should be checked
before using these tire types.WARNING!
 Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and wheels
may change suspension dimensions and perfor -
mance characteristics, resulting in changes to
steering, handling, and braking of your vehicle. This
can cause unpredictable handling and stress to
steering and suspension components. You could
lose control and have a collision resulting in serious
injury or death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.
 Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
 Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size may
result in false speedometer and odometer readings.WARNING!
Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury or
death. Driving too fast for conditions also creates the
possibility of loss of vehicle control.

298SERVICING AND MAINTENANCE
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle 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 increase tread life, help to maintain
mud, snow and wet traction levels, and contribute to a
smooth, quiet ride.
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed
Úpage 259.
The suggested rotation method is the “forward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be
reversed.

Tire Rotation (Forward Cross)

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
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 clearance
between tires and other suspension components, it
is important that only traction devices in good condi -
tion 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). Auto -
sock 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 instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating 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.
